I have 2 problems with my aftermarket amp I have added.

1. Sometimes when i turn on the car it sounds like the speakers are only getting a few volts of power to them. I have checked the connections and they are good. It sounds muffled and very low volume, turn the volume way up, and something happens and the speakers sound normal, or if you cycle the ignition it will work fine. Is this caused because my Alpine amp does not support Differential speaker inports, so it is getting confused as to the actual sound level requested from the HU? Would a Differential LOC help?

2. After running my amp wire down the passenger side, it seems the car is low on power, or wants to delay shifts sometimes. I tried searching but the search function does not work very well. IIRC someone else has this problem and the routed the power cable to the amp away from the ECM loom? My cable is running through the same grommet, and right beside this loom.

Thanks,
Pete

 

bump.... Doesn't anyone run somthing other than JL amps? Someone has to have an alpine out there...

 

figured it out. One of the connections going to the speakers was touching the case for the amp chassis grounding that connection and causing the amp to power down. As for th ECU I think that was because the battery had been disconnected.
