I got a 2k2 alti. Im outside cleanin it today an after 3hours the front console short out an came back on so i went to see what the prob was. I put it on radio it goin ok for a few min then it happen again. I go to put the amp off bass boost it go ok then it cut off again. I have my amp n sub hooked up to the factory console. I was wondering if the batt is dyin an if/when i replace it should i get 2 batts...one for the amp 1 for the rest of the car. Also i hear a buzzing noise comin from the batt when the key is turned to let the power on.
