Sound System
I upgraded the sound system in my 93 LE using the following components:
o Sony MDX-C7900 Head Unit
o Pioneer GM-X652 Amplifier
o MB Quart DSC-213 Component Speakers
o Pioneer headrest speakers
o Bass tranducers (shakers) in seatbacks
When planning the system, my design objective was maximum bang for the buck. The final total cost of the system was somewhere around $500. This figure includes the amp, speakers, head unit, and wiring. The headrest speakers and bass shakers were retained from the factory system. I had purchased the head unit about two years earlier, so it wasn't really part of the current investment.
I couldn't be more pleased with the results. The sound is crystal clear, with decent imaging for a mobile system, and tight, punchy bass thanks to the bass shakers and plenty of power for the capable MB Quart's. I now actually prefer listening to my favorite music in the car rather than at home!
A wiring diagram is provided at the bottom of the page for anyone interested. In order to maximize control over the relative volume levels of the headrest speakers, bass shakers, and door speakers, I made use of the head unit's amplifier to power the headrest speakers and bass shakers. This allows me to adjust everything independently without having to invest in more equipment. The head unit's power output is more than sufficient for its task. In practice the headrest speakers are of minor importance compared to the door speakers and bass shakers.
Future plans include fabrication of a custom cover in the trunk. Right now the trunk is rendered useless because items stowed there would damage the wiring connectors at the amp. The cover will give me a place to keep my luggage. It will probably also incorporate a small fan to prevent overheating.
Here are some photos.

Here is the Sony MD head unit. MD rocks!
You can fit 10 MD's in the glovebox with plenty of room left for all kinds of other junk. Those are my Bilsteins on the floor, waiting to be sent off for a rebuild.
The amp kind of dominates the trunk.

My power cables made from doubled runs of speaker wire. They work perfectly and cost less than $1.
