Ripping Out 01 Suburban Delco Set Up

01Burb · May 18, 2003

I have an 01 LT Burb. From what I can see, I have a tweeter and a 6.25" full range in each front door, a 6.5" full range in each rear door, a funky 1.5" tweeter looking thing in each rear pillar - one either side of the rear doors and a 'subwoofer' in the drivers side rear panel. I have a Delco Theftlock radio/CD with the remote casette.

How are these speakers wired? Somewhere I read that the rear 'tweeters' are wired in series and get a mono signal.

Anyhoo..I have some amps and a crossover, I plan to replace all the speakers and was wondering the best set up. I really need to know how the rear sub is configured. Is there a sub output on the head unit and if not, does it get front or rear or both signals, does it have a crossover and how are the 'tweeters' wired.

Thanks

If you are getting rid of all the factory speakers...I don't think it really matters how they are/were wired.

Also, if you are amping them, you can decide which channel to run the sub off of. I'm not sure (mine didn't come with a sub) as to whether or not the Delco has a sub output. Somehow, I doubt it. I ran my subs off of the rear channels.

If you replace the Mids/highs with seperates -the best way to go in my opinion- they will come with a seperate crossover and instructions on how to wire them up.

Go to: Install doctor It's an Adobe file that lists the colors for polarity on the speaker wires as well as the rest of the harness wires off of the back of the Delco. The rest of the site is pretty darn useful too.

Hope this helps

Good site. Thanks. I still need to know how the sub and the rears are wired though so that I can figure out what wire if any I will need to install.

You will have to add line output converters. Unless your amp will take the speaker wires directly.

It only takes about 2 minutes to pull the stereo out and check the wiring.

Only thing is...I have the Delco Theftloc w/seperate cassette too, and when I pulled the stereo out, the harness for the tape deck isn't long enough to pull out with it. You have to reach under there, and disconnect it (not easy). Putting it back in is a real PITA too.

As for how the sub is wired, I would assume that it is just run off of the rear channels, and there is some version of a crossover back there with it.

But if you are keeping the head unit, and your amp doesn't take speaker wires directly, you will have to use the line output converters. In which case, you will have to decide where you want the signal to come from. How the factory did it is not really a factor.

You will need a lot of wire for that Suburban no matter what. If you are adding your own amp to a new (better) sub, the factory wiring should be the first to go anyway....and you have to run the wires from the head unit to the amp, or amps...Then allllll the way back to all the speakers. It's great fun. Get some beer.

I'm probably going to get the Pioneer 1.5 DIN unit up front although I'm looking for a 1.5 DIN unit with XM or Sirius satellite capability. I'd like to put a couple of amps behind the rear panel where the woofer is. I started a thread in the Light Duty forum asking what is behind the rear panels since they sound hollow.

I figure I will find some small speakers to go in the rear panels and wire them as a second rear set and maybe cross them over with the woofer since they are going to have to be small anyway.

If I can't find a reasonably priced 1.5DIN HU with XM i will get the small pioneer XM unit and see if I can make it work in the factory cassette location. If someone made a conversion for that, they would sell a lot of them.

This Pioneer will run an XM receiver (the Pioneer one, of course) and will fit perfectly into your dash. Keep in mind though, you don't have to have a 1.5 DIN. The regular ones will fit with an $8 kit. You just have some extra plastic around it.

The Pioneer stereo above also has 3 sets of pre-amp outputs, so you will not have to "split" your signal to different speakers, let the stereo do it for you. You also will not have to use the line output converters that I was talking about earlier.

I have no idea what is behind those panels though. My 92 has 0 room behind those panels, but it's a little different. I mounted a small amp in the dash behind the glove box, and one under each seat. My 02 Ex cabs seat motors are too big to do that now...Yours probably are as well.

Hmm, I think Crutchfeild have that wrong. That is the exact unit I have been looking at and it is the first time that I have seen it described as XM ready. For starters, it does not carry the XM logo, the online manual makes no mention of XM, it is basically a 4 year old design - way before XM and Pioneer's site does not mention XM.

I noticed that someone just installed one of these on this site and he says no XM so I think I will call Crutchfield and ask them.

As much as I'd like a 1.5 DIN, that Pioneer hasn't been updated in like 5 years. It just looks kind of dated, and doesn't have the latest features.

Alpine used to make 1.5's, but seem to have exited the market. I guess there's no market for them.

Spoke to Crutchfield. The unit will accept an XM satellite through the IPBus using the Pioneer XM tuner. If you have a CD Changer, you can then plug the changer into the XM unit in a daisy chain. You can control the XM unit but you may not get all of the display - my guess is it won't scroll probably.

I think I am definitely going to do this.
