What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[08z71bgm]

Have any of you put subs in while leaving the stock head unit and door speakers? I know its the less preferred way to do it- but i kind of want to pull the subs out of my old truck and put them in the back. I know you need a LOC to do this- what one and where does it need to go to do this?

I did it in my Holden with the factory Bose stereo still intact. Used a lc2i signal processor and tapped off a speaker signal wire. In my case I have factory subs also but very weak so I tapped off one of them.

Works great.

The problem with tapping into the speaker wires with a LOC is that a lot of the bass has already been filtered out by the Bose amp to go to the factory Bose sub. If the LOC can handle the wattage, tapping into the signal to the Bose sub may produce satisfactory results. The problems there are (1) it's a DVC sub and (2) it's a small sub so it's crossover has been programmed accordingly and this may leave some to be desired with a larger sub system.

I've found pictures and wiring diagrams before, but you can tap into the low-level, full-range signal going to the Bose amp with some RCAs (cut the RCAs and solder them in) and run RCAs to your sub amp as normal.

Goin through something, took a quick trip to Canada to blow off some steam:

It hasn't blown up yet!

Or you can tap the amp inlets instead of the out. Pre digital processing. Then no worries about lost signal.


Also you should read how the lc2i works. I used it in two cars one with Bose and one without with factory radios with excellent results.

Don’t think I installed this right... it seems to stick out too much. Thoughts?

Looks cool to me.

That definitely helps blow some steam.

I did that once in middle of no where in Canada and passed a cop going the other way, but all he did was flash his lights and kept going.

Took apart the calipers and painted them red tonight (I’ve heard people gain 5-10hp, so thought I’d try. )

Goodness your exhaust sounds good!

if you have the bose system then likely the bass signal is filtered by the bose amp so you would need to tap the stock bass speaker output with a hi/lo adapter, if you used say a door speaker output you may not get any bass signal out of it.
