i went fairly cheap on this setup im pretty happy with the results. the headunit is a jvc kd-r640. aux port flash driver pandora radio ready. multi color display. the subs are mtx terminator 12s in sealed box. the amp that cam with them was a mono block 250 mtx but just wasnt quite running the subs good enough so i put in a kicker mono block 350 and now i got all the bass i need in my car lol
