i just bought a kicker L5 12" Dual 4-Ohm subwoofer, and in my car now i have a 12" bazooka tube powered by a 600 watt amp. I have a 99 VW Jetta with 8 speakers and also have a BOSS 6.2 LCD Touchsreen Radio. i dont think that amp is going to power that new kicker so any help would greatly be appreciated.
