"DYNAUDIO Upgrade".

Heh. You've noticed that we can't modify the doors worth a damn.

After screwing around with the car since 1999, ultimately, I installed a Dyn System 360 by removing the dash pad and the factory tweeters and cutting enough out of the plastic dash box to let me drop in a pair of MD150 silk-dome midrange drivers through the removable tweeter grills, then drop the dash grills back in place.

The advantage of the Dyn silk dome drivers is they are very omnidirectional. I have them aimed up at the top of the windshield and they still sound amazing.

The drawback to the System 360 is the midbass driver is huge on the back and just won't fit into the door without significant changes. So, I found an Alpine midbass driver, part of a system with a separate tweeter and crossover (trashed them, BTW) that dropped into the plastic stock speaker supports.

The Dyn midbass drivers got mounted in smallish boxes and hung from the package tray. Tight would be a good way to describe the bass response and I still have trunk room left.

bought a house before I finished the project. The car looks terrible with the tweets rolling around on the dashpad instead of being mounted in the A-pillar covers like they should be. I was afraid of aiming them at each other across the dash. But, it makes sense mechanically and due to the incredible off-axis response of dome drivers, they still sound great.

I definitely didn't use the factory wiring harness. The round electrical connectors are not extra-wires-to-the-doors friendly. Either run the wires outside the connectors or.... I took some bare 12ga solid copper house wire and threaded it through two unused pin holes on the round connectors. Slid insulation tubes back onto each end, then soldered speaker wires on.

Driver door hinge is going out, so I'll have to take that apart to take the door off. But, despite not being oxygen-free-copper all the way through, it works and it has been dependable.

If you do decide to cut holes in the plastic pillar covers, see if you can get replacements from a salvage or Ebay.
