OH THANK GOD, somebody finally SUPPORTS my second battery theory! Iv'e been running dual batteries for over 2 years now with NO ILL EFFECTS. The rear battery was recently upgraded to a HC 2400 KINETIK, and the system playtime with the key OFF has increased 3 fold! Upgrading from PS2 to X BOX 360 made my rear 800 amp battery go DEAD in about 1 1/2 hours. The new replacement hasn't crapped so far after 5 hours of play. This also powers my three amps and 20'' flat tv, plus an additional amp and speakers for the tv. TWO is the WAY TO GO! BSBOB
