Great little amp
Some of these other reviews are ridiculous. They’re expecting way too much for the size and cost of this amplifier. Done correctly. This amplifier will play nice and loud in most vehicles. it’s not going to win any awards for over-the-top sound quality but it doesn’t really really good job. The adjustments to block bass and set levels are easy to set and reasonably accurate. If you are looking for an amp to drive some middle to higher end speakers in a smaller vehicle, this amp is a great purchase. I am driving to 6 1/2 inch woofers and 1 inch tweeters on their own crossover network on channels, one and two. Channels three and four are bridged to run 2-8 inch JLAudio subwoofers. It hits hard and will play all day without distortion. Thanks Soundstream!

Small but powerful
Great sound for a small amp, good for mids and highs or even 6x9s

Exceeded expectations for the price.
Solid amp, Tends to get hot a bit easy. But for the price I paid I definitely expected it to be a lot worse than it is. When I first unboxed it the adjustments on it were kind of knocked in. I was extremely disappointed with that. Everything was still functional but I was upset with the condition it arrived in.
