What I am having trouble with is my size restrictions. I'm asking for help finding quality components in that size. I need a 12" sub that will fit in a 8.cf sealed box with a max mounting depth of 7". 7" is pushing it depending on the magnet size. I'd like it to be capable of 500w rms. Then I need two amps one 1000/1 for the subs and then another 4 channel to run my front components and rear coaxials. I'd like the fronts to get 150w rms and the rears about the same maybe a little less. Both amps need to fit on the rear cargo tray.
