Hi all. I just picked up a 2004 Denali about a week ago and it's really hurting for some bass. In my last Chevy, I just swapped everything out and did a custom system. I want to do the same with my Denali, but I really want to keep me stock HU. Can this be done?

I have the Navigation HU, with XM, and RSE and would like to keep the steering control options as well.

Does PAC make a unit for this? If so, can anyone help me ouot as to which unit I need?

 

Thanks

I did a little research and found out that I won't be able to get a 4 channel amp to power up door speakers and another to power up my sub without changing my stock HU. PAC told me that the best thing for me to do was buy this PART and I can get thru JP Customs.

I guess I will go that route.

I'll let you know how it works out for me.

My wife has a new 2004 Yukon with the Bose/XM stereo, and I too think it sucks. It has the sub in the console (I assume yours does too) and it is pretty weak. Turning up the bass on the head unit helps some, but it still seems sub-par to me. If it were mine, I think I would consider the JL Audio Stealthbox. Have you seen them?

You most certainly can add amps to the door speakers, and a sub...Unless you have Bose. Then it gets really tricky.

 

If you don't have Bose, (unless there is something really funny about the NAV unit, and the way it distributes power) you should be able to just throw a couple of LOCs in there ($20 apiece) and be golden.

I'm using one of the C2A-GM24 in my Sierra Denali for my subs. Does a decent job. I've had one problem that I'm trying to fix right now. Occasionally, the factory amp doesn't turn on. All I have to do to get it to start up is turn volume on factory stereo up or down and the amp starts up and sound comes out of my speakers. I've got a new C2A-GM24 on it's way to see if this will fix the problem. To complicate matters I'm also using another PAC adapter for auxilary input (AAI-GM12). When I talked to PAC about my problem they said that the aux input wouldn't cause it so it was probably th C2A-GM24.

So your AUX is for your DVD/TV...ect., correct?

Cause I was thinking of doing the same thing. I just wasn't sure if it was possible to connect the both. My next option was just to hook up a set of wireless headphones for sound on the DVD player.

I am looking to add an amp or 2 to my factory radio in my '04 GMC Sierra. Do they make a plug and play LOC? I don't have a Bose system just the standard cd/casette player. Will the C2A-GM24 work for me or do I need another adapter? :thumbs: Thanks

You can bypass the stock amp with out replacing the HU by following the wiring harnness back and you will run into a connection take that off and run it to the back of the HU my require you to buy an extra connection form local dealar but it will work i have done it before. Also anyone no of a few places that sell OEM navigation units?

The "Premium" Boze systems doesn't help their reputation at all. Denali's and Escalades have Luxury systems that have more bass but little change in treble (unless you add pocket tweeters) but far cleaner sound. It won't win dB drags or blow out windows a block away though.

I just sent a PM about this, but do any of you have experience with using both the PAC-Audio AAI-GM12 aux input adapter AND the C2A-GM24 OEM amp adapter TOGETHER with an 04 Denali (or similar setup?) I got everything factory (nav, XM, cd changer) except the DVD system, which I installed aftermarket and want to connect to the factory Nav HU.

 

I'd like to add a JL Audio 500/1 amp and then put a JL 10w7v2 sub in the rear empty space where older subs went. Then I would have clean audio from my DVD (via aux adapter) with solid bass from JL and factory Bose sub (with amp adatper).

 

I also don't want to lose any functions...like having to disconnect my CD changer or disabling XM. There's got to be a way...

so yeah...they say that it works with the "Luxury" Radio, but does it work with the standard GMC Bose systems?? has anyone used this with a GMC Sierra w/ Bose system?? just curious as i'm picking up my truck on sat hopefully, and i'm gonna start building the box for a sub here in the next couple of days.

 

thanks,

very easy just get the line output converters which turns your speaker wires into rca's then atach patch cables to the amp and there ya go. thats what im doing in a few weeks to ad a sub to my stock cd player

I am putting in JL tweeters in place of the blows tweeters in the pillars , should I use the high pass filter that comes with the JL's or leave them off? I have the non-lux premium blows amp.

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.

      I always drive in Sport mode. With more driving, I am finding the initial response when accelerating is much quicker now🖕 Lou

      Is it an optical illusion in the pic or is the truck really squatting that much horribly?
