see with factory speakers they give crappy frequancy response so i would figure that.... most people dont know what good sound is and car systems put into cars today are good for standards they had in 1985.......(meaning factory premuims) i suggest you go listen to a shop or 2 near you that does hi end to get an idea..if one isnt close by look for an iasca show...if that isnt avalible go to a stereo store that sells higher end home stuff..basically the same type of sound
