ok here is the scenario:

im running 2 BLs off of 2 1000.1 kickers and am gettin some dimmage(only when i turn it up), everything is stock

question(s):

whats the difference between a red top and yellow top(which is better reccommended if at all)? or do i need to get an xtra battery and/or cap?

should i go ahead and attempt the "big 3 upgrade" to see if it helps any?

thx in advance, and sorry, im noob when it comes to this stuff

What kind of vehicle is it going in?

you should have done the big three to start with... i would indeed run a second cell.. but thats just me.

07 tahoe, i might decide to try to do the big 3 upgrade this weekend if i get time(school n work ftl )

so wat about the red top vs yellow top?

yellow top is dual purpose, starting and deep cycle duties, and would be the better of the 2

If my choice was limited to just a yellow top, or a red top, I would have to pick the yellow. They were designed solely for purposes like car audio, and racing where they don't run an alternator. It's meant to handle heavy discharges.

i donno about sole for car audio but the blue top also says for car audio... i called optima my self yesterday.. thay said they are all made the same but they all have diffrent power amounts.... so im now running 2 yellow 1 red and 1blue and one off brand
