Ok, here'* my dilemna - I just replaced my rear 6x9s with some pioneer 3way 6x9s. Do I now 1. replace the front with 5 1/4 components 2. replace front with 5 1/4 mids and use stock tweeters as well with a 4 channel amp or 3. put a sub in the trunk ? If I were to amp all 4 speakers, how do I do this with the stock head unit?

Thanks

I'd vote for subs if you can good ones with proper enclosure and amp to power it.. if not.. then I'd go with the front and 4 channel. If you want to keep the existing head.. there'* something Crutchfield sells that you can use to tap into the speaker wire that will drop the voltage down to safely convert for your RCA for your amp.. dependin on the amp you get.. you should be able to rig it up so the fade will still work from your existing stock head unit.
