will a second battery do me any good?

[snowfighter]

I have a 120 amp alt and a yellow top optima with 0 gauge to the amp "which is a hifonics brz 1700" and I'm doing the big 3 this weekend. Does anyone think that I will benefit from a second battery and why or why not please!!!

Thanks

Yes, it will keep your voltage up. get a xs d975

Yes, more capacity when vehicle isn't running. More reserve capacity when winter outside.

It will help keep you at or above resting voltage under heavy loads but that is about it if your alt cant keep up.

If you need a battery, let me know.

Well I can get another yellow top for 100 so I think I'll just go ahead and get it. Thanks folks I really appreciate the advise. If nothing else it will be an on demand jump start!!!
