I have a seemingly good hookup from a guy I work with to get a set of two 12" Memphis subs that look to be in good condition, and not blown up. He wants $50 for a set of two subs, no amps or box, or anything, just the subs. Should I get em? He's got two sets of two for $50 each. I'm still at work, but if anyone can tell me if these are good quality and good sounding subs, I'd appreciate it. Thanks in advance.
