i just bought 2 BLs and the SAZ 2000 and was wondering wat would be the ideal battery i should upgrade to. i heard yellow top was great but some have been saying they have been getting worse and just increasing in price. not sure about kinetic. and im pretty sure meade uses the AGM so im sure they r good.

A Redtop Up Front And A Powermaster D2700 Or D3100 Should Do The Trick, You Would Have Plenty Of Reserve With That Starting/Aux Combo.

Once i get my setup i will be running two XS Power d2400. I will be running two BL 18s with two Sundown SAZ-1500d.

The above choices are good but with just the 2000D i would suggest getting a batcap 2000. I was going to get a XS d3100 but i was swayed to get batcap from a local car audio shop and i am very impressed with it. I am running a Saz-3000D off of one with the stock alt and its holding up strong. Although it drops to ~12 with steady bass it never goes below. I think 1 will be great with your set up.

In the future i plan to get 1 or 2 more though and a HO alt but thats just cause im running 3k watts.

maan im in the same boat as you, i still cant decide what battery or batteries i wanna get. i have dealt with the batcap 800 in the past on a smaller system and was impressed with it. so i want to run 2- batcap 2000's or just keep my stock battery and get a batcap 4000, or get two deka 9a31's with the stock battery. so many decisions i dont know what to do

Kinetiks are awesome.

I like my 4 hc2400s
