Conclusion: This amp has been great in my '99 Ford Taurus. I'm running two 10" Kickers with it and they hit clean and deep. I've never had the amp overheat and love how small it is. I would recommend this amp to everyone.
Conclusion: I chose this amp because of room restraints and wanting to try the higher efficiency line to lower my amp load on the vehicle. After having stereos with up to 360 amp loads I didn't feel like making major electrical system upgrades this go 'round. I am pleased with the sound quality and how cool this amp runs. I have always been impressed with Kickers quality and this is another quality piece that I would recomend to anyone.
Conclusion: Just installed this amp, powering a 350W RMS Kappa 10 sub in a sealed box. Nice amp, makes the sub really sing, good consistent power, comes with the remote bass boost which is nice. The small footprint was key for me, had a very small spot under a rear seat & it fit. Birthsheet was a little underwhelming at 506 W but initial performance has been very good.
Conclusion: Admittedly, I'm not a high end audiophile, but I know what I like. When I decided the car stereo needed a bit of an upgrade, I turned to the Kicker line. I was after a nice tight bass, with a good 'kick' and not a lot of that slobbery droning undertone. So I turned to the 500.1 and teamed it with a single Kicker 10" sub. I couldn't be happier! (well I guess I could, but it's not the systems fault).
