I have a 12 inch diamond sub. Yesterday it started acting up. I checked all the wires that are connected to the amp and sub. I havent checked behind the headunit yet. But it cuts out and back on alot. Do you think its blown?
I had the exact same problem, and it turns out it was just a blown fuse due to it being either just faulty or running the subs too hard for too long, so just check your fuses.
