I am adding this as a second battery in the trunk, and undecided on the BLUE or YELLOW top optima battery. Which color optima would be best suited for car audio system and a brief description why would be appreciated. Already have upgraded electrical. Any suggestions? Thanks in advance

The yellow optima is specifically for car audio. The cranking amps is 750 but all are underated. IT should be around 850 to 900 cca. Mine i have had it tested and its cold cranking amps is 1126 So i have left my system on for almost 9 hours without the truck running and i went to start it and did not hesitate one bit.

I know a guy that runs red tops cus he fried a few yellow tops. The red tops seem to be doing him good though.

blue and yellow optima batteries are the same except for the post. taken from optima's website;

The difference between BlueTop and YellowTop deep cycle batteries is that BlueTop batteries have both automotive (SAE) posts and threaded posts, while YellowTops (other than D31T) only have SAE posts.
