what are you on? :/ Sub - Bass low end sound 6x9's - Mid sound Tweekers - high end Chavs have a horid habit of setting up amps/head units wrong. Headunit should be set to a nice level sound, as thats just the output signal NO EXTRA BASS! THe sub can handle itself, it'll do ALL the bass. 6x9's should be coming from the head unit, and running all you're mid, they shouldn't have any bass really, nor much high end. The tweekers should be setup just for high end, so mostly vocals or high pitch sound. A low pas filter for the sub, and hi-pas filters for high speakers. Having all 3 would give y
