    I have gathered all the components needed to upgrade my stereo. The speakers are all installed and the next phase is head units w/ maestro and a JL audio amp. I have the stock JBL system and know the amp for that is under the passenger front seat. Where should I put my new amp? Under the front seat or should install it behind the rear seat or under the rear seat. I suppose I would need shorter power and RCA runs if I go under the front seat and just a longer wire to the sub. I did but all the wiring needed at lengths to get the amp to the back wall of the truck if needed, including a 10 ft 9 conductor cable to run from the amp to the old amp location to pic up the speaker wires and remote wire there. Now I'm wondering if I dont even need that 9 conductor wire if I place the amp under the front seat. What is the best and easiest location to put my amp, including making adjustments to the amp controls such as gain and whatnot. I do not have any rear underseat storage bins to get in the way under the rear seat.

    Plan is to wire the left and right corner dash speakers off the head unit's front speaker outputs, the dual JL tweeter center channel speakers off the head unit's rear outputs. I will then power the door component speakers and sub off the amp. I came up with this idea when discussing my install with James at tech12volts and he thinks it's the way to go since I have a 4 channel amp.

    So where would you place the amp? My thought is under the passenger rear seat, but I see a lot of installs removing the OEM JBL amp and placing the new amp under the front passenger seat. Any and all ideas are welcome, pics too.
    Thanks

    Anybody? Maybe have pics of where you mounted your amp? I'm looking simple under front or back seat.

    I added my 2-channel amp for my sub under the driver's seat. I've seen a few installs that replace the factory amp with a new 4/5 channel in the factory location and looks really clean. I'm with you on keeping it closer to the front to limit the length of wire needed, but probably isn't a huge deal to run behind the back seat.

    @Pudge i have a kicker hideaway under my drivers seat and it’s as big or bigger than most amps would be. I also have my 4 channel amp and signal processor under the passenger seat. The amp is above the carpet with easy access to gain/crossover controls and the signal processor is under the carpet where the factory amp was since once it’s set there is really no need for access and it cleaner that having it visible in addition to the amp. Don’t have pics of the passenger seat but if beneath your drivers seat is free there is actually a flatter/larger area compared to the passenger side.

    My amps are under the front seats since I have the EPS storage unit under the rear seats. If you ever plan to add the under seat storage, I would install you amp under a front seat.
    Are you running new speaker wire or reusing the factory wiring? If reusing, you may want the amp under the front passenger seat, as that is where the factory harness is that feeds to the speakers.

    Front passenger seat should work well. Shorter power wire run. Speaker and rca wires under the center console. Remote wire under the drivers front dash and run it the rest of the waywith the power. Gound is kinda up to you.

    Are you running new speaker wire to the door speakers? If not, just buy the ********* wiring harness for their amp. It will plug into the factory wiring harness under the passanger side seat. You can cut off their molex connectors and connect to any amp you want. That's what I did.

    I also bought their amp rack too.

    I cut the carpet and removed the foam under the rear seats, placed my amps (2) in the cutouts and then flopped the carpet over the amps to cover them.

    No concern about heat due to amps being covered?

    There should be. They need some ventilation. At minimum this will shorten the life due to heat. May even cutout on warmer days.

    Not at all. The styrofoam actually acts as a heat reducer, and Im running JL amps, so, its quality as well. I have had it for 2 years this way and not a problem. They are running 2 JL 10s, JL c5 components (6 total speakers) in the front doors and Infinity component (4 speakers) speakers in the back doors

    That's what I was thinking. I would not be covering my amp with carpet thats for sure

    Heat reducer? I'd think it would just warm up when the amp does and with the carpet over the top you've got no air flow.

    The amps generate heat, the stryofoam will just help retain heat. Quality or not, need ventalation.

    When my buddy installed in his DC, he did the rear seat fold down mod, and then fastened some carpet covered plywood to the back wall and mounted all his amp and power distro back there in some of the “wasted space”. Living where’s I live in the winter if I have people in my back seat I don’t want water and ice sludge all over my amps if they were under my front seat. When I do my sub the amp will be on the back wall

    I was going to so that as well, but decided to go with the JL stealth bo with 10s. There was no room after that.

    The amp has a recommended temperature operational range. It would be interesting to get a temp with an IR gun after about an hour of use.
    The carpet covering would be my main concern.

    @DCB500 How does the kicker hideaway do as a sub? This seems to honestly be the perfect option for me without taking up the whole underside of the rear seat in my DC with a box and subs.

    Well funny you ask..... it is actually pretty descent and definitely a space saver and does a good job for fill in bass. It doesn’t pick up great on super low end frequency since it’s an 8” woofer but it does add a descent “thump”. I am actually in the process of switching over to separate amp and subs because I do want more of that low end so I will be getting rid of my hideaway if you are interested, just pm me if so.

    Well damn it....I also want more of the thump. Do you know what you're going to do for sub placement? I'd love to have a 'vertical' box that fits behinds our DC seats, but unfortunately I don't know if you could get the clearance for one.

    I ordered a box made to fit under the back seat that fits 2 10’s and then here is the amp and subs that I will be using.

    Kicker comp shallow mount
    Rockford amp that will be 800 watts the way it will be wired.

    Literally just got done taking out the hideaway and wiring up the new amp. Now just need the box!

    Not enough
    Sorry to revive an old thread, but I also have a JBL system that I'm replacing in steps. I was reading through some of your posts and saw that you were originally thinking about a small 2ch amp for the dash speakers, but that you decided to run them off your headunit, running the corners/sails off the fronts and the center dash off the rears. Are you still running the dash speakers this way? How does it sound? If you changed them, how are they wired now and how is the sound? What corner speakers are you running?

    Currently the only factory JBL piece left is the amp, but I have a 4ch amp (74wx4 @ 2ohms), a mono amp, and two JL 10"s and box waiting to be installed. I already replaced the speakers with ones from Tech12volts (Hertz uno for the doors, JL for all 3 dash), and the HU (Pioneer AVIC-8400).

    James said just to connect all the dash speakers to the front channels of the amp, but I'm not sure how well

    it would handle that. My friend that used to own a car audio shop said the center channel may not sound good since there is no center channel output from the HU, which we already know. He suggested running the dash speakers from the HU. He also suggested maybe splitting up the two center speakers and running one on the left and the other on the right channel, but didn't know if that would sound good. I've also read a little about running it as a mixed mono.

    Just looking for your insight before I order wire kits and pull everything apart.
