My voltage meter has been getting low readings lately and it is making my JL 1000.1 amp cut out because of the volts being so low. I was wondering if my battery was bad or could it be my alt. or do I need to do the magic 3. I also have a PPI amp powering my comp. speakers but they never cut out due to the low volt why is this?

 

id try the magic 3. how low is it going? must be going pretty low for the jl cut out.

 

how many volts is it reading with the engine running? it could be your alternator headin south

 

most likely the alternator... but first thing i would check is the amp ground.

 

I agree. When the alt goes you normally have some other issues as well. I would definately check out your amp ground, might be corroding.

 

The volts drop below 10.5 when the car is running and the system is on. I have to turn the bass down or turn down the volume to make the amp come back on. I guess I'll do the magic 3 and check the ground.
