So about a year ago I was given a pair of RM9s (6x9 inch) and a pair of CX3s (3.5 inch) (both made by Boston Acoustics) in return for helping someone move. I was going to use them, but never got around to installing them in my car. Now I am going to school and am selling them. Problem is, I have no idea what the value is. MSRP for the RM9s is 100 each and for the CX3s 150 each. However, I really do not know when these speakers were first manufactured and what the current value is. They are in very good shape. I'm not sure if they have ever been used. Any help on pricing would be appreciated, as I do not want to get ripped off or overprice these when selling them.
