I've searched around a lot and Can't find a case of anyone trying this before. I want to have both my headrest Speakers and B pillar speakers wired up and have a switch to change which set I want on. The closest thing I could find was a wiring diagram like this from Scrapyard Electric
Does this look like it would work? And Could I wire up both sets of headrest speakers (as in both left speakers together and both right speakers together) together in series without overloading anything?
This topic will be of great reference to me! Years ago I physically installed the speakers & girlls into the pillars, but never got around to wiring them up.
... And Could I wire up both sets of headrest speakers (as in both left speakers together and both right speakers together) together in series without overloading anything?
Overkill to have all that running at once (you still only have 2 ears) ... but okay...
Scroll down to Parallel/Series wiring (Section 38) http://bcae1.com/
Oh, I think some have misunderstood me I want to have the switch in place to have EITHER the headrest speakers OR the Pillar speakers. I'm and Audio/Lighting tech student at Wayne State and I'm 90% sure that having both sets running would give you some weird phasing, but I've never dealt with anything like this before lol. I'm going to keep researching....
would there be a problem having all 6 of the speakers sharing the same ( - )? as you can see in the original switch wiring I threw up there, all the speakers share the same ground, and only the ( + ) side of the circuit is switched between speakers

No problem. Problem would come using them at the same time which would put the speakers in parallel doubling the load on the stereo if the speakers are the same ohms.
Ayup, but all those cars have a lot more cabin space now don't they.

True, but how many does the Fiero NEED? 1? 2? 4?...
"A large number of speakers makes a lot of sense. Since you sit very close to the speakers by default in a car, using more smaller ones instead of less lager ones will give you a more homogeneous sound field for all passengers with the same volume capabilities as the aforementioned system. I just saw a drawing of the Burmester (German high end audio manufacturer) speaker system in the Porsche Panamera. The sheer amount of speakers will give all passengers a great listening experience while the single drivers are pretty small and thus non-intrusive."

seeing it originally only had 6 I would say those 6 would be more than enough and give ideal listening quality to Both passenger as Fieros only have the seating capacity of 2. I liked the setup in our 84 with 6, 2 in each seat and thought the sound was good, lots better than our 86 SE with only 4 but that's just my opinion. if I remember right all the manufacturers spend a lot of money designing their radios and speaker placement with each vehicle. larger vehicles with more seating capacity would naturally need more speakers in more places but how many and where depends on the vehicle and places available to put speakers as well now doesn't it.

The best sound is going to come from having the left and right speakers equal distances from your ears. The headrest speakers are as close to perfectly spaced as you're likely to get. The subwoofer, if so equiped, is omni-directional and therefore functions fine as a single driver in just about any location. The dash speakers are not the same distance from your left and right ears but the front-to-rear distance of them to your ears lessens that problem. The passenger side speaker is about 2x as far from you as the driver's side.
The B-pillar speakers have the worst placement problems of all these. One is right by your head and the other is right by the passenger's head. One is about a foot away and the other is about 4-5 times as far away. If you try to balance the sound so that your right side equals your left side, the passenger will get blasted by the right side and completely lose the left side.
You will lose stereo imaging if you go with B-pillar speakers. If you try to use headrest and B-pillar speakers together (I know you said separately) you will not hear the passenger side B-pillar speaker at all. Your passenger will not hear the driver's side B-pillar speaker.
So really, B-pillar speakers are a compromise at best and any attempt to create a "sweet spot" for yourself will ruin the sound for the passenger. If you have headrest speakers, stick with them or upgrade them. You'll be hearing the music as it was meant to be heard.
Yet a lot of cars on the road today have 6, 8 or even 10 speakers or more in them. I would hook both sets up.

True - because they're likely components to separate the frequencies - not all full-range speakers.
This loaner I'm driving has tweets in the dash and mid-range/mid-bass in the fronts doors. Then 2-way full-range speakers in the rear plus 1 sub-woofer.
My GT has 13 speakers in it.
FRONT STAGE (where you want your music to be) is : Left (T/M/MB) Center (full-range) Right (MB/M/T) 7 speakers, but 3 channels (left, center, right) - and count as 3 "speakers"
Rear Fill is: T/M on a 4"x6" plate each side. 4 speakers, but 2 channels (left, right) - and count as 2 "speakers"
Plus a 10" sub behind each seat - not separate channels per se, but low bass extension of the left/right front channels

The reason for many speakers, is not so much for volume, but for quality sound, remember the speakers in a Fiero are tiny.. they don't reproduce music at anything past modest volume.. but if you add extra speakers, the load per driver as same volume is a lot less, allowing them to reproduce the signal much better.. Ideally the head rest drivers should be mid range only.. and a good set of mid drivers, and a quality amp.. with the pillar speakers more of a mid highs as neither spot/size drivers are good for any type of low end.. the drivers are to small.. yes some have made systems in the oem that use tiny drivers with a sub.. or tiny drivers with long ports (bose comes to mind) . honestly I'd like to try a set of head rest sized drivers 3.5" installed backwards with the driver cone and grill facing the rear window.. allowing the sound to bounce off it.. instead of the sound right beside my ears.. as most 3.5" drivers are very harsh at the mid to upper range.. unless you spend some bucks..
I wired in a set of 85 seats with speakers into my 87GT. Eight speaker system. I seldom play music and normally listen to talk radio. The 8 speaker system does make a difference in the fidelity. I didn't wire in a separator switch, but if you really wanted to, it wouldn't be difficult to do it with a DPDT switch.

Porsche had a remote fader knob that they wired externally on the Porsche 944 back in the day. I used to own a Porsche 944, and ended up replacing the factory radio with an OEM looking Blaupunkt that could play CDs, but didn't look out of place. Anyway, I added an additional set of tweeters in the car (in the back), and i used the fader to basically adjust the gain between the rear speakers, and the tweeters. When the knob was in the middle (with a divot so you knew you were spot-on in the middle), both speakers got equal power. When the knob was in either direction, it would decrease power from one, and increase to the other. At the utmost extremes, I could disable the tweaters and give full power to the rear speakers, or disable the rear speakers and provide full power to the tweaters in the back.
Assuming you set up the ohms and wattage correctly, something like that would work really well.
