what the differance between fosgate punch and power? better insides and or warrety?

I believe the punch is the cheaper of the 2. Ive heard both and think both sound alright. The high end punch speakers are very good.

their for my girlfriends car i don tlike the her fosgate sub their kinda sloppy on fast beats but it her car and she bought them. im hopeing this new amp will help clean up the sound cuz the old lanzar sucked but it was cheap at the time.

Yeah a new amp and maybe a good crossover if she doesnt have a good one in her HU would clean up the beats for you..

she has a alpine i donna what model all i know is that it cost $350 so it better be good we didnt pay for her cd player insureance did cuz her old one got stolen
