Question about Alpine MRP-M450 Car Audio Amplifier
It's not a wide setup, amp is going to 2 woofers like it did in my previous vehicle.
HU powers up w/car, amps power light briefly turns on and then back off.
Not sure whats up...
Tested power - 12v
The light turns on which kind of tells me its getting signal from the HU, ie remote wire.
Sounds like a protection problem. A relay may be stuck, or there really may be an internal problem you cannot see. Take it to a shop to have it bench tested independent of your vehicle.
