- Two 4" dash mounted speakers (all models).
- The rear pillar (b-pillar) speakers are 3.5" (1987+).
- 'Sub' mounted under the drivers seat (optional in 1985/86???; all models 1987+).
Almost any 4" speaker will work. You just have to cut off two of the mounting tabs with a tin snips (bend them back flat) and they should drop right in and attach with the remaining two tabs. You then effectively convert it to the obscure "4T" style that is difficult to find these days. Alpine SPS-100A fit perfectly with the two tabs trimmed. Don't choose a speaker with a tweeter that sticks out, otherwise it will hit the grille. Also, try to stay with something under 2" in depth (not a problem with most 4"). A depth of 2" and over and the drivers side speaker will hit the structural bar in the dash.

Q: I played around with the tone controls. It sounds like it's *trying* to play bass sounds, rather than mid-range. Anyone know it's claimed the frequency range?
The woofer box is 6.25" x 7.25" x 2.5". You could put a bigger box under there. Around 7x10, and 3" deep. The floor is a little uneven down there, but that size *should* be okay.
