The highs are going through my amp. I have the Kenwood 9103D amplifier. Have not tweaked any of the settings besides bass boost. When I listen to rock, the bass guitar goes through and sounds horrible. I even have my headunit set on to subwoofer mode but it only has 2 RCA inputs in the back. You can turn the subwoofers off from the head unit. I usually listen to rap but how do I fix this for rock
