Question

why is my amp shuting off when my car is on acc. its like if my car is dead but it still turns on, only wheni turn the bass up. could it be my battery the is draind

Answer 1

If your battery was drained,you would not be able to start the car.You might have the sub wired at to low of an ohm load for the amp and when you turn up the bass the amp over exerts itselfs and goes into protection...but a battery that is low will also cause the amp to do the same however once its at that point you wouldnt be abkle to start the car...does it work fine with the car running?

Addition:Hmm ,if it works fine when running then more than likely its probably your battery.Most likely your amp draws alot of amperage with those bass notes and your battery may have a dead cell .I had a rockford Fosgate punch 150 limited edition that pumped out about 996 watts...it had 3-40 amp fuses and I had a similar problem but it would kill my battery almost instantly....But it worked fine so long as I kept the Truck running....I replaced the battery and never had a problem since.Have the battery load tested at walmart or any autoparts store(autozone.hi-lo,orielly, etc...) they will do it for free....Then if its bad,replace the battery with a deep cycle battery like a optima red top....if you cant afford the optima,then just get a SLIGHTLY larger battery....A larger battery will allow you to listen to your radio longer with the car off.

Answer 2

When your car's on acc your system is drawing power straight off the battery and the power isn't being replenished by the alternator and your amp is cutting off so it doesn't get damaged.
