I bought this amp for my Miata after receiving professional sound system advice. Grouped with a Sony head unit, Infinity speakers and a Kicker sub, this amp really drives some sweet clean sound. I don't play it super loud but rather look for quality sound - tough order in a top down Miata - and this equipment delivers. Recommended.

This a good amp for the price. The power and sound quality are good. The built-in cooling fans are okay, just make sure it can get some air flow, it does get a little hot, but I push it hard for long periods of time. The built in crossovers work really well. I have this matched up with a Clarion head unit and 4 Memphis Audio 5X7s and it rocks. The prices from Sonic Electronix cannot be beat.

The Kenwood amp is an awesome amp. Quiet, powerful, stays cool and easy to setup. I am running Polk speakers with this amp in conjunction with a zapco competition series amp. Excellent amp for the price.
