Alright I have had an interfire IF 4900B amplifier and two audiobahn AW120XS subs in my truck for about 3 years now. I dont know much about stereo stuff, all of it was given to me by my brother. I have gotten a new ride recently and dont have anything to do with it. Does anybody know about how much that stuff was/is worth? It has never been abused or turned up way high or anything, only regular use. Thanks in advance
