This is what I use, ive not actually seen anyone else but me use them.... But I have no complaints. Might want to give em a call at least and see what the pricing is for you.
I would have to agree with the Deka's. I run 3 G31 Intimidators as back up batts and my voltage stays very strong. But I also upgrading the batt and wiring under the hood and threw a 220A alt in.
Is there a difference between like daily driving batteries and .. sound system batteries?? Would a kinetik perform daily well? how many cca should i get to fulfill my cars needs?
