Distortion on One Channel

[NaOH]

I have an amp that adequately (or supposedly) feeds 4 speakers. For some reason, one of the channels gives distortion only for the low notes. I switched the channel over to another speaker that worked fine and it sounded bad. The highs sound very good, it's just this weird crackling bass......

Any ideas?!

"Any ideas?!"

either the amp is blown or one of your speakers is blown
