adding a sub to bose stereo

[PeanutGallery]

any tips on adding an aftermarket sub to the factory bose 9-speaker stereo? the stock sub in the center console is rather weak, particularly within the cavernous volume of the suburban body (!), so i'm thinking about adding an aftermarket sub & amp if i can find a relatively painless way of tapping into the stock system and not impact the operation of any of the other interconnected systems.

having run into integration issues while adding a sub to a bose system in a previous car, though, i'm wondering just how difficult it may be on the GMT900's. any input? are there any wiring harnesses out there that make this fairly easy, or is it a trial-and-error process? i'm by no means a car audio pro, and i'd rather not hack into the wiring only to end up with interference and functionality issues....but having a bit more bass sure would be nice! i have an older amp & 10" sub lying around in my garage gathering dust (nothing special - phoenix gold XS2300 amp, MTX 5000 sub, non-ported ~1 cf box) that i'd love to drop in there if i can find an easy way to do it. one 10 may not even do that much in something this big - it was originally in an acura RSX-S hatchback - but i figure it's a start....

thanks

There is a black box that talks to the GM Lan data bus to get the signal you need like this one:

I'm sure there is at least 2 or 3 more vendors that have a box like this one.

In my 07, I'm using a Xtant sub amp that takes hi level inputs so I didn't need the box above. I removed the center console sub and have two amps in there and had a custom box built in the back.

That is awesome! I was looking for exactly that part a few weeks ago and came up with zip. Thanks Snomon!

This is exactly what I used then ran the wires to the amp which is attached to the Sub box at the back of the truck...MUCH better :thumbsup:

Hey, this is great news! BUT... Does anybody have any suggestions as to where to inconspicuously place a new subwoofer in the 07 Hoe w/o compromising space? I have 3 boys and I don't want to give up any unnecessary "loading" space for a sub encasement... Pics would be great!!!

If you have the front center console you can add the JL Audio Stealthbox. It is kinda pricey though...

Thanks, Gambler! You weren't kidding about it being expensive!

Do you think it replaces the OEM sub or supplement it?

My understanding is that the OEM sub is in the same location, so it would have to replace it. I don't have the Bose system so I can't say for sure.

The Bose system in the Tahoe is not on the GM Lan. The head unit could have a GM Lan connection in addition to the outputs to the Bose system, but I'm not sure. As it is, the amp gets all of its instructions from the head unit on individual line level channels.
