Review on Soundstream VR 620HB Touchscreen Receiver Bluetooth by Paul Bijeaux

I have a Nissan Titan with Rockford Fosgate system, no car wire on amp, although many sellers like ebay say you need to get an RCA harness and it works, I had to hook up the amp to the ACC. Every time I switch menus, e.g. B. from CD to radio or telephone, or turn on the truck, I hear a loud bang from the speakers. The touchscreen doesn't work half the time either. ALSO there are other almost identical radios under a different name, such as the POWER ACOUSTIK PD-620HD.
