Hey guys I was wondering if y'all could help with an issue my brother in law is having. I sold him 2 Sundown E 10's with a Solid Audio F11D about 2 months ago. The subs were basically NIB and the amp was purchased in 2012 NIB and I ran it until this year and never had an issue.
So he is telling me that in the mornings only, the subs are making noise (sounds like wind?) with no music playing. Basically have a constant tone and bump every once in a while. After work, he never has the issue. He had an old pioneer deck that was giving him whine noise but he got a brand new pioneer and it doesn't whine now. Vehicle is a 2003 Chevy Silverado Ext Cab. He took the cats off which rattle everything but this isn't causing the issue. Any ideas?
