I just finished doing a complete sterro upgrade on my 98' LSC. I personally installed a Kenwood Cd / MP3 / IPod /etc. head unit, (4) 6 1/2" Alpine mids, (4) 3 1/2" JL Audio Tweeters / Highs, a 1000W RMS Alpine amp and a DVC 10" Alpine type "X" sub. I did all of the work myself, one peice at a time, in the above listed order. IMHO, the stock speakers are s*** and I can't believe that JBL actually allowed Ford to use their company name on those supremely sub - par speakers. The stock amps, however, are actually pretty good. They are all that is powering my (8) in car speakers, (the amp is for the sub only) and the volume and clarity is unbelieveably acceptable. I would leave the stock head unit and upgrade the speakers if my budget only allowed for one or the other. Like I mentioned earlier, I did ALL of the work myself, and recently at that, so if you have any questions about fitment etc, please feel free to shoot me a P.M.
