okay, ive got a sony xplod 1000w amp, (xm-1652z) and im trying to install it with a pair of subs in my trunk...

i know i have power, i know i have a good ground, and i know that im getting resistance from the amp... im going crazy trying to figure it out...

on the amp, there's three terminals.. one says 12v one says ground, and another says "rem" ...the guy at circuit city said that it was a remote wire, but i dont have a remote for it, so i just left that one alone.. was the guy wrong? do i need something there? please help me, im so confused...

The REM lead is a 12 volt trigger voltage that tells the amp to turn on/off when needed.

Most aftermarket HU's have this feature. Stock HU's do not and we have to add a wire to turn the amp on/off either manually or tappin off the ACC/IGN circuit in the fuse panel. If we don't feed the REM a +12 volt signal, the amp will not turn on... period.

The amp needs 3 critical power wires to work:

1. B+ is 12 volt power off the battery terminal
2. A good body ground
3. The REM lug needs a +12 DC voltage to turn the amp on/off

Say more about your install so we can guide you along.

alrighty then,
i have a pioneer HU, (DEH-mp2900)

ive got the first two of the three you said i needed, what i dont have is the "REM lug"

....what wires would i need to run where to get this working right?

thanks

Good, your Pioneer HU has a REM trigger line and the amp mentioned has a REM wiring post/lug. All you need to do is extend a line from the HU to the amp and it will turn the amp on.

Review the install manual for this HU. It may have a power antenna and REM feed line in the main harness. You'll want to use the REMote line, (Blue w/ White stripe or solid blue?) to connect to this amps remote power terminal. Once that is done, the amp should fire up just fine.

AWESOME!

I pulled my HU back out, and tied a wire from my "REM" lug into my ACC behind my HU. Works great!

I'm so pleased with this audio forum.. It's unlike any other I've seen on the web.. You guys are VERY helpfull!

I'm not sure if you remember me or not, but I posted a question about my car at the end of 07' and you guys guided me along they way...

Now, (a few months later) I have a new pioneer HU, with two 12'' JBL's and a 1000w Sony XPlod amp.. I've got two 12" speakers strapped into my backseat by the seatbelts (home audio speakers wired into my back speakers) Because who needs backseats? LOL

Then I have a set of mids, and two tweeters for each back speaker aswell.. So far, so good.. I'm pretty happy with my system considering it only costs about $350 total.. (the car only costed me $250 Hehe...)

Thankyou so much, I'm glad I found this site, I'll be sure to reccomend it to anyone who asks me for help...

Hehe, reminds me of when I started........What JBL subs are you using? I have been extremely satisfied with my GT5's.

Put up some pics of this, I have no doubt that it could sound pretty good, bet those house 12's put out some killer midbass......And I agree on the backseats, who really needs them?? If they want to ride that bad, they can sit "speakers"!


swez on 06/23/2008 20:49:52
Yes, I remembered your screen name and am glad your plan worked. It turns on the amp as soon as the car is in ACC/IGN mode. If your HU is not on, you may hear a thump when you turn the HU on. Other than that, it's OK as is.

Awesome! Thankyou so much. You have helped me more than I could have imagined, and I'm more than satisfied with it!

I'm going camping tomarrow, and I need the room in my backseat for camping gear and fishing rods.. (I dont like letting them ride in the trunk.. Not that I have Much room to start with) So I had to take the 12's out of my backseat, I've still got the subs in the trunk, but all I have right now for speakers in the back are some substitutes I threw in there just to balance the sound out..

I do have a question about the LPF... (I'm guessing it's the Low Pass Filter) What excactly does it do for my subs, and where should it be set at? I think it's at 1v - (BTL)... (whatever that means) And above everything it says 80 hz.

I can understand some of this stuff, but right now it seems like giberish to me...

I think it sounds alright where it is, but it doesnt seem like it hits as hard on the higher bass notes.. It could just be because they are 12" subs, and they dont have the impedence for those notes, but I dont exactly know what I'm talking about, so an expert opinion would help a lot..

And I'm not sure how to get a picture of it on here, but I will do my best to show you what I've got...

SQLThump on 07/2/2008 09:21:37
Create an account at Photobucket, and upload digicam pics to there. After that, you can post direct links to pics or albums.

No more 12's in the backseat? screw gear room....

Your LPF is for eliminating high frequency and midbass signal from playing through your subs. This will reault in celaner, more responsive bass, if you find your upper bass is suffering, you can elevate the crossover point slightly in order to get a little better response, if your amp's crossover is adjustable.

Try around 100-120hz, but if you find a bit too much midbass, or any vocals other than a male vocalast yeling a word that starts with "P" or "B," (this can cross into sub frequencies crossed over very low) than lower it to a point that this no longer occurs.

Hehe, camping huh? Sounds like a great adventure pending and hope you get good weather too.

This is a pretty small car, so your stowage space is minimal. If you can live w/o the bigger boxes for a few days, leave them home.

Another option, if you need more space would be to install a trailer hitch and rent a small covered U-Haul trailer for your camping gear. If your lugging a small boat on a trailer this trip, pack the boat with gear and put a cover over the boat. I did that a few years back and it all worked out great. It rained on the way home, but all our gear stayed dry the whole way home and it was a great time in all.

Fishing was very good on that trip... some nice LM Bass were caught, but my partner was not so fortunate. She got skunked the whole trip. That was a bummer as I would have loved to see her tag into a few nice fish and watch the battle from the tiller. Oh well, she was a good sport about the whole thing and we had a great time anyway.

Swez

PS Ever try fly fishing? That takes fishing to whole new level. It's really a kick to hook and land bass, trout, pike or other larger fish species. Yeah, it's an expensive sport to get into, (gear-wise) but when one latches on to a bigger fish, their in for a good, long fight on light leaders. (3-6 lb test leader) The longer rod helps fight the fish into submission rather than brute force to haul them in fast on 12 lb test line. Either way, it's a real thrill.

SQLThump on 07/2/2008 10:42:48
ahhhh....fishing, have had to make several backing out explanations that fishing trips turn into drinking trips for me if a boat is not involved, and since none of us got any boats......I have to decline.....I have never caught a fish off a shore in my life, only boats....

swez on 07/2/2008 13:29:05
Would think the local streams and esturaries in CO would be excellent for stream fishing. But are they close enough to drive to to enjoy?

Some research and analysis would give some direction. The CO/DNR sites would be a good place to start. Once one knows the hot areas, it's all about time in the water, trial and error and what works in the areas close to home.

Here in SE MI, we have plenty of lakes, ponds and streams to fish. The bigger fish are found in small lakes. We look for cover, weedbeds and other stuctures that lure the small fry. The big boys are always lurking in these areas, waiting to pounce.

One bait that seems to produce on a regurlar basis, is the Texas style rigged rubber worm. You can add a spinner type blade to attract more attention via vibration or use a fly worm. Either way, this produces the most action on a consistant basis. My bother is more of a dry/wet fly "purist". But when the "bit is light", a worm bait often proves to be the best choice. (Spinning, jigging, fly or bait casting)

Oh, my brother and our freinds really fish it up, but I lack the interest and skill to really enjoy it. Kept trying until I was about 20, and got sick of my freinds nailing them, and myself never bringing anything home, so at this point I started lugging arounf a tackle's weight of beer.

Now I don't drink hardly at all, so standing in the sun for hours while there are plenty of other hobbies to occupy my time seems less and less appealing.

Would much rather work on an audio project, play a video game, go for a cruise, see freinds and cook. If they bring some freshly caught fish, all the better!GRIN

We do the most fishing in the latter PM and after dark. They are ready for the bug hatches that come at this time of the year and under the cover of darkness, fish are less shy and tend to come out of dense cover and move, around more and are more aggressive.

There seem to be peak feeding times and figuring them out is the key to consistant catches. Here in MI, things begin to happen just before sundown and maybe continue for about 2 more hours after dark right now. A Lot depends on the weather conditions, solunar swings and barometric pressure changes.

Low pressure system seem to be most productive. But if we see swings from High to Low and High Barometric numbers in a short period, (2 days or less) this often puts fish on lock-jaw mode until the weather systems stabilize for at least 48 hours. Having a boat helps a lot as some fish just go deep when this happens. If one has a boat, they can go deep. But if fishing rivers, ponds and lakes, the shore and wade fishing tactics are limited.

Even on a rough night out and few to no fish are caught, just getting out is what counts. Last week, my brother went out for the night and nailed 30+ fish on a fly rod in 2 hours. I went out to the same place the next night when a cold front was moving in and caught 2 tiny fiddies in all. "Cold Front Rules" apply and when they come in, fish naturally turn off.

Finally, there are nights we go out and we both catch lots of fish. There are also many trips when one gets a bunch and the other gets a few or zip, nadda, zilch. It flips too. Dale has been an avid fly fisherman for 25 years. (His prowess with a fly rod is like watching poetry in motion) Yeah, he's guide level skilled. I've been into this side for ~4 years and still have much to learn. But even with the experience difference, he's been skunked and I held the hot hand and visa-versa. It did not matter either way though. The "brother-bonding" times are far more important than the catch. As one get older, you'll know what I mean... really!

Swez

PS When the wind is up and we have to use spinning gear only, I have the edge most times. After 20 years in that realm, I have the extra experience, tackle and touch. Again, it does not matter. The fact we got out for a few hours together, is the goal. Our Dad taught us the basics and to love the great outdoors. I wish he was still around to share these experiences with us. He passed away before we could all share theses moments together. But his legacy is still here, just as he and his brother shared when they were younger. How cool is that?

SQLThump on 07/2/2008 18:28:58
Don't get me wrong, I love thr outdoors, thats what the cruises and occaisonal camping trips are for. Outdoor hobbies can be expensive though, and need to work on my outdoor gear supplies a little besides firestarting apparatus and hunting knives though. I remember a very ellightening 120 page book I read called "How To Take A **** In The Woods," which made me pretty environmentally savvy about the ol' camp latrine. Need to invest in a good tent and a better sleeping bag than my old army "mummy bag" that is beginning to smell like 18 years of "SQLFunk."

Do feel the brotherly bonding though for sure. I don't really go with my real brother, but the adopted brother is agreeable, and does not share the desire to fight so much, so we generally have a good time, as long as enough food is packed.

I do live in a pretty urban area, and with price of gas, haven't yet made any seroius outings.

swez on 07/3/2008 00:52:24
Yep, I hear ya on the "live in an urban area and gas prices stuff too". It's put the pinch on our number of outings this year and we share the gas expenses depending on who drives. That's only fair and makes it more doable.

Fortunately, we have a number of good sites to hit as desire. Most are 25-45 miles out. (One-way) If the fuel prices were not so high, would love to head north and try the trout streams that are very abundant and famous for the water quality and fish they produce. But that's a 250 mile trip out, another 150 miles to try various rivers and streams and then 250 miles back to home base. That's roughly $150.00 in fuel cost plus food and lodging.

Neither of us have adequate camping gear at the moment, or the time to break away for 3-4 days right now. So, we just fish the local areas and try to out-fox the big ones we know are out there. It's not all that bad to do the local jaunts a few times a week. Heck, 30 miles west and we're out in the boonies. So, we do that most often.

Anyway, we enjoy leaving the urban jungle for the solitude and break away from the hords of weekend warriors. Our favorite sites are pretty remote and we don't have to contend with canoer's, kiaker's and crowded fishing sites. It's great to be out in the wild after dark. All the daytime critters are sleeping and the night critters are out in abundance.

We often see deer, racoons, possum, muskrats and beavers. On a warm night and good hatch, the air is thick with bats. Dale snagged one last year as it dove on his fly and his fly got stuck in the bat's wing. Strange huh? (He caught a bat on a fly rod???)

Yeah, I've had a few hit the line when casting, but never snagged one. It's the strangest thing too... one minute we're plumbing the river for fish, pull up the line a reset for another drift and wham, the line stops in mid-air and starts to take off in a wierd direction... that's a bat for all right.

Anyway, if the weather holds, we may head out tonight and see what's cookin. It's a great sanity break from the daily grind.

Swez HAPPY

Yes, I'm sorry, I had to take them out.. The bass sounds a little better after I moved the big speakers out of the way... But I do miss them.. They're still in my room though...

I think I can get pictures of them on here.. I'll keep trying, They'll be on myspace, but I dunno if you have a myspace.. I dont blame you if you don't haha...

Yeah, I've tried flyfishing, I just don't have the income to do it.. I can barely afford fishing trips as is.. But I do enjoy Fly fishing..

I'm hopeing to get a hatchback soon, and getting rid of my old junker.. So I will have a little more room, and the subs can ride in the car with me, so I can turn the volume down.. hehe...

All is good for now though, I have friends with pickup trucks, so we can pack the gear in his truck, and still have room for the boat :P

SQLThump on 07/10/2008 17:23:52
Volume down???? Ok then...GRIN

I got a myspace. Put your address up here and I'll hit you up.

gotsomechange on 07/14/2008 12:36:52
Ha ha, I know whatcha mean about the volume.. But when I first got my subs, my ears hurt for three days straight.. So uh.. I've turned it down a little bit...

And about the myspace.. Just go to: myspace.com/kodylaws
I think I fixed it so that anyone can view my profile, but if not than add me... I'm putting the pictures on there right now..
