What is the reasoning for the replacement? Is it due to the constant and excessive current drain when only the 12VDC+ and 12VDC- are connected up? I have that issue with my amp. It has drained and ruined several batteries before I found that it was the amp doing it. I took it back to have it replaced with only the same problem. JL Audio refused to repair it under warranty.
