I just got the car and I see a place for 5 speakers. But I have two in doors and one in the back. The head unit has been replace with a sony. is there a Factory amp? for the front speakers Is the one speaker in the back a Sub.? and dose it have a amp or dose all the speaker get there power from the head unit.
I have gotten 4 new 6 1/2 speakers. can I put the 4 speakers in and still use the sub?

Thanks

 

it probably had a bose/monsoon system and so the prev. owner bypassed the amp by removing the old speakers and deck and running new wires to the speakers, probably didnt replace all speakers because of cost (who knows) but thats my thought.

 

It came from the factory with the BOSE system which was a 3 speaker system until 95 or 96. The rear speaker in these systems is a full range speaker the box design just helps it put out a little bass. In this system each speaker had it's own amp. Supposedly the BOSE system uses some kind of abnormal level of preamp input for it's amps so they say you arent supposed to hook up the amps to a aftermarket unit. They sell a conerter to go from speaker level output the the BOSE level input, so there maybe a converter installed. I replaced my sytem soon after I got my car and ran new wire to the doors and I installed speakers in the rear side panels and had to run those wires as well. About 2 years ago while looking through my tech manual and looking at the wiring diagram for the BOSE system I decided WTF and wired up the rear speaker to some rca style plugs and hooked them upto my preamps on my head unit. It's been working fine for the past 2 years or so no problems at all! I have an equalizer installed between the headunit and the rear speaker so that i can decrease the mid and high signals as well as boost the bass signal. Plus the head unit i have now has SUB-Preamps so I can boost that from the head unit as well.

 

Thanks, I am installing new speakers and rewiring in the door and the sides panels also. My head unit has RCA outputs so you ran that to the amp. in the back? sound like what I like to do. Again thanks for the info.

 

I picked up a 94Z last fall and yesterday I decided to look into replacing the back speaker that had been taken out. It looks like I have some sort of convertor installed in-line (long, rectangular box ~5"x1"X1.5") with wire lugs on one end and RCA jacks on the other. Any suggestions on what size(dimensions) and power range the original speaker was? I'd like to restore it to near original condition.
And if I understand you correctly, I will need the convertor if I DON'T replace the speaker with a Bose speaker, right?

Thanks for the info.

 

I checked where my rear speaker was originally housed and found an AudioLink Powerlink II - speaker level to RCA converter. I'm assuming that the previous owner had amplified subwoofers in the back that were removed before I bought the car.
My question is, can I remove the converter and use a standard , off-the-shelf non-Bose speaker or do I need to go with a self-amplified speaker?
