okay so I had a post on here earlier about my car not starting, and decided that it was time to get a battery. i have been frantically searching for a yellow top battery, however, i cant find one that is the size 35/78...I went to the optima website and according to them, they have that size. does anyone know of an alternate battery or where i can find another deep cycle battery?? i think my 500/1 JL Audio mono amp and JL Audio W7 are ******* away most of my power...so i would need a battery that could handle that kind of power. Thanks Guys
