i got an 03 tl-s im going to upgrade the sound system in a few months and i want to put a bigger battery...

what have you guys stuffed in without any problems?

 

Optima Yellow fits With No Issues and Will hold up to 1K RMS Easily.
(Currently have it Installed)

Then Kinetik about the Same Price but starts higher $$$ = More Power.
(Had the HC1400 Installed way Overkill for my System, Sold It)

Then XS Power but thats for Serious really High RMS...
(Never had 1, Heard alot of Good Stuff about them)

 

I was also looking for a battery... I have 2 Rockford Fosgate amps. T1500-1bdCP and T600-4. Any Ideas???

 

I also have a T-1500bdCP pushing 2 Rockford P3 12's and I have an Optima Red top battery. When I turn it up a good bit and it really starts to hit, the lights do dim. I think I'm just going to go with a capacitor though.
