Does the job!
This amp is part of a complete audio system I put in my 2001 Jeep Cherokee XJ. I'm using it to bump up the power to four Polk Audio db651s speakers mounted in the stock locations. I set the cutoff at 60 and am running a RF Punch P300-10 for the bass. It has its own built-in amp. The Polk Audio speakers sound great so the amp must be doing something right. It's mounted behind the Kenwood Excelon KDC-X300 in the dash. Out of sight, out of mind.
Pros: Wiring was easy. It matched up nicely to the Kenwood harness and the vehicle adapter harnesses. Just a little head scratching, but it all worked out.
Cons: Got nothing. It works for me.
