Chipping away on my new install

The last couple of weeks I have built, carpeted and installed my sub in the extended cab of my Colorado. I mounted it between the jump seats requiring me to relocate my jack. Also, I removed the storage boxes from under those jump seat and made a place for the amps.

I have had FedX and UPS deliveries of my Alpine CDA-117, Imprint along with the calibration mic along with Madisound woofers and tweeters (nice). I spoke with Don at Sound Deadener Showdown and he sent me my MLV, tiles, glue and roller. I will be deadening the doors only for now since I'm going to be in there replacing the speakers. Instead of the CCF for the deadener I will be using jute, the CCF makes me ill.

I still have quite a job ahead of me but I have amassed quite a bit of stuff to prepare myself and try to put forth my plan of attack. I am still waiting for the leather shears to cut the jute with but I have other things I could work on while waiting for the USPS to get them here.

I do have a concern though, I want to feel reasonably secure that I won't accidentally set off the air bags. The airbag control unit is hooked to the same panel I need to remove to get the HU out and I did read from the Crutchfield Master Sheets that this is a possibility. I am hopeful there will be enough length of the wire harness cable to just sit that cover on top of the dash so I don't have to unplug it. I do know that I need to unhook the negative battery terminal first. I read somewhere that I should wait at least a half an hour after unhooking the battery before I pull the panel.

Any thoughts? Bryan

once you unhook the battery there should be no issue but some cars it is good to wait.And I want to say it is a good idea to install the sound deadener first. I put my system in and tuned it then installed the deadener(spelling? max ice is the ish!) and had to re-tune(comp set tuned to abt 80hz instead of 100hz appx.), but its ok it keeps me out of the house! Also I have the 117 but am running passives until i get more money for something louder, but i want to run active eventually, so ill keep posted and good luck I love my 117!

I will be deadening the rest of the cab eventually but I have put in quite a bit of money so far so I'll have to wait a bit. At least I am getting started and I do have the calibration unit for when I do finish the deadening. I am glad to read you love your 117.

Keep us posted with your progress Bryan. I can't be any help with the airbag issue though. Sic might have experience with it. You gotta take pics of the goodies and post them.

Larry, how and where do I post pictures? I would like to post a few pictures as I go along. Maybe I had better look around the site a little better.

to post pics embedded in threads, you have to use the html code.. This site does not support php coding, so using the [img] [/img] tags won't work. You can also post links to images instead of embedding them

Be absolutely sure about your airbags before you mess with anything. There is usually a forum for every model of car out there so go around and ask. A lot of 2000 and later cars have caps in line with the bags so unhooking the battery won't do any good until like 5 minutes later. Thats how it is with my pt cruiser.

Your air bags will not deploy no matter what you do. (unless you hook them directly to a power supply) Worst case scenario is your air bag light will turn on and you'll need a diagnostic comp to reset the system. As for waiting 1/2 an hour.... its a crock. Never done it never will, no ones going to pay me to sit around. Turn your lights on to drain any " residual charge ". Double check all your connections before you reconnect the battery.

Obviously you have never removed a steering wheel. And its not a crock if you know how they work lol. The airbags caps would not be on the same circuit as the headlights. That kinda defeats the purpose.

I will follow-up on picture issue later.

On the airbag I am going to do some checking, I did leave a question on a Chevrolet Colorado forum to see what comes back, and I'll try contacting the dealer and ask them.

to drain the system entirely ( static can deploy the airbag!!! ) disconnect neg then positive then holt the 2 wires together for 5 minutes... that is the accepted ASE way to do it on all cars. and it is required to guarantee that static or errant system voltage does not trigger the bag..... I have seen what happens to people that have them go off in their hands...not pretty..

Sic,

Making sure I get what you are saying, disconnect - terminal and short it to + terminal to drain for five minutes. I could just use a jumper cable and leave it on there the whole time I'm working in there. Great, that's easy! I did post a question on the 355nation (Chevrolet Colorado forum) asking them but I haven't checked for replies yet.

Thanks to all of you.

I stayed up late last night soldering my Axxcess GMOS-01 to the Alpine harness. I probably won't do any more this weekend and start fresh Monday. I need to get new speaker wires through the door, not looking forward to that.

disconnect BOTH POS and NEG terminals completely from the battery, then jumper them...
