I feel it would be the ideal location as its such a waste of space to have nothing in them lol... No need for a system in my blazer, i like the sound of the motor more 


I'm planning on running some Class D amps, and based on testing they are actually very accurate for average use, especially in a noisy ol' truck.
I've ordered them already.![]()
I don't see how a board conducts heat better than carpet. Mounting it directly to the sheet metal could help, but usually the bottom of an amp is just structural and the sides and top are the heatsink. Under the seat has to get more airflow than behind a side panel. The real question is whether or not your amp will have a problem back there under your usage conditions. Obviously enclosed amps without ventilation isn't something you would do for SPL competitions, but if your equipment works fine under the conditions you give it - it's a great space-saving and clean-up solution.Another note, when I did have some amps sitting on the carpet, they did actually heat up (in my opinion) more because the heat couldn't dissapate very well from the bottom side. Carpet is an insulator....so having it on a flat board behind the trim panel would be a better option.
Just my two cents......
True. But on the other hand, if your music source will be an iPod filled with 128kbps mp3s you may not notice the differenceYou will run into problem when using it as a mid and tweet amp. Class D amps kinda work like a switching power supply. They then filter out the high frequency switching before they send the signal out. This can make your mids and high sound muddled. That is why they are primarily used as sub amps. Subs dont play "highs" and muddled sound is less noticable for sub frequencies.

Sound is subjective. Best advice is to just try out what you intend to buy and then just buy what sounds good to you and dont worry about the rest.In my experience the speakers make all the difference. FWIW, here is the review for the amp I purchased:

There is always a trade off. You are trading extremely high efficiency for lack of overall sound quality. I love class A amps and had a pair of soundstream 10.2 and Picasso amps when I was younger. Right around 1400 watts but rated at 150w. They were cheater amps so you could compete in low power classes.
Anyway I enjoy my hearing to much now and would do a class D subwoofer amp and a class AB mid, highs amp no problem now.
Weird, I'm using Class D amps for the compete system, mids, highs and a seperate one for subs. Class D amps are just more energy efficient at what they pull and use as far as I was told and know, and the system in my Burb is far from quiet.
Nice set up
