Review on Blaupunkt AMP1804BT: Advanced 4-Channel Class D Amplifier with Bluetooth for Crystal Clear Car Audio Experience by Bryce Wohlman

I connected this amp to two full range speakers and two dual voice coil subwoofers. Everything is set to 4 ohms. I am connected in 3-channel mode. The instructions explain 4 channels and channel connections and specifically talk about 2 and 4 channels but not 3. Maybe it's just implied since they mention it. , but the instructions have a clear illustration. Very happy with it. This little 1600 watt amp should be running at 150 RMS. I have no way of testing this, so I'll take her word for it. I know this makes my speakers loud at max volume with low distortion. The built-in crossover works perfectly with a few exceptions. The HPF/Full/LPF switches and other controls that are present are not labeled for front and rear or left and right. Due to the layout of my speakers, it was difficult to know which ones I was controlling. But I found out, so I'm happy.
