I just put in the J&M Rokker speakers and the 250 watt amp and I am not that impressed. So far the J&M system doesn't sound much better that my Hogtunes system did and I did not get any volume increase at all over the Hogtunes 140 watt amp and 5x7 speakers. The adjustment instruction video is not much help when it comes to a 2 speaker system. I don't want to open up the amp panels to locate the adjustment pods and so far any videos from J&M are useless. Anyone have any suggestions on how to adjust the J&M 250 watt amp for the 2 speaker system?
