Wire up mid speakers - Monsoon
Wire up mid speakers - Monsoon Awhile ago my middle speakers blew (the ones by the rear seats). So I just clipped them and threw them out. Today I was trying to put new speakers in, and I cannot figure out the wiring. there are 4 wires going into the clip, and I used a meter to find pos/neg and hooked that up, leaving 2 wires free. The speaker didnt work.... Im not really sure what to do. Anybody know what the problem is? I dont have the original clips anymore, because I left them attached to the old speakers when I threw them out.

The sail panels in Firebirds with Monsoon systems have dual voice coil (DVC) subs. The DVC setup is the reason for four wires instead of two but the fact that they are subs and low-pass filtered from the amp is probably why you're not getting sound from your aftermarket speakers. You'll have to rewire to get any midrange or highs from those speakers. The easiest way is to disconnect the hatch speakers and pull those wires forward to the sail panels. Or, you can install subs like the ED EU-700 there and use the factory wiring.
Here are the wire colors for the sail panel subs in case you need them:
Left side:
Tan +, White -
Dark blue with white +, Light green with black -
Right side:
Red +, Tan -
Dark green +, Light blue with black -
Both pairs carry the same signal so just make sure you keep the pairs together if you use them.
Don't mean to steal the thread....but...here goes..
Just got a 1998 Trans am this weekend..and its full of problems...
One of them though, is the stereo. It sounds like crap. Bad sound was coming from the speakers by the rear seats. So i figured they were blown. There were aftermarket 3 way speakers in those spots, and all the wires had been used. I did not realized these were for subs so tried a pair of my new 6.5s in there and the too sounded like crap.
After reading this post i realized that speakers like my 6.5s or the ones that were in there probably will not work well the way its wired right now.
Correct?

An increasingly popular choice is the Elemental Designs eD 7Kv.2 (formerly EU-700). They are a little deeper than stock so a spacer is required for installation but they wire right up to the stock wiring and they provide a significant improvement in sound. There is a recent thread here that provides details of an installation and also links to a longer discussion in an earlier thread.
soooooo, if I dont want to mess with expensive DVC woofers, a single voice coil woofer using just 2 of the wires should work (the real issue being that the amp is cutting out the high range?)
the weird thing is, if I touched the other two wires to the speaker terminals while it was wired to the original two i used i got sound (all ranges).

Yes, certainly you can install an SVC subwoofer and just use one of the two pairs of wires. Your output will be somewhat reduced but it shouldn't be a problem. I'm just not familiar with many quality 6.5" SVC subwoofers that are also inexpensive.
You also have the option of replacing with stock speakers. The stock speakers aren't that bad. Yes, they're made from cheaper materials and won't last forever but the biggest cause of blown speakers in a Monsoon is distortion from the stock head unit.
