Whats the model number on the RF sub?Rockford upgrade complete. The only modifications were drilling new holes for the speaker and grill, and a thin weather strip around the ring.
Nice tight punchy bass. Same results I had with this speaker in my Focus ST , and Shaker pro in my 16 mustang.

Real world trials beats technical specs every time.

guess I'll bring out the jackhammer then! I kinda guessed I would have to get a little sweaty - however I don't want to break the original sub nor the box and maybe someone had a trick so it was easy to achieve this
