i have 2 rockford 12's, they are the 300 rms with the chrome dustcap, i will have to check on the model #. they are powered by a jbl 600.1. they are in a ported box, and the amp matches up with those subs perfectly as for power. the subs are perfect cosmetically and play perfectly. the amp has a minor cosmetic scratch, but plays perfect. not sure what i want to start at, offer?or will consider trades.
