Review on Compact and Powerful: Soundstream ST4.10000D 4-Channel Car Amplifier - 90WX4 by Brandon Thompson

I just installed an amp on my bike replacing a 2 channel Kenwood. It is very important. I read reviews that there were some clicks when playing music out loud. As soon as I tuned it in, I turned on the music and listened to pops as well. However, I did not connect the ground to the speaker level inputs. Once connected, oh boy what's the difference. The music is crisp and has that mid-bass all the way to the top and bottom panels, with the music midway through. I will ride it for a while and give more ensite. But if you decide to buy this amp, you will not waste your money. Just remember to connect speaker input ground.
