Hey all, I dont know much amount amplifiers, but anyway, i have a Carvin 15" 100W combo amp and it sounds like wind is blowiing through when you turn it on. And when i plug in and play it sounds real quiet, and muddy. I dont know if i blew the cone or if ther is something wrong with the amp itself. Any suggestions? I dont want to have to pay to send it to San Diego to have Carvin look at it. Thanks.
