Complete writeup w/pics on removing Bose system and installing a Pioneer AVIC D2
w/aftermarket speakers and amp in a 2005 C6 w/OnStar
This is a write-up on how I totally removed the bose system, amp, speakers, HU, everything, and installed a Pioneer AVIC D2
and Pioneer GEX-P920XM
XM receiver with Image Dynamics CSX62
, 6.5" separate system in the doors and two 10" subs in the rear in a custom built fiberglass enclosure and amprack all running off a Fosgate P850.4
Ok, I won't bore you with the little things that you already know, like how to remove the console trim or door panels and such since there are a dozen threads on them and I know you will just scroll past it anyway. Therefore, I will start with the doors….
I removed the 10" woofer-like-things and traced the shape of it out on 1/2" MDF. I then traced the 6.5" mounting hole in the center and commenced to cuttin' like a ****. I then painted the baffles black, mounted the 6.5" mid and attached it to the door.
I did the same thing for the twiddler thingy-ma-bobs in the door panels. Again using 1/2" MDF I traced the shape of the twiddler and the mounting hole for the new ID tweeter, painted them black and mounted them back onto the door panel.
I ran 14-gauge speaker wire for the mids and 16-gauge speaker wire for the tweets from the front to the back of the car. For the driver side door speakers I ran the speaker wire, along with the RCA cables, down the driver side sill area. For the passenger side door I ran the speaker wire under the dash and down the console tunnel to the rear since I used the passenger side sill area to run the 4-gauge power and ground wires for the amp. I separated the speaker wire and power wire runs because it isn't good mojo to run signal wires and power wires in the same path since it can introduce noise into the system.
That's my story anyway and I'm sticking to it.
In order to run wire into the doors you have to remove a black plastic cover. Behind it is a nice large cavity to run your wires through the rubber boot to the inside of the door.
I used a "step bit" and drilled a 1/2" hole in it, put a rubber grommet on it and ran my speaker wires through it into the door. It is really quite simple to do. I didn't get a picture of this but since this is a living document I will try to remember to get one some day if I happen to pull the sill trim panels off again.
I removed the stock Delco 6-disk in-dash CD changer HU with XM that went with the Blose system and replaced it with the Pioneer AVIC D2 DVD/NAV setup.
I needed a mounting kit to install the AVIC D2. It is the double-din Metra kit #95-3304.
You can pick one up here:
Since I removed the Bose amp and all, I need to use this data bus module from Peripheral. It is model #GMAH24
. This unit retains my OnStar system as well as keep the cars ECM from thinking any shenanigans are going on…like…installing some rowdy aftermarket stereo system or some such nonsense.
It looks like this and you can get one at the same places I linked to the mounting kit.
Oh, and I needed one of these little buggers too! It is the GMAHCM
also made by Peripheral and it keeps the cars interior "chimes"….chiming. Without it I wouldn't know if I had my seatbelt on or not.
Again, you can get one at the same places I linked to the mounting kit.
And now for something completely different.
Ok, now remember when I said I removed the Bose system…completely? And because of that I need that doohickey to retain my OnStar? Well, I also need to run some speaker wire to a separate speaker to hear the OnStar "voices" and phone through since I no longer have a Bose amp and speakers to do this for me, and even though the voices in my head provide far better conversations, they can't replace the OnStar voices. So….what to do? Well, there are some wire outputs on that GMAH24 whatchadinkle that are meant to go to speakers. So what I did was I removed the center channel from the dash.
I then unplugged the Bose connector and soldered the positive and negative speaker leads to the terminals on the crappy Bose paper speaker. I figured, why not? It will only be playing a voice through it so it doesn't have to be a great speaker. Besides, there is no such thing as a "stereo" voice, so mono will be just fine.
I then ran the speaker wire through the dash and hooked it to the speaker output on the GMAH24 dojigger and VOILA! I now have OnStar through the center dash speaker! This is how it looks.
Now, since I removed the stock Bose system the factory XM receiver is useless. So I installed the Pioneer GEX-P920XM
XM receiver in the empty well that was left behind when I removed the Bose amp. It's the perfect spot for this gizmo.
I then ran the wires and new XM antenna up to the new HU and mounted the XM antenna next to the AVIC D2's GPS antenna on top of the vent ducts. Seems to work just fine too! Both the GPS and XM antennas are each about the size of a quarter so they fit perfectly on the vent. Also the antenna wires are run in separate directions to avoid interference.
Here are a couple pics of it.
I need to run grab a drink sooooo…watch teh funny till I get back
