I got a little curious today and tried to see if I could mount a set of Pioneer 6X9'* in the rear passenger doors. It was a tight fit, and after some pounding with a BFH, some drilling and blood, I got one in. Had to stop early so I can get this posted and get ready for work.
Here'* a couple of pics....

Here you can see a slight gap between the speaker and the door panel. I'm going to try and fix that tommorow when I do the other door.

After I got it mostly installed, I ran a jumper wire from the L rear speaker and hooked it up. Cranked the stock stereo up and it sounds really good sitting in the back seat.

Next, I need to install some volume controls for those door speakers. Maybe mounting something in the ashtray of each door so that the audio level can be controlled by the passengers.

Ok,,, thanks! I hate it when it does that.
Ok, now that I have someones attention, what about using amps on this setup? Total of 6 speakers here in this car. What am I looking at for using amps? What would be best in hooking these door spks into? Back spkrs or front spkr feeds? I don't have a sub in the trunk. Trunks for guns and fishing gear. lol.

Well now that you've wired the rear doors in parallel to the rear speakers...you've lowered the impedence on those two channels to lower than likely what the stock stereo is designed for; ie. less than 4 ohm. Yeah, it'll probably work for a while, bit its horrible on both the source equipment and the speaker. The radio'* outputs will likely over heat and burn up prematurely, and due to the lower impedence and harder working outputs in the radio the audio distortion (THD) will be signficantly higher. Aftermarket amplifiers that are designed to power channels at 2 ohms usually list a THD increase several dozen to several hundred times more as opposed to a 4 ohm load. I imagine in the case of a factory audio system, the increase will be on the extremely high side. If you like the way the extra speakers make your audio system sound, they need to be on their own channels of an external amplifier to prevent damage to your stereo, and to ensure cleanest signal to all of your speakers installed.

So, on amps... should I get a 4 channel for the existing factory system, and then another 2 channel for the additions? (Remember, I'm not looking for alot of boomin noise here. Just something with some more punch).
Thx

I just finished installing the 2nd speaker. I ran temporary jumpers from the rear deck speakers. (now disconnected) and gave it a test run. BOY DO THEY SOUND GOOD SITTING IN THE BACK SEAT
Here are some more SMALLER PICS for you to enjoy.
It was hell trying to measure the left speaker because I slapped it in without taking measurements. Which made the right one difficult to line up. All an all, it came out to within about 1/8". Not noticable, unless you were looking for it.
If anyone is wondering, I did try the bottom of the door. I could have, but I didn't want to cut the door and jeopardize the structuralbility(sp) of the door.
Also, pay no attention to the primer on the doors. Thats another project.

My old 94 SLE, which is now for sale by CSFiend and can be found in the for sale section.
I used 4" infinity Kappa 2-ways, but I only had 6.5" covers.
