ok, i am replacing my door speakers and my backseat speakers. (Infinity Kappas) I already have 2 subs and 1 AMP. I think I am gonna get an MTX 4-channel. I don't know where to mount that AMP. On the seat is not an option. Maybe under the seat, but I wanna be able to access it. Anyone else have a similar setup? Where did you mount your amp? Pics if possible. I am also OCD about wiring, all the wires for my sub setup are hidden.
Thanks!

i mount my amp on a circular board. I place it on the spare tire.

 

mine...

 

I guess I could just mount it on the back of the subwoofer box with my other amp....

 

if you are wanting to mount it under the passenger seat, it's do-able, but i would not recommend it. you have to raise the seat up about an inch or so, so that the cables and seat do not hit the amp, when you slide the seat forward and back. also, it's nearly impossible to adjust settings; you pretty much have to remove the seat.

take a look at Yanki's picture above. thats where you should mount the amp. if you don't want to mount it there, you can also mount it in the foam cubby off to the right of it. a little trimming, and it should fit nice and snug. put one amp in the spair tire, and another in the cubby, to keep it super clean.

 

i put my amp in the spare as well.. i also have an amp to the right of the spare.. im using computer fans to circulate the air.
only thing i did different, is i mounted my amp a little deeper into the spare.. so the floor will sit at normal height

 

mine is at normal height aswell.

 

If your amps are low profile you can do it like I did:
