    Kicker is a superior brand. The quality of this amp exceeds all expectations. Its low passover and Gain and Bass Boost features are extremely fine tuned and precise.

    Good to pair with a 10 inch especially the comp r but underpowered for a nicer vehicle with a 12 tried both with amp and I’m impressed it handled my 15 well for a 400 if you don’t want to up to the 600 or 800

    Still going strong. Running 1 sealed 12 in subwoofer at 2 ohms. No headlight dimming no need for serious upgrades to big three. Running this off of 4 guage CCA no issues after 2 years.

    Works like a charm, If you are using certain speakers and sizes it's a great amp. I had it on a pair of MTX 12" subs, it sounded good until I let them get a taste of the Kicker 800.

    I really like this amp. Best Buy had the lowest price online and amp was in stock. Win - Win! This amp is powering a sub inside a Genesis with a Lexicon sound system. Sounds amazing! This amp can hit hard!
