I need help guys; I have the stock radio head unit and Boom speaker’s front and back. When playing music thru my I Phone 5s (connected via the radio front plug in) the sound quality just isn’t that great, and I have to almost max the radio volume to hear music on the Hwy. I’ve tried the various “music EQ” settings on the I Phone (loudness, bass booster, acoustic, etc.) but I can’t find one that gives me great sound. In Contrast my old Blackberry sounded fantastic when plugged into the same bike with the same tunes. Any ideas???
