Question about Alpine MRP-M650 Car Audio Amplifier
The Amp has power goin to it and there is 14v comin out of the ground which makes me believe that it has the sufficent amount of power needed but teh LED light does not turn on and nothing comes out from the sub at all. The fuses all look and tested fine which then brings me to asking part. Thanks for any help.
The built in power supply is probably bad. This supplyds the voltage from the 12volts and inverts it up to 20 to 30 mvolts DC. You will need to get a manual to service this unless you know the inverter circuit really well. good Luck
