OK, if I upgrade the stereo as in a previous post and add another battery to power the amp/amps what are my options. Optima, regular marine grade lead/acid or what. Then, who makes boxes or hold downs for them. Went on CP's site and there aren't many options.
Thanks, Dave

We offer what I believe to me the nicest 31 series or the largest Optima sized battery box. Take a look and see what you think. http://www.hardin-marine.com/detail~ID~1816.aspx

Diamond Performance has some good prices on battery boxes.

I know this will open a can of worms but what batteries do you guys like. I've always used the regular marine lead/acid type. Buy them cheap and replace every two years.

What about Kinetik Batteries?

Also try and find the exide distributor in your area, Ive been buying the blem blue tops for 50.00
