Hey all. I have 2 JL stealthbox i am looking to put into my M3. I have a traffic pro headunit. I guess my question is what sort of amp should i purchase. Also do i need to get a capacitor, i have an underdrive pulley.. however i probably will take that out and replace it with the OE pulley in favor of a lightweight flywheel. I believe the stealthbox's are W3s and they are the 8inch.
HELP !
