ok ive ordered a 1200 Watt sound system for my car and the battery that i have dies if i leave the accesory switch on it kills the battery had to jump it twice so im wondering if i should get a more powerful battery, a battery just fo the system also i would liek to know ifi could get a more powerful alternator for the wattage im looking at.

 

A more powerful b attery will probably only be good for more cranking power. How long do you leave the acc switch on for?

 

maybe ab hour two hours at the most when im cleaning the car
