na this ones gonna be my final audio build for the car, the jackhammer with those subs should put out 145 db or above in the box im having built, and thats about all im ever gonna want

my audio shop in town said I could get by running a second battery as long as it was a depp cycle or a dry cell and im inclined to believe them considering the owner of the shop owns a grand prix as his personal audio car with alot of experience and awards under his belt, but I'de rather check with people on here first
