hi the subwoofer in my fiero has never worked and the woofer is brand new.. but how sould it be wired to my sony headdunit? the guy that had the car before me just left it plugged in like stock... but what do i need to do to get it to work?

idk but you have it back on the road?! ?

no not yet, it actually went to the shop on the rollback last night.. i told the mechanic that i thught it was the throwout bearing, but just install a clutch kit while he was in there and to check out the hydraulics since the piston shot out of the slave cylinder, it should be on the road by wednesday depending on how fast he works

The stock amp uses all speaker leads as it's high level input.
This might help:

sooo basically i should trace the wires from the subwoofer and figure how to wire it into the new headunit?

Not entirely.
The power is at Amp connector pins 3 & 13 (positive) and pin 14 (ground). Check with an VOM and see if it is. The Amp is in the center console near your left calf when sitting in the passenger seat.
If the New radio was installed without a harness adapter, the wires may have been cut and left out, which would require removal and inspection behind the New radio.

the guy that did my radio before i got my car used an adaptor thing that he spliced into the stock harness leaving the stock plug on it, can anyone tell me what color wires that the subwoofer wires should be going to? cuz it seems that the woofer isnt spliced into the new plug for the head unit..??

If that is what he did, you have to make sure the power feed for the sub amp is fed by an ignition source - on the original radi the sub amp was power by the power antenna output, but new decks do not provide enough current to turn the amp on.

Looking at the above posted diagram you have 2 pink wires that power the amp, you MUST connect them to IGN power.

so basically if i get power for the amp my subwoofer will work? where should i run the pink wires to?

There is an IGN source it the above diagram...key on = power

sorry for all the stupid questions, i cant really look at my car and tell since its in the shop but will one pink wire be to the ign and one be grounded or both to the ign?

quote Originally posted by dmcgreene: wait nvm. now i see that these are both positive, can i use the ign power source for the headunit for these wires?

yes

okay then ill try this as soon as my engine is put back in my car and is driveable

thanks guys wired the two pink to the ign/accessory wire and the subwoofer worked 1st try

I'm currently hooking up a Sony head unit to a stock sub. If I'm not mistaken, you are saying that the ANT REM (.1A max) and the AMP REM (.3A max) of the head unit is not powerful enough to drive the stock sub amp.? That I need to hook up to the IGN/ACC wire to the two pink sub wires (pin 3 - mute, and pin 13 - battery)?

Thanks in advance for your help.

im not entirely sure, i knoiw that the previous owner hooked up my headunit, it worked the amp just wasnt getting powered, ended up un hooking it cuz it kept draining the battery
