Alright while driving today my front left speaker started cracking really bad reallly reallly bad. You guys hopefully know what that sounds like.

So i fold the seat d own to expose the amp powering fronts.......cracking goes away. check all connections all are fine. Put seat back up, amp now vertical,,,,cracking starts again.......

Is my amp possessed? Lol does anyone have any suggestions? I know for temp fix i just drive with the seats down but for longterm what do i do?
