Hi everyone: Reaching out for some ideas & suggestions. I have an 04 T/B Ext. with the factory CD/Cassette Audio System (non-Bose). Based on other Delco systems I have owned and systems I have heard, I come away disappointed with the sound system in my T/B. The volume, bass and treble tone are all good, but it appears the system lacks sound clarity/sound separation. I have tried adjusting the bass, midrange and treble with no success. I was thinking of upgrading the speakers. I am curious to know if someone is using an upgraded speaker with the factory sound system and what the results were. I'm looking for plug & play possibilities only as I don't want to modify and/or cut. Any ideas/suggestions???
