[QUOTE="Divvy, post: 8736583, member: 682353"] Hello car audio lovers! Today I installed a new amplifier in my car, but the the power light wasn't illuminating. I tried measuring the voltage to it, and found out it was only 3-4 volts, but when I removed the REM wire it spiked up to 12 volts. The REM wire also measured 11-12 volts when I disconnected it from the amplifier. Im far from an expert in car audio, but this seems a bit strange? i also tested by taking a wire from the 12v terminal to the rem input, and the voltage still stooped. The fuses on the amp is intact. Its a DLS P44, installed in an Audi A4 B7 2006. Thanks for answers/suggestions! :) [ATTACH]27084[/ATTACH][ATTACH]27085[/ATTACH][ATTACH]27086[/ATTACH][ATTACH]27087[/ATTACH] [/QUOTE]
