Bass Blockers
Would bass blockers keep my speakers from distorting at mid-high volumes with bass heavy music?
4 6.5″ speakers(2-35w RMS) powered by the head unit (20w RMS per channel x4)
your stereo is putting too many watts into those speakers which cant handle it.. to solve this either.. get new speakers which can hold a higher amount of RMS watts which equal to about what your stereo gives out… or keep your volume at a lower level
