XS Power D2400
This is an awesome battery. Already had one under the hood so when I upped my power and needed an extra battery, the choice was obvious. These things are great and keep my voltage where it belongs. Sound Solutions Audio has very good prices and excellent customer service. Aaron and Josh have really helped me with my new system. The best way to contact them is via email, but they will definitely get back to you and get you the answers you need.
