i have two kicker cvr12 woofers 400 watts each,beign power by a us amp hc50 375 watts at 1 ohm, i can hardly feel the bass.it feels as if the woofers werent getting enough power.
autotek ss 750.1. you can pick them up on ebay for 175 shipped. great power at a great price. pas mag did a review on the 500.1 and it did 150+ over it's rated power.
