battery upgrade?

[kwilli32 0]

I have a 2008 trailblazer with stock electrical. I have the t400-4 and a t1000-1bd. Will I be alright with the big 3 and a new battery, like an optima redtop (yellow top wont go in my car) or do you guys know of any better batteries for about the same price (under $200)? Also, where can i get 0 gauge battery cables for the big 3?

Try it stock and then see what you get. Personally, I'd do the alt before the battery. If you're spending $200, why not spend another $150 and just do it right? . . .
