Currently I have 2 Pioneers in the front and 2 Kenwoods in the rear (both about 22w peak) with an Alpine CDE-102 head unit powering them. For the sub I have an 18" JBL (rated for 800watts rms at 8ohms, 99DbSPL @ 1w/1m) in a enclosure I built my self. Its dual ported, tuned to 24Hz, and designed to also double as my PA sub woofer for shows =). My sub amp is a American Pro VS1405, just until I can afford a more powerful amp. It is already shaking my mirrors and I can feel a minor amount of flex to my roof.
Thoughts on a new amp that can put out ~600watts rms at 8 ohms that isn't too expensive?
