Looking for an older Rockford Fosgate HE2 10 inch sub and the model # is rfp2210. It is a dual 4 ohm sub and handles 600 watts max and I believe 400 watts rms. It will say say RF in red and punch HE2 in white on the dustcap that is 3 dimensional. I put a pic up of what it looks like. Looking to spend around $30-$50 for one in fair, good or excellent/mint condition and both voice coils must work.
