I just ordered an 06 Supercab Fx4, and plan on putting dual subs under the back seat, I was just wondering where everyone puts there amp? From the look of most boxes available there will be on room left under the rear seats for them.

Thanks

 

With two subs under the seat you probably arent goint to have room for the amp there. most dual boxes take up the whole space under the back seat (unless you are going with dual 8 inch subs, which in that case you can get a box that will usually fit under the larger portion of the seat).

Many people put them on the back wall of the cab. Great place in my opinion, out of site, and dont take up any room. Under one of the front seats is also a nice place. If you take out the jack to put on your spare tire there is a little bit of space under there.
