Question about Alpine MRP-M650 Car Audio Amplifier
Ok i got an amp installed and would most of the time not have any sound. power is on(has the light). wat am i doing wrong?? also, when it does work my amp shuts off. and when i turn power on, light comes on and fades away immediately. are all these problems related?? pretty sure all cables are connected
Check voltages at the main power lead to/at the amp and also
at the sense wire which switches it on when the radio is on.
Might be the wiring is too thin and is switches off when current is drawn bigger than that needed to light up the light?
That or the switching power supply inside the amp is unstable/dead.
