Exactly what the title said. Do any of you have actual experience with 8" subs?
In my new Supercrew, I've located a spot that will be perfect for a pair of 8s, where I can still keep 100% functionality of my seats, the space under the seats, and everything else. The only problem is, I've never used, installed, nor even heard a setup running 8" subs.
I know it's going to be a huge change from the Earthquake DBX 12 that I just got for my Blazer, but that's a sacrifice I'll make any day to be driving my new truck.
Thanks for all of your input.

Back in the days i ran four 8" Kicker Comps and those little things were amazingly aggressive. Those little sucker bumped like i couldnt believe. You obviously wont get what you can from 12's but they dont sound half bad. Wait for Swez and ttocs to reply cause im sure they can suggest some of the new manufacturers that have good stuff...
Swez on 08/1/2003 22:42:59
Say more about the amp and power you have to feed these 8" subs.
In the right enclosure space, proper ohms match to your amp, this will work to your amazement. Depends on if you are looking for SPL or SQ or a mix of both.
The key here, is the sub and enclosure matching the amp and able to take enough power to meet your needs. Don't think of a moment that a pair of 8's has to mean weenie bass. Careful system matching and planning, will net some very nice results.
After all, we are talking ~16" of cone area here in all....
Comments on amp please,

I ran a set of Rocford 8s in a hatchback and they hit good. They are also good for a small space, if you have the right amp. Now they are not 12s and will not hit as hard . You might try a set of 10s if you have the room they are a little better.
ttocs on 08/2/2003 00:51:52
I recently installed 4 - 8"s in a tercel with a 250 watt amp. They sounded better then I thought they would....
I also owned 2 - jl 8"s in my old ranger. I was not all that impressed with them to be honest.
Swez's Q hit the nail on the head. You can get very good sound an bass from an 8 if it is done right.
Tray on 08/4/2003 12:47:17
Swez,
Well, I have quite a selection of possibilities as far as amps go.
My options are as follows.
Rockford Fosgate Punch 200.2
Rockford Fosgate Punch 250.2
MTX 300d
JBL BP600.1
Cadence A7HC
And if it meant getting something new, I'm willing.
baine,
I wish I had room for 10s or 12s, but realistically, I'm going to have a hard enough time getting enough airspace for the 8s, let alone trying to go bigger.
As for the comments about getting good bass from the 8s, that is my plan, it's only that I have no personal experience running 8s as subs, so I though if anyone here had run them before, and had some insight, it may assist me in my hunt. I know it'll take some experimentation, and patience, as all my systems in the past have.
Thanks all.

There are also a bunch that are too deep for the area I have available as well.
Tray on 08/4/2003 16:16:21
Well, I'm not trying to get a huge amount of SPL. I've had my fun in that game, and know exactly what I'd do if I had an SUV with enough space to put up those huge numbers.
I'm now looking for a great sounding system, without giving up the space in my truck. I need every bit of it, and have figured out that I can get 8s that are no more than 4 inches deep, and give them each up to .8 cubic feet.
Swez on 08/4/2003 17:00:24
OK, let's set additional parameters into the mix and define one part of the equation... the amp!
If you go with ~ 300-500 watts RMS, (1/2 per sub) there are a number of subs that will do the job in the list mentioned. Can you boil the amp selection down to 2-3 amps you have interest in. Consider a 2 channel as choices 1&2 and a Class D map for #3, in the power range of your choice. This gives us some wiggle room for sub ohms choices.
Also, if you want more power and SPL from a given sub, the mass and depth of the sub will probably surpass the 4 inch depth noted. However, by manipulating the way the sub fires in the enclosure, it just might work in a wedge design with a deeper sub basket.
The 0.8 cf per sub seems like a generous amount to play with. Can we get some input on the H, W & D limits of our installation as well... that will help as we move to the next phase... sub selection criteria.
Will ask for sub amp web links as you pick them out so we can review them and try to help match the subs to your amp choice(s).
Swez
PS With careful planning and well choosen woofers, I think you will be very happy with the results, if your expectations are in line with the limits of a pair of 8's. Most of this will be the enclosure that makes or fails this test.
ttocs on 08/4/2003 23:09:24
alot of tens can use .5 cf per sub. You might be able to fit 2 8's in that space..
Relax_The_Mind on 08/5/2003 06:25:30
Tray,
I've seen, heard, and was impressed by two 8" polks (DX8s) crammed into a small (but ported) box and an old school 500w kenwood amp in a jeep. Ive installed a pair 8"s in a celica and an old civic both sounding quite excellent. Only difference I notice is that it doesnt hit as low as 10"s or 12"s but sounds just as loud to me.
I have to agree and its one of my main beliefs in car audio is that a good sub is only good when paired with a good box. Kind of see it when you look at higher end manufacturers are basically the only ones who give you help on building good boxes. I'd say pick the sub that best fits the exact internal airpspace of the box you make. Noting the bottom wood is already braced by the floor so you can use thinner sheet of MDF if space is really that tight.
Orientation is key too because its similar to figuring out where to point the home theatre subwoofer to get the best sound throughout the room. One install I did for my best friend's truck (toyota tacoma) got best SPL when he used the "V" configuration pointing towards the corners of the roof (under the seat im not sure if that matters...
ttocs,
Really? I always thought those JL 8"s sounded pretty decent (SQ) in that prefrab half circle JL box.
RTM
Tray on 08/5/2003 13:32:08
Alright, here we go.
Swez,
I guess I didn't explain myself clearly. By selection, I mean going out to my garage, and picking one up. I have those mentioned amplifiers already, just itching to be put to use.
As far as stats go,
Rockford Fosgate Punch 200.2 = 374 x 2 @ 4ohm
Rockford Fosgate Punch 250.2 = 414 x 2 @ 4ohm
MTX 300d = 150 watts x 1 @ 4ohm & 300x1 @ 2ohm
JBL BP600.1 = 300 x 1 @ 4ohm & 600x1 @ 2ohm
Cadence A7HC = 500 x 1 @ 4 ohm & 800 x 1 @ 2 ohm & 1400 x 1 @ 1 ohm.
If you still need me to narrow it down, I'd like to run them in this order of preference.
1. JBL
2. MTX
3. RF 200.2
4. RF 250.2
5. Cadence (Only due to power draw, this is my favorite amp, but I doubt I'll need 1400 watts for 8s)
Next, installation.
I will try to take a picture to post tonight, so you can see where I'm looking to house the subs. Basically if you were to imagine the area behind the seat in a regular cab pickup, it is very similar, only with a plastic cover over the entire thing, with 2 9"x18" openings to access the storage area. My plan is to replace the opening covers, and expand out into the storage area which is available
You can sort of see what some others have done with this area.

http://www.fordtruckworld.com/gallery/Darkshadowscrew/210636.jpg
Keep in mind, these are just pix of the driver side, and the passenger side has the same thing available.
As far as dimensions go, basically I'm looking at a wedge that starts at ~3 1/4 inches deep, and ends at ~5 1/2 inches deep at the bottom, which is ~17 inches down, of which, 5 inches are below the opening shown in the pics. I also have available nearly 23 inches of width to play with for each side, before I'd have to look at modding the framework (which I'm not going to do).
I built a little prototype out of a salad plate, a soup bowl, and some cardboard, and figured that if I stay at 4" of depth or smaller, I will have about 1/3 inch of clearance behind the magnet at the top, and just under one inch of clearance at the bottom. While not much, I am hoping this would be enough to allow proper ventilation.
RTM,
I wish I could use MDF, but I'm already to the point, where fiberglass is going to be my only option. Luckily I'll have the top, bottom and back, all supported by the steel frame, the front will be MDF, and depending on how wide I need to go, I may be able to make the sides MDF as well.
I wish I had a choice on the direction they'll be firing, but with the way things are looking, I am only going to have about 3 or 4 degrees of movement that I can play with.
Oops, almost forgot the amp links.

i did an install in my neightbors ford 150 '97 dunno if its the same or not, but there is plenty of room under the back bench to place amps. we just used the bench bolt for the ground so no drilling or anything was needed, we didnt custom any subs or anything, we just used his alpine bandpass out of his mustang gt, just swapped it he ever went anywhere in his truck. i think the truck sounds really cool with a system. all that cabin space and everyhting, made it sound really good.

oh my bad. didnt see that ya wanted to keep the room underneath the seats sry

Tray on 08/5/2003 15:52:11
It's probably similar to the 2000 SuperCab I had. In that I bought a lift kit for the rear seat, and had 2 10s running on the A7HC. Was metered at 152 on the dash, and I loved it.
Unfortunately the kids and wife hated it, and now that I am back around to a truck again (this time one that fits carseats), I need to keep the functionality, but want to make it a pleasure to drive as well.
Swez on 08/5/2003 15:47:13
OK Tray, thanks for spelling it out in very good detail and yes, I have seen pics of guys who glassed in the flooring area with a custom frame and it came out very well.
You have a very nice selection of amps and I agree that for power amps, the JBL makes good sense if you use a pair of 4 ohm SVC's. The other 2 channel amps mentioned are all well and good too. They could be most useful if you wound up using 8 ohm subs.
The hard part here, is finding a quality set of subs with such a shallow depth. In worst case, can always build a collar to extend the mounting of the sub (raise it up) without jamming the sub into the backrests of your seat .
Looked at the pics and very creative use of space for amps etc. As long as they can stay cool in such a confined space... great ideas.
OK, seems like you have a pretty good head start on the enclosure parameters... now, let's see what subs can be found to meet this space you have. I'll have a look and see what's out there in the 300 RMS range and shallow depth, 8" subs.
Swez
Tray on 08/5/2003 16:44:26
Yeah, my amp is going to have to go under the front seat. Luckily there is enough space, that airflow should not be a problem.
I know that all of the subs above are 4" or shallower, but have not been concentrating on power requirements yet, as I figured I could run just about any range pretty easily. I was more worried about finding quality equipment that will fit my situation.
If I had the space, I'd probably already have gone with the Earthquake, as the 12 I put in my Blazer just amazed me. Unfortunately it most likely would require a large vented box to sound proper, and I don't have the room for the 1.2 cubic feet required.
The Bostwick, Polk Dx8, and CV HED8 all supposedly drop down to 20Hz, which would be great, but somehow I just doubt those numbers. Or at least that they can reproduce them at an audible level.
Swez on 08/5/2003 20:33:50
Have been doing some product searches on 8"s that might meet your criteria. It's not complete yet, but I have found a few that have the power handling and real close on the depth max mentioned.
Give me a private e-mail later this week and I will pass on what I have found to date. The one I like the best in terms of performance is from MA Audio.... but the depth is 4.6". Other than that, it fits the bill pretty close.

Relax_The_Mind on 08/6/2003 03:44:28
Correct me if Im wrong but i remember seeing subs that had that neodymium magnet or however you spell it. Making them super small and still moderately decent. Other than Lanzar and BOSS brand (only ones that came up in searches). If any higher end brand names make or carry them.
Out of your list the Polk Dx8s are the one of the only 8"s i ever heard that I was througouly impressed by. Specs by subs on your list the Cerwin Vega s8-4 Impresses me with high excursion than the most others.
Im also pretty sure if possible to raise the seats up an inch or so with spacers. Ive done that on the rear legs of a seat in a minivan to get an amp to fit under a brace that was there. hehe it actually leveled the seat better.

I didn't see this listed yet if it has been sorry. Check out the 8" A series from Elemental Designs. www.edesignaudio.com All the reviews I have heard on these have been good and many people have been very surprised with them for 8" subs. I have the 12" version and it is an amazing sub. Some of the best SQ I have heard from anysub.
Swez on 08/6/2003 08:27:31
Yes, I've been hearing very good things about these drivers fro, ED and heres a linmk to the 8" sub: http://www.edesignaudio.com/ep/overview/8Aoverview.htm
You may heve to write to them via email to find out what the dimensional specs are. Not listed in the parts of the site I looked at.
tech@edesignaudio.com
Swez
Tray on 08/6/2003 09:04:08
Hmmm,
Well, those look very impressive statistically.
Swez - here's the link to the specs
http://www.edesignaudio.com/ep/aspecs.htm
and the link to the box recommendation
http://www.edesignaudio.com/ep/abox.htm
Both look like it'd work well for what I'm working on. And the 3 year warranty is quite a bit more than I've seen with most other companies. The only downside is the $185 price tag for an 8.
RTM, yes it would be possible to raise the rear seat, but it would require relocating 16 bolts, fabricating new seat belt mounts, new LATCH mounts, and losing the folding functionality of the rear seat istelf. That was the first thing I looked into, as it was so easy in my 2000 supercab, I thought the supercrew couldn't be that much different. Boy was I wrong.
In my new Supercrew, I've located a spot that will be perfect for a pair of 8s, where I can still keep 100% functionality of my seats, the space under the seats, and everything else. The only problem is, I've never used, installed, nor even heard a setup running 8" subs.
I know it's going to be a huge change from the Earthquake DBX 12 that I just got for my Blazer, but that's a sacrifice I'll make any day to be driving my new truck.

Keep in mind, these are just pix of the driver side, and the passenger side has the same thing available.
As far as dimensions go, basically I'm looking at a wedge that starts at ~3 1/4 inches deep, and ends at ~5 1/2 inches deep at the bottom, which is ~17 inches down, of which, 5 inches are below the opening shown in the pics. I also have available nearly 23 inches of width to play with for each side, before I'd have to look at modding the framework (which I'm not going to do).
I built a little prototype out of a salad plate, a soup bowl, and some cardboard, and figured that if I stay at 4" of depth or smaller, I will have about 1/3 inch of clearance behind the magnet at the top, and just under one inch of clearance at the bottom. While not much, I am hoping this would be enough to allow proper ventilation.
RTM,
I wish I could use MDF, but I'm already to the point, where fiberglass is going to be my only option. Luckily I'll have the top, bottom and back, all supported by the steel frame, the front will be MDF, and depending on how wide I need to go, I may be able to make the sides MDF as well.
I wish I had a choice on the direction they'll be firing, but with the way things are looking, I am only going to have about 3 or 4 degrees of movement that I can play with.
Oops, almost forgot the amp links.

i did an install in my neightbors ford 150 '97 dunno if its the same or not, but there is plenty of room under the back bench to place amps. we just used the bench bolt for the ground so no drilling or anything was needed, we didnt custom any subs or anything, we just used his alpine bandpass out of his mustang gt, just swapped it he ever went anywhere in his truck. i think the truck sounds really cool with a system. all that cabin space and everyhting, made it sound really good.
compvr15s on 08/5/2003 15:39:26
oh my bad. didnt see that ya wanted to keep the room underneath the seats sry

It's probably similar to the 2000 SuperCab I had. In that I bought a lift kit for the rear seat, and had 2 10s running on the A7HC. Was metered at 152 on the dash, and I loved it.
Unfortunately the kids and wife hated it, and now that I am back around to a truck again (this time one that fits carseats), I need to keep the functionality, but want to make it a pleasure to drive as well.

OK Tray, thanks for spelling it out in very good detail and yes, I have seen pics of guys who glassed in the flooring area with a custom frame and it came out very well.
You have a very nice selection of amps and I agree that for power amps, the JBL makes good sense if you use a pair of 4 ohm SVC's. The other 2 channel amps mentioned are all well and good too. They could be most useful if you wound up using 8 ohm subs.
The hard part here, is finding a quality set of subs with such a shallow depth. In worst case, can always build a collar to extend the mounting of the sub (raise it up) without jamming the sub into the backrests of your seat .
Looked at the pics and very creative use of space for amps etc. As long as they can stay cool in such a confined space... great ideas.
OK, seems like you have a pretty good head start on the enclosure parameters... now, let's see what subs can be found to meet this space you have. I'll have a look and see what's out there in the 300 RMS range and shallow depth, 8" subs.

Yeah, my amp is going to have to go under the front seat. Luckily there is enough space, that airflow should not be a problem.
I know that all of the subs above are 4" or shallower, but have not been concentrating on power requirements yet, as I figured I could run just about any range pretty easily. I was more worried about finding quality equipment that will fit my situation.
If I had the space, I'd probably already have gone with the Earthquake, as the 12 I put in my Blazer just amazed me. Unfortunately it most likely would require a large vented box to sound proper, and I don't have the room for the 1.2 cubic feet required.
The Bostwick, Polk Dx8, and CV HED8 all supposedly drop down to 20Hz, which would be great, but somehow I just doubt those numbers. Or at least that they can reproduce them at an audible level.

Have been doing some product searches on 8"s that might meet your criteria. It's not complete yet, but I have found a few that have the power handling and real close on the depth max mentioned.
Give me a private e-mail later this week and I will pass on what I have found to date. The one I like the best in terms of performance is from MA Audio.... but the depth is 4.6". Other than that, it fits the bill pretty close.

Correct me if Im wrong but i remember seeing subs that had that neodymium magnet or however you spell it. Making them super small and still moderately decent. Other than Lanzar and BOSS brand (only ones that came up in searches). If any higher end brand names make or carry them.
Out of your list the Polk Dx8s are the one of the only 8"s i ever heard that I was througouly impressed by. Specs by subs on your list the Cerwin Vega s8-4 Impresses me with high excursion than the most others.
Im also pretty sure if possible to raise the seats up an inch or so with spacers. Ive done that on the rear legs of a seat in a minivan to get an amp to fit under a brace that was there. hehe it actually leveled the seat better.

RF makes a few 8's that may also fit this space requirement:

I didn't see this listed yet if it has been sorry. Check out the 8" A series from Elemental Designs. www.edesignaudio.com All the reviews I have heard on these have been good and many people have been very surprised with them for 8" subs. I have the 12" version and it is an amazing sub. Some of the best SQ I have heard from anysub.
Swez on 08/6/2003 08:27:31
Yes, I've been hearing very good things about these drivers fro, ED and heres a linmk to the 8" sub: http://www.edesignaudio.com/ep/overview/8Aoverview.htm
You may heve to write to them via email to find out what the dimensional specs are. Not listed in the parts of the site I looked at.

Hmmm,
Well, those look very impressive statistically.
Swez - here's the link to the specs
http://www.edesignaudio.com/ep/aspecs.htm
and the link to the box recommendation
http://www.edesignaudio.com/ep/abox.htm
Both look like it'd work well for what I'm working on. And the 3 year warranty is quite a bit more than I've seen with most other companies. The only downside is the $185 price tag for an 8.
RTM, yes it would be possible to raise the rear seat, but it would require relocating 16 bolts, fabricating new seat belt mounts, new LATCH mounts, and losing the folding functionality of the rear seat istelf. That was the first thing I looked into, as it was so easy in my 2000 supercab, I thought the supercrew couldn't be that much different. Boy was I wrong.
