Report "I have a memphis belle 1300 5 channel amp and recently the front right channel has started cracking and popping. i hear it at the same volume when the volume is up or on mute. the speaker still plays but im afraid im going to hurt the speaker by running it this way. there is nothing wrong with the speaker or wiring cause i tested another amp and it runs fine. what could have happened to my amp and how much does something like that cost to fix"
