Amp not working?
So I have an Alpine MRP-M500 and I got it all hooked up and everything and no sound comes out of the sub!
Upon powering up the car, the light on the amp comes on, on then quickly goes off.
I pulled out a multimeter and checked all the connections, they seem to be ok. But then I check the amp and between the ground and power in terminals, there is 500,000 Ohm (0.5M ohm) resistance which seems kind of minor but could this be the source of my problem?
I don't know why but sometimes there is no connection between the power and ground terminal, and then when I start connecting things (maybe the RCA inputs), I get the issue (I think).
Could the amp have some kind of intermittent connection?
The car still runs fine and the stereo still works and all, just the amp doesn't power up (not enough power from the battery perhaps as it is a regular car battery)?
