Hey everyone. Was thinking of picking up a Crescendo Audio BC2000D amp to run 1 15" sub. My question is what kind and how many batteries do you think i would need? I have a 200 amp alt. and have done the big 3. The car this is going into is not a daily driver. Mostly just to car shows. Any help would be great. Thanks

Put it all in and see where your voltage is and go from there.

Which batteries do I start with? Right now I have a red top optima. I know I need at least 2 batteries. I've read that you should run two of the same to prevent draining one of them.

You have a decent size alternator. Put it all in, set it how you want it, play it and check your voltage. Only then will you know what you need.

Ok. I'll do it in the next couple weeks. Have to order the amp first. Just trying to get a jump on things. Thanks

At most I'd think about adding a single agm battery in the rear.

That would be a simple 12v battery? Just asking because the alt is pushing 14.5 volts. As you can tell I dont k ow much about batteries. Sorry for all the questions.
