Hi all, I have an 01 AWD and the stock amplifier is going out on it (as least that what the dealer service mechanic said...)I have an aftermarket head unit installed for a while now and thinking of just removing the stock amp and do without an amp for now.  it's probably better than hearing the static noise in the speakers that gradually gets louder when the engine is reving up at acceleration.
Does anyone has instructions on removing the stock amp and reconnect/splice the speaker wires at that junction?
thanks,

From what I understand, the stock amplifier is located on the passenger side rear compartment behind the trim. now as far as removing the trim is, that my friend seems to be another animal. I'm hoping someone has done this already, as in remove the rear side trim to replace the 2 rear compartment speakers for those that have that option, I plan on removing all stock speakers and radio in the spring and install a nice custom setup with replacing those 6x9 rear with some subs.......

The stock amp is actually located on the firewall above the ebrake handle.  The back speakers are actually a separate 6 or 6 1/2" midrange and 4" full range speaker on each side and not a 6x9.  The entire backside panels need to be removed to do so.  You cant simply just remove the speaker grills as there are speaker enclosures behind them.

When you remove the speaker, doesn't that destroy it? I tried lightly to remove it, but stopped a I did not wanna jack it up, cause I know finding interior parts for our trucks is not an easy thing...

I seem to remember that GM called it a 360 watt system.  Not certain though.  The amp has no user adjustable settings.  When I had my Tek, I planned on putting better Pioneer Speakers in the back.  I purchsed a set of 6 1/2" 4 way speakers and a pair of JBL 4".  When I put the 6 1/2's in, they only played Mid's.  So the OEM amp is crossed over to only allow mid-bass through there.  The 4" JBL's were much brighter on the highs.

If you plan on changing the system, you will need antenna adapters, an interface for chimes (ie seatbelt reminder, turnsignal on reminders etc. as the sounds are generated by the radio and played through the front left speaker.  If you have Onstar- yes, there's another module needed.  Oh, and I don't know for certain, but I think that you loose your steering wheel and rear cargo controls.  

I added an Infinity BassLink in the back for a little more bump and fill.  Self amplified 10" sub in a small enclosure.

did you take out the speaker or try to remove the grille?  The speakers will come out- In fact I have 4 of the door speakers from a standard, non 10 speaker system in my garage.

The entire rear cargo area needs to come out to gain access to the speakers.  Thats, all of the cargo hooks, the trim panels on the back floor, and I don't remember, but maybe the seatbelt bolts too.

Actually I was talking about the grills actually, I have yet to get to the speakers themselves, as what I feared is imminent. I prefer to just remove the grills but as I said before, I think thats just going to destroy the grills. I plan on putting a custom 6" or 8" jbl's subs on that spot using a good 5 channel amp. Probably a alpine pdx-5 or somewhere along those lines

I am actually planning on doing the same thing. I plan on removing those rear speakers and putting a custom 8" or dual 6" subs on each side. I would prefer to go with JL's though, as I had a 6" jl in my previous car before my family grew, my beloved 2000 Audi A4 1.8T, this had a stock 6" sub that you did not notice until you put your ear by the rear side trim and feel vibration. I did not know until I had the car for 4 months  Shocked Anyhow, my project this spring will be to remove both rear panels to size up the projest and to see what it needs and all.........i'm going to confirm where the stock amp is as I plan on getting a good 5 channel as well, and I wanna use the factory wiring to power the door speakers, this is one thing that GM usually dont go cheap on, speaker wiring is usually  pretty decent.

Howdy Folks.  I am so happy to have found this thread.  I am hoping someone here may be able to help me.  I just bought an Aztek the other day.  The rear most speakers have the controls on them and are labeled Pioneer premium audio, so I am assuming i thad that system in it when new.  WHen I looked at the car, the radio did not work, so the dealer tried sticking in an aftermarket radio, and much to his dismay, that did not work either.  I got him to let me have the origional radio, which I discovered today is probably not the original radio, but just some double din radio that someone along the way thought might be plug and play, and the aftermarket radio they tried installing.  The problem they had was you got great audio out of the radio right at the output terminals, but nothing out of the speakers.  At first they thought the speakers were bad, and took one of the doors apart to try to replace it, but the speaker in the door seems to be fine.  The odds of all of the front and back speaker wires and or speakers being defective seems pretty low.  I suspect this setup has an amp in it and the speaker wires going to the radio hole in the dash continue on to the amp, and than to the speakers.  This would mean that either the amp is dead or the amp is not getting power.  Is there a wire in the radio harness that needs power to turn the amps on?  If the amps are defective, is it hard to bypass them?  I would not want to have to run new speaker wires to all of the speakers.  This is the only site I have been able to find that seems to have a clue as to the audio options in an Aztek.  Any thoughts or ideas are appreciated.

Welcome to the forums... Such as they are.. Unfortunately, this forum has almost but died. Most everyone that use to post here has moved over to the FaceBook Pontiac Aztek Club..

https://www.facebook.com/groups/207147849401250/

If its not the right radio, it may not be sending out the right can-bus signal to the amp. You would have to ask over on the facebook side to see if they can help..

Thank you for the feedback.  Sadly, I flat out refuse to use facebook.  However it was not raining out this afternoon so I went out with my ohmeter and a AAA cell and did a lot of checking things.  I have no idea what is up with the amp.  It may not be getting a turn on signal, or it may be cooked.  I can not rell you how dumb I think GM was for not making the input and output of the amp on compatable connectors so if you wanted to bypass the amp you could just plug the two of them together and be done with it, but I digress.

So an afternoons worth of orobing has got me this.  Sadly without seeing the speakers I can not get the phase (+/-) of it.  But here is what I got.

24 pin connector on radio   24 pin connector on amp  Notes
2                                           7                                         Right Front drive from head
3                                           8                                         Right Front drive from head

14                                        11                                        Right Rear drive from head
15                                        12                                        Right Rear drive from head
16                                        6                                          Left Front drive from head
17                                        5                                          Left Front drive from head
                                            1                                          Left front door speaker input
                                            2                                          Left front door speaker input
                                            3                                          Right front door speaker input
                                            4                                          Right front door speaker input
                                            13                                        Left rear door speaker input
                                            14                                        Left rear door speaker input
                                            15                                        Right rear door speaker input
                                            16                                        Right rear door speaker input
                                            17                                        Right Tweeter input?
                                            18                                        Right Tweeter input?
                                            19                                        Left Tweeter input?
                                            20                                        Left Tweeter input?
                                            21                                        Right hatchback speaker input
                                            22                                        Right hatchback speaker input
                                            23                                        Left hatchback speaker input
                                            24                                        Left hatchback speaker input

Notes:  The drive polarity on the radio connector should be the standard and it should follow the wires I ohmed out to the amp connector.  I was working alone so I am not 100% sure of the right/left of all the speakers.  I was working under the drivers side of the dash while figuring them out.  You can check the polarity if you have a helper.  Use a coupe of pieces of solid hook up wire and stick them in the connector pair for a speaker.  Say pins 23 and 24 on the amp connector for the left hatchback speaker.  have a friend GENTLY insert something stiff through the grill until it touches the speakers cone.  Do not poke through the cone, and do not hold the piece firmly in your hand.  Now put a small AA or AAA battery across the wires to the speaker.  In one direction the battery will make the speaker cone extend out.  The plus terminal of the battery is going to the + terminal of the speaker.  If the speaker cone "sucks" in, the + terminal of the battery is going to the - terminal of the speaker.  Note that as soon as you disconnect the battery it will retreat back to the "center" position.  You need 2 people to do this, one to work the battery and one to watch the speaker.  On the radio connector I did not elaborate on all the other stuff that is there.  This is just the speaker wiring.  Also note that you have 8 speakers if you count the independent tweeters.  You may want to series or parallel some of them together.  From my tracing the hatchback speakers seem to have the best bass response so I am thinking of joining them with the back door speakers, unless my radio has a sub out, in that case I may hook them to that.  I need to have a look at the aftermarket radio.

I hear ya on FaceBook. But it seems to be the only source for live information. This forum is all but dead, and we get waves of spam from time to time. Forum mods arent even here anymore.
