i got a brushing/ raspy sound in the background of my music. only noticeable at low to mid volume. its not a buzzing. its only when music is running if i pause it there is only silence(at all volumes) like it should. so im guessing its not signal interference. any ideas? maybe the cold?

 

very cold temperatures can have an effect on amplifiers. if you notice the problem goes away after the amps are warm, or on warmer days, then it may just be a solder joint issue in the amp - something that is repairable.

 

ive only driven twice since then but the brushing sound seems to be gone. ??? im confused but not complaining. hopefully it was just cold. thank you for the help
