I have been asking the same question since 1991. On my 91, I used OEM speaker housing, sealed the ports and installed 4? 4 ohm speakers. Then, I bought a pair of OEM speaker housings from 84-89 which mounts inside the doors. Again, replaced Bose speakers with high quality 4? 4 ohm speakers. I dropped in a pair of 6.5? speakers in OEM locations, again, plugging the ports. Also added a pair of 10? subs all fed with Sony 6 channel amp. This amp was controlled with Alpine 767 head unit and Alpine DSP. Also had a 6 disc changer. Let?s not forget behind rear view mirror. An Eclipse front firing center channel. Sounded pretty good but a lot of wiring and weight.
Challenge was front passenger side due to door panel curving into the dash. Ended up drilling 1/2? diameter holes in circular pattern to allow 4? speaker behind the door panel.
My current system with Pioneer Avic BT140 connected factory speaker/amp with 100 amp Bose amps from similar era Cadillacs augmented with 500 w90s vintage Alpine amp for one 10? low profile sub sounds far better and quite a bit lighter.
I think about adding a pair of 5.25? speakers in early C4 housing in the doors. If I do this, I?ll be trying to create a custom metal grille to replicate the curve on the passenger side door. I think it can be done but a lot of meticulous fabrication.
Ideal would be a pair of 8s in the door but there is no place in front of the car to do this.
