Hello All, first time poster, woo hoo!
I just bought a used AV123 MFW-15 subwoofer and noted it appears to have a bad amp. When turned on it produces a pretty loud hum, louder than a ground loop hum I think. I was going to search for this on here to see if others had this issue and knew how to fix it, but I need three posts to get to that, so HELLO! If anyone has a thread they can point me to, I would appreciate it. I actually have an unused powerful amp, but just need a little guidance to connect it to the sub.
Thanks - friendswithdave
