Aftermarket Amplifier placement ??

Well, the OME lift is sitting in the garage waiting for spring, so I'm going to do some long over due speaker upgrades. So far here is my plan.

Polk DB521 5.25 in the dash
Polk DB652s 6.5 in the Sound bar
Kicker 10CVT654 to replace the stock sub-woofer

I plan on running all speakers and the sub to an amplifier but am having troubles on deciding; A) What type of amp & B) Where to mount it ???

Somewhere that it's out of sight, yet if I mount it under the back seat I'm losing cargo space. (I fold my seat up/ take it out a lot for camping trips and general around town hauling) So what do y'all suggest? THANKS!!!

I have seen some mounted under the steering wheel in the space behind the plastic dash kick panel. also if you dont have the tuck forward seats I have seen some under the passenger seat. I also suspect there could be room under the glove box. These are the places I have seen them and I also plan to mount a component amp under my steering wheel.

I just had the same issue and ended up going under the back seat. Hated to do it but the amp I bought was way to large for anywhere else, bad thing is that mine was only a 50 watt amp and it was the size of a small wooden pallet.

Suggest a 4channel amp with a built-in x-over. Run the dash speakers to your radio. Front outputs of the amp to power the soundbar, then bridged the rear channels to power the sub. Under the rear seat is the most ideal due to size and proximity to run wires to sub and soundbar. Can't you just make a temporary,easily removable cover w/2x4's over the top of the amp to protect it for loading up camping equipment or hauling. It's really not taking up that much cargo space.

If you have the center console with the storage pocket or factory sub then I have seen a guy who has taken all that out and put both his amps in the leftover space. You wont be getting any big amps in there but at least its out of the way.

Skinny Pedal makes a really nice amp mount. I have seen some have trouble with shipment from him, but I had no trouble at all. it fits the Alpine PDX amps. I have been very happy with my small system.

Any pictures of your guys' step-ups? And I'm kinda getting the impression that I might need to go with 2 amps. 1 for the speakers, and 1 for the sub ??

I purchased the PDX-5 Alpine because it runs four speakers and a small sub. I am very happy. I need to find someone who really knows about this stuff to check over my tuning of the filters and bypass but to me it sounds great for a jeep system. I am an old guy so it is good enough. I recommend the skinny pedal mount. The amp is up and out of the way- not visable at all.

Any more audio junkies with ideas on my amp selection? I'll just be running the 2-4.25& 2-6.5 Polk speakers, & 1-6.5 kicker subwoofer (in the stock location)..

I have a Sony head unit running the dash and soundbar speakers and an amp powering a sub in the back, and it is plenty loud. I think the sony unit is rated at 17 amps per chanel.

First let me clarify, I am an avid car audio supporter, I sold and installed car audio for a living for many years. I will try to break things down as easily as possible but some things just come from experience, so heres my take on the situation:

Theres a huge difference between loud music and good quality music. I prefer both lol. The best start is a good head unit that can handle pushing the amps. Your system is only as good as its source. I always tell people "If you start with crap, then put 1000 watts in amps on it then you will end up with 1000 watts of crap" So a good source unit with 3 preamp outputs is necessary if you plan on amplifying all the speakers. 1 for the front, 1 for the rear, and 1 for the subs. You will not need alot of power since you will be pushing small speakers, I think that 6.5 kicker sub only needs 300w max then your interior speakers will only require 50w each to run very clear and very loud. Its actually better to overpower your speakers and turn the amps gain down so you dont get distortion, having everything run at max power is like running your Jeep at 5k rpm all the time, it works but its not good for longevity of anything. As for the amps you might consider something mentioned earlier in the thread, getting a good 4 channel amp, running 2 speakers (preferably the sound bar) off of 2 of the channels and then the sub off the other 2. If this is the route you will go then let me know and I will explain how to hook it up no worries.

as for suggestions:
Amazon.com: Rockford Fosgate PBR300X4 Punch BRT 300 Watt Ultra Compact 4 Channel Amplifier: Electronics is a great amp, not alot of power but then again you dont need alot, it would be just enough to run your setup. and it comes in a very small case which is convenient.

Amazon.com: MRX-V60 - Alpine 5-Channel Subwoofer Amplifier: Electronics is probably the best amp you could get for what you are running. its a 5 chanel amp, 4 for all your small speakers and 1 for a sub. just make sure you get the 2 ohm 6.5 kicker subwoofer. this makes all the difference when trying to get the most out of your system.

Sorry for the super long explination and hope I didnt overload you, if you have any other questions feel free to ask I'm more than glad to help.

Ive got a pioneer 760 watt amp, its probably a 14X8 and i keep it under the back seat. it honestly looks like crap back there with all of the wires. but its just too big to put under the seat or dash.

LilYeller, Thank you for your explanation! A lot of great info that I was looking for! So let me know what you guys think about this set up. All of it running off the amp that LilYeller suggested. I do believe in having a amp more powerful then the speakers and sub so it's not running with the gain turned all the way up.

Speakers: Polk Audio DB651s Slim-Mount 6.5-Inch Coaxial Speakers
: Polk Audio DB521 5.25-Inch Coaxial Speakers

Sub : Kicker 6.5" CompVT Car Subwoofer 2 OHM 10CVT652

Amp : MRX-V60 - Alpine 5-Channel Subwoofer Amplifier

Looks like with this Amp I should be able to use Skinny Pedal amp mount ? (maybe)

To the heart of it all.. the head unit. I currently have the Sony CDXGT540UI, is this powerful enough with the right ports to be able to accomplish what I'm looking to do? If not.. what do you recommend?

The help with this has been awesome!!! Thank you guys, soon enough the neighborhood will have another reason to complain, lol!

Thats a decent head unit and it does have all the preouts that you will need to run that amp. I didnt see if it had subwoofer level control but in a Sony its almost a guarantee. Keep that HU and you will have a good system in no time.

Awesome! Thanks for all the help! What type of wiring do you suggest? I know I need a good power cable to the battery... what do you suggest and where do you suggest running through the firewall? I was already planning on running new wires to all the speakers, what type do you suggest on them? Thanks again for all the help. It's been terrific!

anytime! As for the power, you could get an 8 gauge power kit and it would work perfectly. There are plenty of grommets for you to run that power wire into the engine bay of the Jeep, find one, check both sides before you cut or drill a hole anywhere, and push that power wire through. As for the speaker wires, its not really necessary to replace them. The factory wires are big enough to handle the power that you will be pushing. If you are hell bent on changing them then go with a 16 or 14 gauge wire, Im not exactly sure what size wire comes from the factory but I can tell you its big enough to handle my Eclipse 4ch amp with no issues.

I have Polk db's front and rear. 10 Alpine sub and Alpine 5 channel amp. Sound quite good. Been doing the car audio thing 4 20+ years. Mounted the amp under rear seat. I also camp and remove the rear seat. What I have done is cover the amp with a plastic 2 liter tray from the grocery store. Attached with velcro when seat is out. Not water proof but protects amp and lets it breathe. I agree with a previous poster, the heart is your source. I happen to use a kenwood excellon. Keep in mind, it is a jeep. Never gonna be a concert hall. Front stock speaker position sux but it can still sound good. Sounds like u have a plan. Happy jeepin

I dont know if that amp will fit but the PDX-5 fits perfect. You maybe could get the measurements of the alpine site. The PDX-5 fit the predrilled holes in the skinny pedal mount. By the way the skinny pedal mount is worth every cent. When you get the mount it looks like ..."really, that's all ?" but when you put it in and realize how it fits in the space you will realize it looks more easy than it is to make.. if you know what i mean.

And for what it is worth I got the 2ohm Kicker sub and made a box to go into a tuffy.
