I know Evan and I know (for the most part) about his car.

I don't think he needs a second battery with only 2 subs and one amp. I would say larger wires, a cap isn't necessary but helpful, and a battery upgrade. I stepped up to the Optima yellow top (just don't get the D51 for the Honda) and it's been great!

I had the smaller Optima that is fit for the Honda's and it had this funny little breather hole in it. My battery is mounted in the rear hatch area and one day the battery shorted and was spewing acid all over!!!!!! Real nice for a DRY cell battery.
