Question about Car Amplifiers
I bought a Kenwood KAC-8403 amp a couple of months ago, and hooked it up to my car / sub. There were existing power / ground lines in the car from the previous owner. Everything worked fine until a couple of days ago when I hit a bump, and my sub and sound went out. Now the amp wont power on, andthe only time it shows any power is when I disconnect the power cord. Any ideas?
With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage drops below ~11 volts, you need to check the wiring feeding whichever line is too low.
