[QUOTE="pino, post: 7757272, member: 642025"] The amplifier was installed perfectly in the back seat passenger of my SUV, i used 4 gauge wire for power and ground, 16 gauge wire for four JBL GTO638 6-1/2 (60 Watts) speakers (2 ohm each one), 12 gauge wire for one Rockford Fosgate R1L-2X12 (12" 300 Watt 2 ohm). I followed all the configuration steps as mandated by the Alpine manual. The problem is that the amplifier sounded perfect the first day, but the second day on my way to the office it stop sending signals to the speakers, the blue light of the amp still ON and everything is ok, the voltage, the signal output of the Head Unit, all cables and connections, everything is fine but no sound. My head Unit is a Kenwood KDC-152 it only have 4 channels speakers outputs + 1 RCA Rear/Subwoofer, so I connected all 4 channels to the amp's high inputs and the HU's RCA to the RCA input for subwoofer on the amp. Can you guys help me to determine what is happening please? [/QUOTE]
