Waiting for the J&M lower faring speakers, already have the 7.25's in the faring (like them alot), will be installing J&M's in the rear. Hving a hard time jsutifying the $00+ for the J&M amp though. Was thinking about going with the Hogtune amp and lower speakers for $300. Has anyone done this and is there any compatibility problems between the two manufacturers? Will I have any issue plugging in my JM speakers?
