Did you change your speakers? I thought I read somewhere that the OEM speakers are different ohm than what aftermarket head units can run. Maybe that’s just Bose systems though…
You would have to buy some sort of adapter because the head unit does not have 8 wires (4 speakers, each with a + and -) coming out of it. Cadillac did not make it easy for radio swaps
@@TheGarageDocI already have an aftermarket system installed. 2 Ct sounds strato 12’s on a recoil 2500.1. I think the factory amp is the reason for the humming coming from my subs.
theres a way easier way i’ve been searching for weeks on how to install a double din in 03-07 cts, its a PAC wiring harness and it makes it plug play with any head unit, its on amazon the name of it is “ PAC Onstar Interface for 03-07 CTS & 04-07 SRX “ has no rear speaker connections tho so i just tap those into the front ones like front left + and rear left plus from your aftermarket head unit harness go with front left plus on the harness for the car and so on and so forth
So are you just not able to use the factory amp when you install an aftermarket radio? I need some explanation I’m just confused why you can’t tap into the connector coming off the back of the radio
Yeah it’s a bit confusing. When you put a new double din radio in, it comes with a wiring harness, because not every vehicle has the same connector. So the normal 8 wires ( 4 speakers each a + and -) that you connect the new radio to are usually the back of the radio because they usually have an amp inside them. But if you skip to 3:01 on this video, you’ll see that those 8 wires are actually in the trunk instead. And from the trunk, they run wires to the speakers. So the route I chose was to take 8 wires and run them from the new radio up front, and then go to each speaker from there. I hope that helps explain it some
Those wires in trunk are the output wires for sure? I don’t wanna tap into them and be the wrong ones…. What wires are for the tweeters and center speaker? I wanna tie those into door speakers
Yeah all the colors coming out of the amp on the big connectors are to each speaker. I can’t tell you for sure the colors but if you check the wiring diagram it’ll say something along the lines of “rear center speaker (+ white/green) ( - red/black)
pinoutguide.com/Car-Stereo-GMC-Opel-Chevrolet/Cadillac_2002-2008_CTS_BO_pinout.shtml here’s all the outputs. Definitely easier to understand with the pin labels instead of just using the colors
This car (and possibly all Cadillacs) is very different from any other one I’ve dealt with. I’ve always been able to use a wiring harness to put on a new double din, but I could not find one that was even made for this car. This car also uses more than just one or two factory harnesses (as seen in the video) so I think that is what makes it difficult to adapt to a typical double din radio which just has one or two connectors

I used my stock speakers and didn’t notice a difference
Where did you get that dash kit? I can’t find one . Did you order it on line?
I ordered mine on Amazon. Just typed in “2007 Cadillac double din dash kit” and it was on there
Hey bub, what color is what, when u take out the factory radio,I don't have no wire harness..
The easiest way to check is to look up the wiring diagram. A Cadillac forum should have it, that’s where I found what colors mine were
@@TheGarageDoc ok cool,well I finally fixed it about a week ago,but thanks for responding back bub.
So what would happen if you remove the factory amp?

@@guestguestthat would usually be from a loose ground or loose RCA connections

I cant just use a wiring kit to connect behind the dash? Like some other cars.

So there is no wiring harness for a 2004 cadallac CTS?
@@paulherdon1678I searched everywhere and couldn’t find any for the 07, and I believe the radio is the same for 2003-2007
That's I love like that eat explanation and fast
Goodluck!
I have a 2006 cts and mine is so different
Is the head unit a completely different shape?
