J&M 250 Amp question for JM John or anyone that has an answer
Hey JM John, I had a J&M 250 installed some time ago by a local stereo place and connected to the Boom speakers I was running at the time. I just now purchased a new set of JM Rokkers XX 7.5's and installed them.
Was I supposed to do anything like adjustments or tuning?
12 FLTRX BBP SERT SE A/C V&H Power Duals & V&H HO Slip-on's + a few more goodies, Andrew's 37H = 99 HP & 110 Torque (after a proper tune at Pensacola HD)
