Here is an all original, genuine Rockford Punch 301M all metal end cap, not aftermarket, 3D printed, machined, etc. It also includes the OEM mounting screw. The cap is in very nice clean condition. I do not know what other amp this "may" be compatible with, so buy at your own discretion as there are no returns, refunds, sold as-is. AI says they are compatible with 1996-2000 Punch .2 Series, i.e, 100a2, 225.2, 250a2, 360a2, 400a4, but again, I cannot confirm that. The measurements are as shown.
