diff in db based on tuned box

I understand. Expresso it is. Thank you man. Im running one of those junk duralast as the main unit because its hard to find a highend battery to fit the small neon sized spot. I've got 2 small drycells (like each is the size of an aftermarket cd player) I use to run them in my race car. Would they be good or would u go to a full size. The car is kinda performance oriented right now but at this point, if it takes a fullsize battery, then thats what its getting. To me it can be the only culprit left. But I havent been doing this for years like some of you guys.

 

Oh and that setup is gorgeous

 

I've got a red top and have a few friends that had em go bad in less than 2 years on daily drivers
