great price, easy to hook up, bluetooth hooked up with no effort. After going through 2 receivers (which has fm/am, cd, etc) over the last 3 years on an outside patio area, i only use this now. My system is simple, amp plugs into wall outlet, one channel per speaker, thats it. It is hooked up to 5 outdoor rock speakers, so i still have one channel left. 2 of the speakers are https://www.amazon.com/gp/product/B00CZHUNKS/ref=ppx_yo_dt_b_asin_title_o09__o00_s00?ie=UTF8&psc=1 the other 3 speakers are older but very similar. at full blast there is no rattle or distortion, have to turn it down just a bit for conversation (on a 20' x 50' area with speakers surrounding it).

I needed an amp with tone control for my battery operated digital piano kart. It would be better with one set of rca inputs but I made do with splitters.

Easy to use, lot of different functions to chose from, fit perfect on my Golf Cart, and the sound is excellent!
