For christmas im getting a 15inch sub cuz i want a louder set up then what i have now with is two audiobahn 10's in a sealed box and an 1800wt pyramid amp but ive been looking around and i found an MTX T8154A and that looks like it would be my best bet but im also looking at a fosgate p2 but not happy with it only being able to handle 250wts rms and i found an audiobahn 15 but its dual 6 ohms and im not sure how that would work with my amp cuz my amp is weird and cuts out unless i have it set up perfect but im wanted a 15inch sub tuned low in a ported box just need to find a good sub

Actually you need to first find a good amp before a better sub. The amp you have now is kind of a cheaper brand and it wont matter what sub you hook up to it. You could hook up a $1000 sub to it and it will still sound bad. Pyramid extremly over exagerates their power output. They will rate them with somthing crazy like 18v (or somthing like that) input to acheive the 1800watts it says on the top of the amp. You are honestly puting nowhere near that number with that amp.
If you can give us the model number, rms watts, impeadence etc of the subs you have now I'm sure someone here can show you some amps at a really good price that will bring those two 10" audiobahns to life for you.
I dont mean to put down your gear, but the amp is the weakest link in your system and it is probably whats causing you not to be happy with how your system sounds at the moment.

PS at www.ikesound.com they have an Alpine MRD-M301 class D sub amp that puts out 350w rms that I am going to be personally buying for only $140. I will be using it to power a single 12" Alpine Type R in a sealed or ported enclosue (i have two boxes, depends what kind of bass im in the mood for lol) And when this sub i have is in its vented box its almost too loud to use in my car as a daily driver and its only 300w rms.

uochronos on 10/20/2004 02:06:46
15's well be louder the bigger cone area makes them more effiecient and get louder, they wont get punchy bass really to get punch you need 10" sub or a 12" sub.
kole audio makes some good subs. so does diamond audio, and resonant engineering.
the adire subs though may look like some crappy homeaudo woofer but trust me they out perform most subs i haev heard.
Victor on 10/20/2004 06:00:13
I wud agree with uochronos... I would personally opt for 2 x 12" subs rather than a 15" .. cause 12" have a better transient response and when in a ported box two 12" will get louder and punchier than the 15".
yet if you would like to go for a 15" here's the one from cerwin vega .. one of my friends just bought it and is quite happy with it..

LC1 on 10/20/2004 18:20:18
All the subs mentioned are good choices, except you should stay away from Pyle, Legacy and Audiovox. There is a reason why they are cheaper then 20 feet of 4ga power wire, you get what you pay for lol.
I'd go with the Type R, I currently have a single 12" Type R like I said above and its a GREAT sub for what I paid for it.
-Jay-
P0werLifter on 10/21/2004 01:53:36
Yah i agree with LC...stay away from Pyle, Legacy, and AudioVox... Personally i havnt heard much about the PowerAcoustik FBX or Fubar series subs, but i have a pair of MOFO 12s and they POUND...takes alot of power to run these effectively though.
Remember, in order to get the most out of any subwoofer, it needs to be in the correct enclosure, You can have the nicest high dollar subwoofer in a crappy enclosure and it will sound like $hit, on the other hand if you have a really crappy sub, but have it in a excelent enclosure, it will sound good. Its all in the install.

How is your car electrical wise? Have you upgraded all the neccessary parts such as your Alternator, battery, Wires and grounds? In order to run a high wattage system this is going to take alot of power.
A typical automobile runs a <100ampere alternator, and it takes 50-60amperes to run your stock electricals (IE Fan, AC, Heater, Defroster, Etc) leaving you with around 40-50amperes to play around with, without having to upgrade your electricals.
Not talking crap or anything, but pyramid really over rates their products so i have my doubts about how much wattage your system is really putting out right now. If infact you havnt upgraded your electricals, i forsee major issues arising if you try to run a over >600watts. If you have minor light dimming it can be fixed with a simple battery upgrade, but if you have major issues then an alternator + battery + new wiring will run you + >$600 to support your systems needs.
Heres an article that will go in depth on charging basics

i know that my amp is prolly only putting out about 300 or 400 watts so thats why im prolly just going to get a Fosgate P1 or P2 (200-250wts rms) it would push one of them pretty good or maybe if i got a sub that was 500wts rms 1000wts max do u think that would sound good
P0werLifter on 10/21/2004 12:28:53
A 500watt RMS system will pound nicely and sound good also. Not only that, but running 500rms will not have a huge impact on your electricals so you should be fine. Personally i havnt heard the new P1 or P2 but they look pretty good. You should be happy with the way it sounds. Just remember. a 15" driver will take a larget box on average to perform well.
How much area do you have to work with?
-Jason
uochronos on 10/21/2004 13:32:42
i agree trhe amount of upgradeing to get a 2000watt rms system to run would be extensive. i have put around 500$ in electrical upgrades to get my 1600watt rms system to run.
a 400-500watt sub can defiantly pound hard remember if both subs have the same efficiency rating then giveing a sub 2000watts compared to 500watts only gains you 6db or so more volume.
if you go with a proper ported box for the sub you choose and give it 300-500watts rms you well get a very loud systems.

the only reason we suggest building it yourself is a custom box from a shop well cost 150-400$ maybe more mattering how fancy you get... and you can buiild the same box for well under 100$. its also nice to be able to change it if yyou want. i have built 4 boxes for one set of subs i the past year. tweaking it to my tastes.

LC1 on 10/21/2004 18:27:22
Just a thought/question, you guys always say doubling your output only nets 3db louder and its not that noticeable. I understand the physics behind why this is, but as for it not being noticeable, I dunno. I went from a 12" Alpine Type S that was 200w rms to a Type R that is 300w rms. Therefore only giving me one 1db extra for the 100w more. The results were amazing, that a 100w more could sound that much better and put out so much more bass. Thats why I don't understand why you say going from 300-600w or 600-1200w isnt that noticeable. If my extra 100w sounded that much better, then i could only imagine how much an extra 300w or 600w more would sound.
Just a thought, I know the mathematical reason for the 3db but the way it sounds to my ears is different. Also it isn't always how much louder it goes but how much more bass or sound quality it puts out if you are talking aobut mid-high range speakers.
-Jay-
Victor on 10/21/2004 18:32:04
who said its not noticable.. it is of-course.. but after a certain limit of say 125dB -130dB that minor a change of 3 dB will not be noticable.. at lower decibles that change is of-course noticable..
Faded on 10/21/2004 23:35:16
i cant wait tho going from 2 300wts max audiobahn 10's in a small sealed box to a 2000wts rms 4000wts max audiobahn 15 in a huge ported box its gonna be awsome!
P0werLifter on 10/22/2004 01:54:35
Faded....have you decided on a sub? are you going to go with a 2000watt RMS system? Plz consider the money that will be involved with electrical upgrades, wiring, amplifiers that will be required for this system. If you do not upgrade your electricals prior to running this amount of wattage,,,you are doomed to be stranded somewhere with a dead battery and a toasted alternator.
LC...when we say doubling your wattage will ned a +3dB gain and that its inaudiable to the ear, we are talking anything over >120dBs +3dB is not going to be heard. At the lower dB's you can notice.

i have a 1200watt amp faded for my subs i have it set at around 500-700watts rms and trust me that bumps hella hard.
and btw LC1 you wnet from a type S to a Type R ya you onyl gave it 100watts rms more but you also went to a more effiecient sub and a sub with a larger xmax. when we are talking about only gaining 3db thats say if you have a alpine type X and you only give it 500watts rms you well only lose 3db of volume from if you gave it a full 1000watts rms. inbetween differnt subs you haev to compare efficiency and xmax as well.

P0werLifter on 10/22/2004 02:43:57
Personally, id go with the MOFO because i have a pair of MOFO 12's that im getting ready to take out for my 15" XXX but they pound. I have 900watts RMS running to each, only problem you might see is feeding enough wattage to the single 15 as i believe they are 1200watts RMS but you can get by with less.
swez on 10/22/2004 08:45:05
There is so much detail (long threads) in this topic, hard to make out what the new plan actually is anymore.
Can you help by summerizing your overall goals, budget and the performance level you are shooting for in a new post? I am just plain lost with all the details and no real plan on component choices, amping power and sub choice(s).
FYI: It is true that if we double the power from the amplifier, we get a +3 dB increase in SPL. At moderate SPL levels (under 110dB), a 3 dB boost is very discernable. But, once we get past ~120 dB of SPL, a 3dB boost is very minimal.
Also, driver efficiency ratings, enclosure design and size of the
woofer(s), all play a roll in the overall outcome. For pure SPL Bass performance, Ported/vented or BP are excellent for high SPL Bass and best performance below 80-100 Hz.
If you want more punch and definition, enclosed MB driver(s) with adequate power and sufficient SPL capability will help. Here, an 8" MB design will definitely help bring out the punch we lose in most sub box designs. Nice thing about MB, it's still pretty much Omni-directional to about 300 Hz. So, location of the MB drivers are pretty flexible. Rear decks are very good and so are rear door mounts. The main thing, adequate power and an enclosure, make a huge difference in MB performance.
Hope this helps,
Swez

I wud agree with uochronos... I would personally opt for 2 x 12" subs rather than a 15" .. cause 12" have a better transient response and when in a ported box two 12" will get louder and punchier than the 15".
yet if you would like to go for a 15" here's the one from cerwin vega .. one of my friends just bought it and is quite happy with it..

All the subs mentioned are good choices, except you should stay away from Pyle, Legacy and Audiovox. There is a reason why they are cheaper then 20 feet of 4ga power wire, you get what you pay for lol.
I'd go with the Type R, I currently have a single 12" Type R like I said above and its a GREAT sub for what I paid for it.

Yah i agree with LC...stay away from Pyle, Legacy, and AudioVox... Personally i havnt heard much about the PowerAcoustik FBX or Fubar series subs, but i have a pair of MOFO 12s and they POUND...takes alot of power to run these effectively though.
Remember, in order to get the most out of any subwoofer, it needs to be in the correct enclosure, You can have the nicest high dollar subwoofer in a crappy enclosure and it will sound like $hit, on the other hand if you have a really crappy sub, but have it in a excelent enclosure, it will sound good. Its all in the install.

my limit shot up to 200 today cuz i got a job so i was looking at this audiobahn sub my friend really wants me to get it but im scared cuz my amp is crap and this sub is 2000wts RMS!! and so im scared my amp isnt going to push it so its gonna sound like crap until i got a new amp but i was looking at a http://www.cardiscountstereos.com/catalog%20page.asp?Product+%23=MOFO15 thinking that my amp would prolly make that one pound and when i get a new amp it would be just right
heres the audiobahn
http://www.cardiscountstereos.com/catalog%20page.asp?Product+%23=AW1508Q
wish i wouldve bought a better amp in the first place
Faded on 10/21/2004 01:59:23
but if i got the audiobahn whenever i did start looking for a new amp i could get a huge one

How is your car electrical wise? Have you upgraded all the neccessary parts such as your Alternator, battery, Wires and grounds? In order to run a high wattage system this is going to take alot of power.
A typical automobile runs a <100ampere alternator, and it takes 50-60amperes to run your stock electricals (IE Fan, AC, Heater, Defroster, Etc) leaving you with around 40-50amperes to play around with, without having to upgrade your electricals.
Not talking crap or anything, but pyramid really over rates their products so i have my doubts about how much wattage your system is really putting out right now. If infact you havnt upgraded your electricals, i forsee major issues arising if you try to run a over >600watts. If you have minor light dimming it can be fixed with a simple battery upgrade, but if you have major issues then an alternator + battery + new wiring will run you + >$600 to support your systems needs.
Heres an article that will go in depth on charging basics

i know that my amp is prolly only putting out about 300 or 400 watts so thats why im prolly just going to get a Fosgate P1 or P2 (200-250wts rms) it would push one of them pretty good or maybe if i got a sub that was 500wts rms 1000wts max do u think that would sound good
P0werLifter on 10/21/2004 12:28:53
A 500watt RMS system will pound nicely and sound good also. Not only that, but running 500rms will not have a huge impact on your electricals so you should be fine. Personally i havnt heard the new P1 or P2 but they look pretty good. You should be happy with the way it sounds. Just remember. a 15" driver will take a larget box on average to perform well.
How much area do you have to work with?

uochronos on 10/21/2004 13:32:42
i agree trhe amount of upgradeing to get a 2000watt rms system to run would be extensive. i have put around 500$ in electrical upgrades to get my 1600watt rms system to run.
a 400-500watt sub can defiantly pound hard remember if both subs have the same efficiency rating then giveing a sub 2000watts compared to 500watts only gains you 6db or so more volume.
if you go with a proper ported box for the sub you choose and give it 300-500watts rms you well get a very loud systems.

Faded on 10/21/2004 14:15:03
oh im planing on putting the sub in a huge low tuned ported box
P0werLifter on 10/21/2004 14:34:10
K sounds good, are you planning on building this enclosure yourself? Id reccomend it, great learning experience and its great to see..and listen to your work =) we can help you as long as you give us the proper information GRIN

lol kool but ive tried doing stuff like this before i think im gonna get my local audio shop to build a custom box for me so i dont have to go out the next day and fix it
Faded on 10/21/2004 15:02:40
and plus im not gonna get the sub till christmas
uochronos on 10/21/2004 15:11:49
the only reason we suggest building it yourself is a custom box from a shop well cost 150-400$ maybe more mattering how fancy you get... and you can buiild the same box for well under 100$. its also nice to be able to change it if yyou want. i have built 4 boxes for one set of subs i the past year. tweaking it to my tastes.

LC1 on 10/21/2004 18:27:22
Just a thought/question, you guys always say doubling your output only nets 3db louder and its not that noticeable. I understand the physics behind why this is, but as for it not being noticeable, I dunno. I went from a 12" Alpine Type S that was 200w rms to a Type R that is 300w rms. Therefore only giving me one 1db extra for the 100w more. The results were amazing, that a 100w more could sound that much better and put out so much more bass. Thats why I don't understand why you say going from 300-600w or 600-1200w isnt that noticeable. If my extra 100w sounded that much better, then i could only imagine how much an extra 300w or 600w more would sound.
Just a thought, I know the mathematical reason for the 3db but the way it sounds to my ears is different. Also it isn't always how much louder it goes but how much more bass or sound quality it puts out if you are talking aobut mid-high range speakers.

Victor on 10/21/2004 18:32:04
who said its not noticable.. it is of-course.. but after a certain limit of say 125dB -130dB that minor a change of 3 dB will not be noticable.. at lower decibles that change is of-course noticable..
Faded on 10/21/2004 23:35:16
i cant wait tho going from 2 300wts max audiobahn 10's in a small sealed box to a 2000wts rms 4000wts max audiobahn 15 in a huge ported box its gonna be awsome!
P0werLifter on 10/22/2004 01:54:35
Faded....have you decided on a sub? are you going to go with a 2000watt RMS system? Plz consider the money that will be involved with electrical upgrades, wiring, amplifiers that will be required for this system. If you do not upgrade your electricals prior to running this amount of wattage,,,you are doomed to be stranded somewhere with a dead battery and a toasted alternator.
LC...when we say doubling your wattage will ned a +3dB gain and that its inaudiable to the ear, we are talking anything over >120dBs +3dB is not going to be heard. At the lower dB's you can notice.

i want a sub that bumps well enough with my amp now but i cant still upgrade not neccesarily to a bigger amp but a better amp and not be afraid my sub is gonna blow
uochronos on 10/22/2004 02:36:08
i have a 1200watt amp faded for my subs i have it set at around 500-700watts rms and trust me that bumps hella hard.
and btw LC1 you wnet from a type S to a Type R ya you onyl gave it 100watts rms more but you also went to a more effiecient sub and a sub with a larger xmax. when we are talking about only gaining 3db thats say if you have a alpine type X and you only give it 500watts rms you well only lose 3db of volume from if you gave it a full 1000watts rms. inbetween differnt subs you haev to compare efficiency and xmax as well.

Faded on 10/22/2004 02:39:01
wich of those two subs up there you think i should prolly go with ?
P0werLifter on 10/22/2004 02:43:57
Personally, id go with the MOFO because i have a pair of MOFO 12's that im getting ready to take out for my 15" XXX but they pound. I have 900watts RMS running to each, only problem you might see is feeding enough wattage to the single 15 as i believe they are 1200watts RMS but you can get by with less.
swez on 10/22/2004 08:45:05
There is so much detail (long threads) in this topic, hard to make out what the new plan actually is anymore.
Can you help by summerizing your overall goals, budget and the performance level you are shooting for in a new post? I am just plain lost with all the details and no real plan on component choices, amping power and sub choice(s).
FYI: It is true that if we double the power from the amplifier, we get a +3 dB increase in SPL. At moderate SPL levels (under 110dB), a 3 dB boost is very discernable. But, once we get past ~120 dB of SPL, a 3dB boost is very minimal.
Also, driver efficiency ratings, enclosure design and size of the
woofer(s), all play a roll in the overall outcome. For pure SPL Bass performance, Ported/vented or BP are excellent for high SPL Bass and best performance below 80-100 Hz.
If you want more punch and definition, enclosed MB driver(s) with adequate power and sufficient SPL capability will help. Here, an 8" MB design will definitely help bring out the punch we lose in most sub box designs. Nice thing about MB, it's still pretty much Omni-directional to about 300 Hz. So, location of the MB drivers are pretty flexible. Rear decks are very good and so are rear door mounts. The main thing, adequate power and an enclosure, make a huge difference in MB performance.
Hope this helps,
Swez

ya know what im getting to where im not sure wich sub to get wich would be best pushed by my amp, wich would sound the best, wich would be the best sub to go with in the long run but i have a pyramid 1800wt 4channel amp it does sound like a really crappy amp but it does push pretty hard and i need to take my time and look around to see wich sub would be the best to go with my amp and my car but right now i have the flew so...im sick....but i really really do appreciate all of you this site is awsome and i will prolly get back on in a couple days but till then im sleeping...
pyramid 1800wt 4channel amp 4ohms minimum backseats taken out of car what sub would all of you get if you were stuck with my setup ?
