I pulled one of the front door panels off my '05 Sequioa today to have a look-see regarding Dynamat and replacement speakers.

Has anyone just replaced the factory JBL speakers in the doors using the stock wiring and amps? You obviously would need to make some modifications to fit new speakers, but it seems like that would be easy. It looks like a 6.5 inch or 6.75 inch component set would more-or-less just drop right in.

Granted, a new head unit and new amps and wiring would cure all, but I think if the mediocre speakers were upgraded, that would be easiest and least expensive improvement. Adding Dynamat while you have the door panels off makes a lot of sense too.

I'm not sure how the front door component system is setup. I know the tweeters are on top of the door near the A-pillars, but what are the speakers in the lower door? Is it a woofer & tweeter pair or a midrange/midbase pair? There doesn't seem to be any external cross-overs in the door either.
