Thinking about selling my rockford 600.1bd. It is in protect mode and Im not sure what to do about it. Im somewhat new to amps, subs etc.. so im not real technical. Local audio shop had it wired correctly but couldnt say anything about what was wrong without sending it off. Ive kinda been wanting to upgrade anyways. But if someone will give me 120 shipped obo, ill let go of it.. Im new to the forum but have 100% positive ebay feedback and a few references on fordtruckworld.com and highlifter.com. If anyone might be interested Ill get some pics.
