[QUOTE="Alc1489, post: 8649555, member: 675290"] So I have a 2012 Buick Verano with Bose system. Added a JBL GTX500 with a Pioneer champion 12 dvc 4ohm 400rms in a sealed box. Im thinking about buying another sub. I know the amp would be underpowering but i also have a premade dual sub box thats 1.5 cube each sealed that i want to put an aero port on each side.
