Poss Bad Amp ???
Replaced the battery on my 2001 Gold Wing and now my sound system sounds like crap have 4 channel amp with ba6100 I hear a crackling, almost cutting out in the speakers, sounded great before the battery change.. Filter switch and gain adjust make no difference.. Checked all speaker connections ok, listened to system through headset and sound is good, Checked power and ground.. Does this sound like a bad amp problem ???
