I want to build an amp rack for my 2009 screw FX4 to hold my two amps but am unsure of the best way to do it. I don't have that much experience with this kind of stuff but my real question I guess is where should I mount it? I have seen threads saying behind the back seat is the best location and if this is the case, what do I need to watch out for? Will I need to cut that fiberglass cover at all that goes over the rear wall behind the seats? If anyone knows of any sort of informative guide on how to do this I would really appreciate it if you gave me a link! Also, I plan on putting 6.5 inch component speakers to replace the front and 5x7 coaxials to replace the rear, is it advised to go with the 6.5 inch up front and if so, how do I make a bezel for them?

 

Is it 2, or 4 doors? If your amps are both small enough i would place one under the driver and passenger seat if possible. I only have one, and was not small enough so i had to place it behind the center console and remove my cup holders because taking apart the pack seat looked like a pain.

 

Like most guys I mounted my amps on a piece of MDF behind the seats... works perfect.

Two amps mounted on 1/2 MDF, painted blue. Board was mounted to back wall over sound deadening. Then a layer of MLV was put on with the board space cut out, finally the outer foam cover with the same board cut out. There is a horizontal rib that runs along the back wall. I used two screws mounted into this rib. Make sure you don't use too long of screws, otherwise they will be poking out the rear wall.

The thickest amp is 2.5" and I would have issues with anything thicker.

...except I used 1/4 plywood to save space instead of MDF

 

Behind the seat for me also.
