Still trying to get a after market head unit installed. With some great help in another thread we got some noise out of it, but only the rear part of the system is working no front speakers.

Looking at the Monsoon Wiring Information from the other thread it appears the amp needs two triggers, signal on power. We hooked up the regular blue with white stripe to the pink wire in the harness and did get sound. Nothing on the front speakers though.

Thinking if the amp does need two triggers for front and rear to work like the amp wiring shows here:

Link 2006-2008 Pontiac Solstice with Monsoon Wiring Information

----Harness side

Remote ² 20 PK 24 L.GN
² These two leads are labeled differently (PK is "Radio On" and L.GN is "Remote Radio Control") but both output 12V to turn the amp on.

----Amp side is states...

Amp Remote (Radio on) 3 PK*
Amp Remote (Remote Radio Control) 9 L.GN*
*Both of these connections receive 12V to trigger the amp.

In an effort to get the front speakers to work we think both the pink and light green shown on the amp end will need power or triggers. Not sure if we should split the blue with white stripe that currently goes to the pink to go to both connection we think need 12v or run another power wire to the light green wire or point.

If we swap the rear speakers using the rca jacks the rear speakers do play using the front feed on the head unit. So we are thinking the amp isn't fully powered with only the one trigger wire hooked.

Any advice on what is actually needed for power or triggers?

Hoped Santa would throw a fix on the car on Christmas, but he only took the milk and the cookies, left the Solstice with wiring still to be done!:)

The previous thread on our install is here http://www.solsticeforum.com/forum/f61/amp-dizzy-all-info-has-simple-answer-120041/

Really would appreciate anyone shedding light on this been a week now trying to figure it out!

One of the wires (probably the "Remote Radio Control") is a pulse width signal - NOT a straight on/off. See bolded part below:

2006 ACCESSORIES & EQUIPMENT Entertainment - Solstice

The radio supports the following signals:

. System Power Mode
. Infotainment Operation Allowed

The radio also supports the following GMLAN Vehicle Power Modes:

. OFF
. ACCESSORY
. RUN
. CRANK REQUEST

Radio Ground

A wire in the main radio connector that is connected to battery negative at all times provides the main radio ground. Resistance between the ground pin and the vehicle battery negative terminal must not exceed 0.05 ohm.

Radio Speaker Outputs

At low volume, the plus (+) and minus (-) speaker outputs circuits measure approximately 7-8 volts. If a plus or minus circuit for any speaker output is shorted to ground or voltage, the radio disables the circuit for component protection and sets a diagnostic trouble code (DTC). The radio sets the speaker circuit DTC on non - amplified systems only. As the radio volume increases the voltage on the plus and minus circuits change to create a voltage difference between each other. The difference in voltage is what drives the voice coil of the speaker producing sound.

Radio Head Unit Dimming

GMLAN signal data received by the radio determines the radio dimming and backlighting levels. The radio sets the backlight and VF display dimming to the value indicated by the interior dimming level and interior dimming display level signals in the GMLAN dimming information frame. The radio provides faceplate and control/graphics backlighting in the OFF (RAP inactive) when the exterior lighting virtual network (VN) is activated. The radio display is consistent then with the surrounding devices that use analog PWM dimming to backlight their control/graphics when the power mode is OFF and the park lights are ON.

Amplifier Interface

The main amplifier power is provided by a 20A RADIO AMP fuse located in the body control module (BCM). A discrete switched 12 volt output is used to control the power - state of the amplifier. To respond quickly to audio input and control signals, the amplifier is ON in all vehicle power modes except OFF and CRANK Request. However, when the amplifier is asleep it still must allow chime functionality. The internal amplifier bridges are fully powered and un-muted when the amplifier receives the switched 12-volt input.

The radio provides a remote amp mute output circuit to control overall muting of remote non-GMLAN amplifiers with rear seat audio (RSA) applications. The amplifier receives PWM signals on the circuit at varying duty cycle percentages for controlling the muted and un-muted functions of the amplifier. The RSA Enable circuit in the radio enables the rear seat channel muting of the amplifier. A Diag Sense circuit internal to the radio monitors the remote amp mute circuit for faults and sets the appropriate DTC when detected.

The function table below shows the four possible amplifier mute functions.

% Duty Cycle Out Function
---------------- ----------------------------------
0 % (Vlow Vdc) FOUR CHANNEL UNMUTE
50 % REAR MUTE (input must be 2-channel)
75 % SIX CHANNEL UNMUTE
100% (Vhigh Vdc) ALL_MUTE

Amplifier Radio Speaker Inputs

The low-level audio signals (LF, RF, LR, and RR) from the radio are the inputs to the amplifier. The amplifier boosts these inputs and outputs them to the vehicle speakers. If one speaker plus or minus low level audio signal circuit is open between the radio and the amplifier, the input to the amplifier is approximately half The speakers for that channel then operate at approximately half the normal volume or in some cases no volume.

The low level audio signals from the radio to the amplifier typically measure in the 4-5 V range.

Amplifier Speaker Outputs

At a low volume, the plus (+) and minus (-) speaker outputs circuits measure approximately 2-7 V AC or 7-8 V DC at the speaker connector when testing a normal working system. If a plus or minus for any speaker output is shorted to ground or voltage, the amplifier circuitry will turn OFF the front outputs or rear outputs for component protection.

Repeat speaker failure can be caused by a damaged amplifier. Test for a damaged quad bridge output in the amplifier if the wiring between the amplifier and speaker test negative for a short to voltage. Prolonged exposure to DC voltage can cause a speaker coil to short. An early indication of a shorted speaker coil is distortion/noise and eventual failure.

Remote Radio Audio Signal Inputs (UE1 only)

Audio output from the OnStar(R) communications module connects to the remote audio signal inputs of the radio. When the cellular telephone mute signal goes to 0 volts, the radio overrides any other audio signal and uses these inputs as the source for the output to the speakers.

Cellular Telephone Mute (UE1 only)

The OnStar(R) communications module uses the cellular telephone mute signal circuit to override the radio for OnStar(R) communication. When cellular telephone mute is not active, this circuit is held at 1-volt by the radio. When the cellular telephone mute signal is pulled to ground, the radio over-rides any other audio signal and uses the remote audio signals as the source for output to the speakers. If the radio was OFF when this circuit is pulled low, the radio will turn ON. Additionally, the radio fades the speakers to full front, adjusts the volume to an initial audible level, and sets an Auto Tone designed for optimal use with OnStar(R). When the mute signal is no longer pulled to ground, the radio returns to the mode it was in previously.

Component Description Antenna System

The antenna system receives broadcast AM or FM stereo signals from free space and sends the signals to the radio receiver for processing via a coaxial antenna cable. Good antenna grounding is important for good radio reception.

Radio

The operator interfaces with the radio system through the radio display and controls. Through these controls the operator is able to control system power, volume, fade, balance, bass, and treble equalizations. Control on the integrated CD, MP3, or XM Satellite Radio system is also available when equipped with these options. A VFD (vacuum florescent display) provides system feedback to the operator.

The radio processes the AM and FM signals from the antenna system or the information from the CD media, amplifies that information and sends the output to the speaker system.

The radio is located in the instrument panel center stack area and is fastened to the instrument panel by fasteners. A rear bullet type guide pin is provided to aid in aligning the radio. An electrical connection to the radio is a 30-way connector that is part of the I/P harness, antenna lead connector, and an additional 16-way harness connector is present on OnStar(R) equipped vehicles. Additional service length is provided in the radio harnesses to allow connection prior to radio installation.

Radio amplifier outputs to the speakers are protected from damage should speaker leads become shorted to ground or shorted to vehicle power. The radio will sense these conditions and shut down the amplifier outputs in a non-destructive manner. After the short condition is removed, the radio will return to normal operation.

Tomatosoup to the rescue once again!:)

Well I check out the bolded paragraph as instructed, not sure what it exactly means though, so it'll take some more studying before I completely understand it.

Sounds like you have a grasp on it though -In small words now if you don't mind, do you think we are going to find a cure for the front speakers not working by chasing it as an issue that could be fixed working with the amp triggers or amp at all? Or do you think we are looking at the wrong end of the dog here?

The reason for asking is that the speakers are not the only issue we have still to be addressed, we also have the steering wheel controls not working and while testing that issue we plugged in the boomerang only to find our hazard lights to be on permanently. We tested the switch and it past a continuity test for on and off function.

The problems might all be related in some way, but we figure our best shot is to work through them one at a time. Stereo was the most important, until it was up and running we didn't know we had other problems...

Thanks again for all the help, without this forum and members help -who knows how long it would be before this car was on the road again. We bought the car wrecked and I've yet to drive it - been working on it since the day it came off the trailer and it it looks cool with all the paint and such! Shame it's just a garage paper weight right now though!

DANGER WILL ROBINSON!!

If you're having issues like that with your hazards, then the wiring in your setup is wrong and messing with your BCM. STOP and disconnect everything first to isolate that wiring issue. You could blow your BCM and they are expensive to replace/reprogram!

Once that is solved, then make sure the remote line on your amp is grounded. Your mute issue sounds like (maybe) your remote line is floating and picking up noise that the amp is interpreting PWM signal - thus muting channels. Not guaranteeing this is the issue though :)

Well! In the time since we wrote we chased another issue with the airbag coil. We'd changed the steering wheel that was damaged, in the process of finding the flashers constantly on, we also found a broken turn signal assembly. Chasing it we then found the airbag coil had a part come loose inside the steering shaft.

Looks like the previous owner who'd wrecked the car had punched the airbag to the point of denting it. The impact not only dented the airbag but appears to have popped the cam (plastic ring that attaches to the rear of the coil), that turns off the turn signal.

We've replaced the turn signal assembly, took the airbag clock out reattached the loose ring / cam ring and re-clocked the air bag clock to make sure we were centered.

We totally agree we need to regroup and double check everything from here. It is feasible that the steering wheel switches might have been damaged by the previous owner. The airbag clock contains wiring for the switches as well.

Once we purchased the car we were able to drive it off the trailer and into the garage, but after that found several fuses out and blown. Hit on the right front, the hood had pinched wires up front, those were fixed while I was doing the bodywork, but who know if there is other unseen damage.

We'll fall back to putting the stock radio back in for the moment and troubleshoot everything before bringing the new head unit back into the car.

Just have to be sure everything works like it should before bringing in the new components after finding this airbag situation.

The car had 39 dents, some really stupid damage, (owner had tried to pry open rear hatch via breaking a taillight out instead of putting a new fuse in the hatch release).

The owner only had the car six weeks before wrecking it His mother's car bought new and handed down to him. Never met him, but it's obvious he was a true village idiot -get this -this owner was employed at a local GM dealer -guess his uniforms were locked in the trunk of the Solstice when the crowbar came into play...

Will report back!

Thanks again!

I just installed the pioneer 6700bs today and I used the GMOS -LAN-04 and everything worked except the steering wheel controls ( Crutchfield tech support says it does work in the sky and solstice and has to be hardwired). That's not a deal breaker because my hands are inches from the radio. It allows you to adjust the chime and the level going into the monsoon amp. Was there a reason you didn't use one of the pre-made wire harnesses?

Hi, we did purchase the modules:

Scosche kit #GM13SR, the Maestro SW control interface ADS-MSW, SiriusXM Tuner SXV300

Problems we ran into was there was no clear instructions with the Schosche or the Maiestro. The Schosche had wires in the harness that are not shown or covered in the wiring diagram, the Maestro instructions online just showed a drawing (a line), of a connection to the radio. We programmed it before hooking it to the car, have no clue if that should have been done after wiring it in. Near as we could tell we wired everything correctly, but the not being sure -issue is what prompted us to yell for help.

Initially we'd missed the blue/white trigger wire hookup and the one that was labeled ant. remote we thought was for a power antenna if used. That one we now think should have went to the Maiestro green and yellow -but again not sure.

Connecting the Maiestro, we've read not to soldier it, something about resistance -of course we used T-taps to connect and soldiered the spade connector, so if resistance is an issue, we have problems there.

All these issues and unknowns are the reason we think we should put it back to stock for the moment, just to be sure the basic car side of things are correct then add the modules as we go. Adding the head unit and the modules just added to the confusion, since we had problems like the clock spring we weren't aware of...

Thanks!

Quick follow up -with everything back to stock, with the 6 disk cd changer, everything works BUT the door speakers! Steering controls work, and there was no hazards flashing.

TomatoSoup was right, probably something we either don't have wired properly or other issue was the cause of the hazards being on. Although the repaired turn signal or airbag clock might have been involved...

Not a sound from the door speakers, no crackle, or any sign they even exist. Not sure where to begin to chase that issue. Amp appears to be working just fine, not sure if the amp has a separate channel for the door speakers that might be out or blown or if the speakers have an issue.

Although while the aftermarket head unit was still in we did use a rca cable to run to a known good 4 ohm speaker and got nothing from that test. No sound, so that might help in finding why the amp isn't working to power the door speakers.

Anyone know if the amp might be the issue? If so we can go ahead and start putting the head unit back and assembling the dash one module at a time to look for a bad or incorrect wire connection

Hope someone has thoughts on this!!!!

Thanks
