Speakers
EDIT:
Turns out I lied about the speakers being factory. I just couldn't tell from the front ones, so I assumed they were factory and never checked the back ones. Front ones are JV Audio, which explains why they're bad, and the back ones are pioneer.
Now, the real question I have is: Can 6.5" speakers fit on the front, if it's a bose car?
So, my sound system in my '88 coupe sucks pretty hard. I already have a pioneer deck installed, but I'm not sure if the speakers are still factory or not.
Point being, if I were to upgrade the speakers, what are the sizes? I hear the front are 5.25, and the back are 6.5, but I thought there were 6 speakers? Dash, doors, and trunk?
I'm going to go outside and find out if they're factory.

Turns out the speakers are, in fact, factory. And the local police are insufficient. It's 1:40 AM in an apartment complex, I'm dressed in all black, crouched next to a Corvette holding a screw driver, and the police drive by like nothing's unusual.

I have an 85 and replcaed all 4 of my speakers. Getting the bose amp and casing out of the doors is a challenge but it can be done. I put 6.5" in the front doors and 6x9 in the rear. I rewired the speakers to an amp so I didnt get nasty distortion when I had to turn the radio all the way up on the highway with my windows down (no AC). You can use the factory wiring, just make sure you use the correct wires for the radio signal as the bose units have 4 wires going to them, 2 for the radio and 2 to power the bose amps.
Good luck

Just want to make sure on this. I did replace all of my wiring but left the original in place.
Correct me if I am wrong.

are you sure? I have laways been told the ohms are different on the Bose than most aftermarket units. They will work but may cause overheating of the head unit.

I dont know about the ohms. The guy that helped me with my speakers told me I could use the original wiring. I replaced the speakers first, drove the car about a week and decided I needed the amp that I bought and planned to oringinal put in. We then rewired all the speakers to the amp. The sound difference was HUGE with the amp. I had to turn the radio almost all the way driving down the street at 55 and the music was all distorted that way. I put in a Alpine headunit, Polk speakers with component in the from doors and 3-way 6x9 in the back hooked up to a 1400w Crunch amp. Sounds really good and clear, even down the highway at 70-75mph
The only thing I know for sure about the wiring is making sure the positive is positive to the radio and speaker otherwise you could burn out the amp in the headunit and/or the speaker

After more thought on this. You can use the original wiring but it is not recommended by a lot of stereo system wizards because it is a small wiring. But it is still doable. you can't mix match the head units and the original Bose speakers due to the ohm difference. It will work but not as efficiently. if the head unit is the same ohm as the Bose speakers it is OK.
There are places that sell Head Units that are compatible to the original Bose setups though.
I'm going to do some more research on this just to satisfy my curiosity.

Here is a nice write up on the C4 audio system upgrade.

I have a friend who can get me discounted speakers, but the vendor only has 6.5" rounds, and the 6x9" rears. So I need to know if the 6.5" speakers would fit, or if I'd have to go find them someplace else.

What fiberglass did you need to trim, and how hard was it to do? What tools did you use?

Here is the mount I made. The top is shaped to match the door.
Mount, just before fastening with sealant and screws.
Mount fastened and overhanging fibreglass trimmed with a router bit in an electric die grinder. Dremel tool or similar, would easily remove the overhang.
I used the bose box and cover, as templates for using the original screw locations.
