Ok, here is my setup. I have a 1 year old OEM Alt, a 1.5 year old OEM Battery, big3 done in #4, #4 gauge power wire splitting into 2 8's, i bought some good stinger gold distribution blocks, gold GM terminal adapters, gold monster terminals, 2 500uF capacitors, a 800W sony amp powering 2 10'' Rockford 150/300W subs in a nice Rockford box (dont know what type, the sub fronts are sealed in plexi and the box part is ported), a 600W 4 channel ExilE amp powering 4 pioneer speaker, and a good panasonic Deck. I am planning on getting a yellow top battery.

So time for my questions:
What is the size of the yellow top am i after?
Should i delete the caps from my setup? I read that certain setups have no use for them.
I would like to get the most out my little subs as i can without replacing them.

Thanks in advance

Oh, 1 more thing i do not experience dimming but if i have my heat/ac on full blast i can feel/hear it die a bit, although its much better than before the big 3
