I'm not sure about you, but my rear 4" speakers are what provide the bass to my car. (Well did before I added the bazooka tube) The reason that the factory head unit would sound best with the stock speakers is because the head unit feeds into the amp (behind the glove compartment) which has crossovers and delivers the high to the tweeters, lows to the woofers, and the mids to the midranges. Replacing the speakers will help with a non-factory head unit, if you bypass the amp, but with the stock head unit, replacing them will just make the tweeters built into the speakers inoperable and not function properly. I put a Boston S55 set in my kickpanels and only the woofer works (though it sounds better than the stock Nokia's). |
