AC Delco Audio Help

[ps200sx]

My 93 Trans Am has the AC Delco 6 speaker system in it, the amp is located in the passenger side rear sail panel.

When i got the car i replaced the cheap nasty stereo the previous owner had fitted with my Pioneer. Got the wiring colours from someone on US forum.
All seems ok, but hoped to get the sail panel subs working which were previously also not working.

Left it for a few months while i was fixing more importiant things until today where i decided to pull of the passenger sail panel to inspect the amp and check the sub on that side at the same time.


The amp seems fine, looking anyway. Wiring all looks fine, no cuts or joins. Looks all stock.
The sub also looks in great condition.

Tryed the stereo, no sound from sub. Played about with a few settings on it, still no sound from subs.

Thought maby the wiring could be broken or cut to the subs elsewhere, followed the loom right up to were it dissapears under the dash. All looks fine.

Decided to try and unplug the block connector from the Amp and turn the stereo on. Expected to hear nothing, but got sound as normal

Now im totally confused...all the wiring at the HU end seemed stock, the connector block had been cut off but all the wire colours matched up with the info i got.
Every speaker works apart from the sail panel subs, but even with the amp unplugged everything works the same.....

Have i missed something??

From what i heard elsewhere the amp may only power the sail panel subs and i should be checking the amp fuse or the amp turn on wire at the HU end.
Does this sound right? And if so is the fuse in the main fuse box or on the amp?
Anyone know what colour the amp turn on wire is?

Loving the new forum btw, and i have the first post in this new section woohooo!

Any help would be great.
Thanks

Is the amp powering on from the headunit you should have a remote turn on lead going to the amp?

[ps200sx]

Can't tell if amp is getting power but got a feeling its not since unpluging it made no difference and the sail panel speakers make no sound at all.

Been looking around other forums aswell, think i do need the remote turn on lead and got a feeling ive not hooked it up to the head unit. You don't happen to know the colour of the remote turn on wire do you?
Have read somewhere its a blue wire and seem to remember a spare blue wire behind the stereo, not 100% sure what i read was for the speaker system in my 93 though.
Gonna try and hook it up tonight on a hunch but would rather have conformation that its the right wire to hook up to power incase im wrong and damage something

On my 3rd gens and my 2nd gen the blue spare wire is for the power aerial?!!

[ps200sx]

Blue has been the power aerial on other cars ive owned, but as far as i know pink is for the power aerial on my car???
Had a quick look on my lunch break, seems i have a spare pink and a spare blue. Will have a better look when im finished work.

Connected the blue and as far as i can tell has made no difference, should i mady try the pink??
Any ideas??????

Cheers

What wires are going into the amp. Is there a pink or blue? I take it you know the right wire coming out of your new headunit?

Theres sooooo a joke in there

I dont "suppose" it will do any harm connecting it, if its for the aerial the worst that will happen is the aerial will go up....or a fuse will blow....i think

Be worth trying to pick up a Factory Service Manual from http://www.ebay.com/motors I got one for my car and its got superb wiring diagrams and fault finding.

Problem solved!!
So chuffed, what a difference!!! To think i fitted that stereo a year ago and put up with really tinny crappy sound until now. Now ive got great tight bass and amazing clarity.

What it was, was when i removed the old cheap bodged in stereo the connector block had been cut off.
Managed to get a wiring colour guide from a forum somewhere which was just the basic connections.

Had left over after wiring it all up, a gray wire, a blue wire and a pink wire.
They had all been cut and taped back.
As far as my wiring guide said:
GRAY was "illumination" Dimming the display at night (strange though that another wire was also this and works!)
PINK was electric aerial
And BLUE i never got a any info on.

Wired in the blue to the ignition switch wire on the Head Unit this afternoon, got nowt.
After work thought sod it ill take the blue out and try the pink wire....instantly mega bass!!!!!

So to any 4th Gen 93-97 owners with the 8 speaker AC Delco/Bose audio system who have aftermarket head units fitted, and get crappy sound as well as the sail panel speakers not working.
Tap the PINK wire at the head unit end into the ignition switch wire of the head unit wiring loom.

Problem Solved! Great Sound

Thanks for the help
