Sounds like a solution for those who want a simplified way to upgrade.
    Pat, Can you find out more info PLEASE? Is this specifically for the CTS/SRX, as this is the only vehicle I have ever encountered where there was only two channels going into the amp and the amp controlled fading.......Who is this someone???

    I will certainly find out what I can, but I was told that it wasn't Pac or Soundgate, he wasn't very eager to give out any details, guess it's a control thing for these guys. ( pfft ) I've got an appointment tomorrow with Benchmark Audio, I'll ask them, they have 1 or 2 installers that are are rated pretty high nationally, so if anyone knows, I'm sure they will. I'll certainly find out what I can and report back.

    Metra I know is working on an unit so you can replace the headunit and retain onstar and such, but I was unaware of a part for replacing the amp...

    But, I have figured out how I am going to do it...I'm going to work out the details this week, and post prelims on my site this weekend or earlier...

    Re: After Market High End Audio Options?

    Well, here's where I am. I had one idea, which is more complex...And then I had another idea. My "new" idea would really only work on the Non-Bose, unless you want to get rid of your DSP.

    The non-bose system has 8 channels coming from the amp:

    Front Channels:
    2 channels (L&R) to the tweeter with a highpass probably in the 6-7kHz range.
    2 channels (L&R) to the front door with a lowpass probably in the 6-7kHz range.

    Rear Channels:
    2 channels (L&R) to the rear doors full range.
    2 channels (going to both voice coils) to the sun, lowpassed probably in the 400Hz or less range.

    Now, when you write this out like this, something clicks...

    Why not combine the front channels back together again to make a full range signal - I mean, the amp is pulling the signal apart, why not put it back together?

    So here's what I am going to do. I'm going to get an OEM-2 from Pac (the one with a built in amp turnon), and wire the left tweeter and left door back together into one front channel on the OEM-2, and then the right tweeter and right door the same.

    Re: Bose system

    The Bose system should not be tampered with. It's designed as a 5.1 channel surround sound that is engineered for the specific acoustics of the car. It's not a bass thumping machine, it is more in line with a premium home theater system and as such concentrates on quality, not quantity.

    A link that explains what goes on in the Bose system:
    http://www.bose.com/controller;jsess...ions/index.jsp

    FAQ on modifications from Bose's automotive website:

    6.Can I change my Bose sound system?

    a. Can I add a CD player or changer?
    Yes, in most cases. When Bose works with a car company to design a sound system, we almost always include provisions for adding CD capability. To learn which CD players or changers will work best, contact your vehicle dealer. If you're not sure whether your car has the option of adding a CD player or changer, contact automotive for more information.

    b. Can I add a new radio?
    No. Each Bose automotive sound system is completely integrated, with the elements custom-engineered to work together as a whole. That's why the music sounds so rich and lifelike. To help achieve this sound quality, special circuits are built into the system, including the radio. If you install a new radio, you lose these circuits. This can result in decreased sound quality, incorrect bass and treble balance, distortion at high volumes, loss of bass at low volumes and in some cases, no audio output at all. In addition, changing the display, which is also known as a headunit, will void the warranty on your Bose sound system.

    c. Can I add a subwoofer?
    No. As noted above, each Bose automotive sound system is completely integrated, with the elements custom-engineered to work together as a whole. If you add a subwoofer to the system, its output is unlikely to be proportionate with that of speakers already in place. In most cases, adding a subwoofer will detract from—not enhance—the sound quality.

    Essato!
    Even when it is possible to modify this systems, 99% of the times I strongly suggest to either keep the original as it is, or replace the entire system. I don't think is worth it to make a combo.

    Re: After Market High End Audio Options?

    Strangletooth,

    When you added the alpine amps, where exactly in the firewall did you run the power wire through. I'm going to be installing my Escort SRX when my V gets here and I need to know if there's a factory grommet I can run the front laser and radar sensor wires through. Thanks.

    Well.....(this is not directed at you, so forgive my tone that will follow) I have to WHOLEHEARTLY disagree. BOSE is full of SHisiTe and always has been, ESPECIALLY when it comes to GM vehicles. Did you know that BOSE hardly ever makes their own components??? Most BOSE systems are combinations of systems designed by OTHER companies, usually clarion headunits. BOSE is overpriced, and in MOST cases (GM), is worthless in vehicles. They CLAIM to test the vehicles, but I have talked to many a GM and Nissan engineer who said that BOSE never even touched the car. What normally happens is that the manufacturer (like GM) designs the placements and in some cases the components, and then runs it by BOSE for their "approval".

    In fact, BOSE is notorious for driving their amps hard to get good volume and SPL, but with poor distortion. Many BOSE amps are driven to 2ohms or even 1 ohm, causing huge amounts of distortion.

    I personally can say that the BOSE system in the CTS sucks. Absolutely sucks. I have put front kenwood components and a rear kenwood midrange in my non-bose, nothing else, and it has more volume and sounds MUCH better than the factory Bose system.

    If you frequent alot of import BB's, you'll find the common concensus is that BOSE sucks. This is because, in general, import buyers are provided vehicles with different variations of audio systems, like Harmon-Kardon, Mark Levinson, ELS, etc., and these systems rock, and in most cases cost less than the BOSE system in the CTS...

    This is evident in the "BOSE" speakers I have still in my garage that I have replaced over the years that are *paper* cones, *foam* surrounds, etc, and in some cases are *dual cone* speakers. Cost for BOSE on these speakers is probably $1.28 each. Companies like Inifinity, Kicker, Pioneer, Alpine, etc, don't even make speakers this cheap.

    It's really rediculous. Ultimately, BOSE has marketed their product so well, and made sure it was in the right vehicles, to the point that everyone thinks it's a good system. And most people buying GM vehicles who are familiar with *standard* GM systems, loves the BOSE...

    Sorry, audio systems, and the BOSE hype are just a sore spot for me.

    You think the BOSE system should not be touched, and I think the BOSE system HAS GOT TO GO. That's just our differing opinions in audio quality, and that's fine.

    To the left of where the steering column goes through the firewall (driver's side), there is a main IP harness line and huge grommet. Use that.

    Re: Bose system

    I didn't think my Boss sounds bad (truly, maybe my hearing isn't that fine tuned). Would I have been a lot better off (both cost and sound wise) if I only got a stock system and upgraded with an aftermarket system? I know there are a lot of louder systems (I hear them at stop lights, and sometimes louder than my radio); are those hign end systems?

    not really, all depends what they dump into the car. I can make a car load but it will sound like SH!T for around $400. It all depends what you want to do. The last system i did up for a friend cost him about 1500 and it was clear and loud and we had to dynomat the trunk b/c of the rattle. I did another one for about 3000 and it didn't get that loud but it was very crisp sound.

    Does anybody know if anybody makes a dash kit for installing aftermarket radios in the CTS? I did a quick search but didn't find one.

    Probably nothing out yet since there is nothing out yet to allow you to put a different head unit in. The headunit in the CTS does more than most vehicles - controls all the personalization, central locking settings, etc. All that is controlled by the radio interface. I don't think replacing the headunit is a good idea...

    Does anybody have any updates on this subject? I'm especially interested in the aftermarket adapters for bypassing the Bose amp.
