Kenwood X Series X302-4 Class D Mono 4 Channel Power Amplifier, 600W Max

Kenwood Excelon line is good quality and a reliable brand. This amp is clean sounding and well built. Sure this ain't very powerful, but at 50 watts rms @ 4ohms it's good enough for the average listener looking for a step up for their factory system. There is no audible noise issues. I have it hooked up using the factory high level input on the amp. To the factory radio. And it still sounds good. Sound is louder. It sounds more powerful adding depth to the music. It has high resolution output if you use a quality high resolution format. It is also best to upgrade the speakers for best sound experience. This amp is an older version. They have a newer version but it's twice as much. I would consider this amp mid grade. Not audiophille but not cheap quality. Good for avid and music enthusiastics without spending an arm and a leg.

I love Kenwood, and their Excelon line is awesome. No whine. Just good, clean power.

Works and sounds great.

yea, they are a version old now, but sound great and at less than half price of the current version, highly recommended.

First off I wanna say I've always been a BIG Kenwood fan (cassette/stereo/cd) since the late 80s. But my recent build /mid life hankering, I kept blowing tweeters til I run across a familiar name brand been pissing neighborhood off since. I proudly recommend this proven brand..

Didn't work on speaker level input

So far so good. Got wired to fosgate 6.5 components and bridged rear to 1 kicker 10. Sounds great
