I highly reccomend a kinetik battery. Optimas not soo good.  If you are going to add a second battery get a good quality battery, and USE AN ISOLATOR.  If you do not use an isolator, you will cause your factory alternator to fail prematurely.  I ran a 2000watt system with a facttory alternator and dual battery setup for 3 years with no power issues at all.</p></blockquote><p></p>
