battery question

[tosh 1]

Need to replace my starting battery on a 1999 chevy s10 blazer.Whats a good replacement to keep up with around 1600 watts. It needs to be able to match up with a second battery in back if i decide to add one. If there is not a big deal i was just going to put in a die hard gold and be done,but want any imfo/help before spending money.
