Question for those with aftermarket amps.

Depending on what size amp you choose, you should have no problem, and there is plenty of airflow under there. but if you ever put subs in your car it will be a PITA to get your RCA's and power wires back in the trunk and under the seat.

FYI if your not into super systems a great budget setup is a 5 1/4 component set with 35.X 2 rms amp. only amping out the front and let the HU amp out the rear.
