This weekend my battery drained. I had to jump off my Goldwing. My system the MC-HON- AMK with BT 6100A was working perfect prior to the drain now my speakers in the front sound crapy. There is no sound from the rear speakers but the BT6100 sub is working well. There was no problem with the fuse and the amp is on but my question is: Is there a way to check the amp to make sure all 4 channels are working? Is there a reset button? Is this a common occurrence after battery drain and jumping the Bike? The unit has been on the bike a year now. Any help will be greatly appreciated.
