Excellent amp.
I have a subwoofer that is connected to this amp. It really provides a kick of bass! My car is constantly booming. I use this with a Boss deck. I had a Boss deck that lost Bluetooth connectivity. It was under warranty and they provided a new deck. I installed it myself without problems.

bossの2000Wのスピーカーと組み合わせてとてもいい物が安く仕上がり大満足です。 印加時にbossのロゴが青く光るのには驚かされました。(OFFスイッチが欲しかった>< 本体が直射日光に当たるせいか、1年で表面の黒色が少し茶色っぽくなっています。
