Chevy Tahoe Install Questions

[latemodelsedan]

I know this is gonna be a helluva introductory first post but I really need to get some advice hopefully from some professionals and other enthusiasts. I’m gonna try to provide all the necessary info in my initial post so bear with me if it’s long winded or if I leave anything out. To start, I’m doing a very, very modest upgrade and have no desire to shake the pavement. Those days are over for me. So, I’ll start with my vehicle particulars and then current equipment.

Vehicle:

2010 Chevy Tahoe LT

w/BOSE

w/OnStar

w/o Navigation

Current Equipment:

Pioneer AVH-P4300DVD

Rockford Fosgate Punch 500-4

Boston Acoustics S60 Components – 2 pairs

Axxess GMOS-LAN-02

Avital 5300 2-Way Security

Okay, so here we go. I’ve already removed the OEM head unit and all the Bose components except for the “sub” located underneath my center console. I have replaced all of the full range drivers with my Bostons and installed the Punch amplifier to drive them. My installer left the Bose sub fully functional at my request to determine if I would be satisfied with the sound before deciding to keep moving ahead. I guess this was silly because although I knew it was gonna sound bad, it actually sounds a lot worse than I expected. So, here are my questions/concerns:

1. My installer told me that after removing all the Bose components he had to install a small speaker behind the center console in order for me to hear my door chimes, OnStar, turn signals, etc. I thought that was the purpose of the Axxess GMOS-LAN-02. Isn’t that module supposed to allow everything to continue to be heard thru my stereo speakers or would the disconnection of the Bose amp from those speakers necessitate the installation of a new external speaker?

2. Should I be hearing a small amount of “noise” when I pause music/dvds etc. or should there be dead silence? When I say noise it’s not alternator whine or anything like that, it’s more of a very small amount of feedback I guess as a result of amplification. Just not sure if or how much of it I should be hearing.

3. When they installed the Avital 5300 they connected the tach wire from the alarm to a solenoid in the engine compartment and it TOTALLY drove my computer haywire. The car went bananas. The Stabilitrack and check engine lights went absolutely bananas. After much troubleshooting they finally determined that wire was the cause and eliminated it all together stating I didn’t need it. Can anyone advise on this? The alarm functions perfectly without the wire and the vehicle now runs as it did before.. perfect.

4. I need help choosing an inexpensive but quality pre-fab subwoofer enclosure. I’ve already decided to stay with Rockford for the sub amp. I’m leaning towards a Punch 300-1. As I said, I don’t wanna shake the pavement or draw a lot of attention to myself. I’d like to get a simple sealed enclosure with two 10’s. I found a few places online selling the discontinued JL Audio CS210-WX enclosure very cheap and I’m certain I don’t need much more than that but I am open to suggestions within my budget.

I think I covered everything. I know it’s a lot but I figured it was best to get it all out at once. Thanks in advance and i look forward to participating in the forums.

im not professional or anything.. but i recommend doing everything yourself.. much better results and you get to learn what you have rather than get someone to do it!

first thing i would do is get a detailed list of what was done, and what was charged for...... with all the databuss in there, and still partially installed (has to be to run the factory sub without installing an amp for that sub) i would not really suggest picking that, or a honda as your first go-around. the fact that they installed a relay and failed really shows that they may not know what they are doing at all....

agreed ,does sound like they dont know whats going on here.the chime usually does come thru one of the speakers in the system,so just need to figure out which one ,most of the time id easy tho.never heard of an alarm making the ecu going crazy ,so they had to of had it hooked up to the wrong place [which is my bet] or did something wrong in the wiring.also if done right,shouldn't have any noises of any kind when turned down.and last but not least look at obcon and q logic if you want a prefab box

Waaaay too much to read, but my daily is a newer Tahoe, so you can PM me with any question and I can probably help.

The door chime is like a small speaker in the dash or console depending on the year. My Onstar speaker is located on the side of the FRONT rear a/c control/click lights between that and the driver visor.

also, if you look in the manual, or youtube there is a light/ seatbelt combo to turn it off. 99% sure i have done it in multiple veicals.

yah....that's exactly where my onstar microphone is located..... about the size of a quarter, iirc.... the sound is played through the speakers. i did not take the liberty of looking up your models, so i'm not sure, but it does sound like the head is either capable of playing the features through the speakers via the lan unit, or that the lan unit is the interface module for any aftermarket head, which has it's own speaker...... i kept my factory head installed, because i like the nice quality sound of the chime and onstar, rather than a cheezy speaker hidden in the dash..... reminds me that it's still an american vehicle, not a chinabox from the 90's. both where they hooked the tach wire, and likely using a shield wire as the ground is what would show how they are not familiar with databus wiring. honestly, they could've tapped into a coil wire and set the ppm to match the firing of that cylinder, unless the ppm programming can support a crank/cam position counting, etc, but really i would concentrate on getting the info on what was all done and check things out before deciding what to do....

this is actually a reputable shop thats been in business for about 20 years here and to be quite honest i've totally lost faith in them. the installer seemed to have one answer for most of my questions .. "i don't know". but once they've done the work it's kind of difficult to get detailed info.

i will say this, the alarm works fine. aside from that hiccup with the tach wire there are no issues. re: onstar and my chimes, i definitely want to keep my onstar and prior to changing out my speakers yes, the gmos lan DID play the chimes thru my left front speakers. the installer stated that removing the bose drivers and cutting the leads from the bose amp to those drivers made adding the external speaker necessary. the other thing i have to admit is that i actually spoke to several shops before getting the install done and it seemed like none of them had concrete answers for issues re: swapping my bose crap out and retaining my onstar. seemed to be a gray area for all of them to a degree. very frustrating.
