How are you guys mounting your amps on the rear cab wall under the window? This really isn't the route I want to go but I can only fit 1 under the pass seat and I can't think of anywhere else to mount the other one. They are both about 13"X10". I am using a thunderform too. Thanks.

 

i mounted a board to the back wall, then mounted the amps to it.
