2022 RST TAHOE missing Bose Subwoofer?

BigRedRST said:

Where can I access the line out ports to connect a sub in the rear? Can I leave the factory center console sub connected and add an additional sub in the back? Or do I need to disconnect it? I haven't seen any good videos or guides on where people are running the cables

Like many of you, when I get a new car/truck I am compelled to do something to it. So I researched this forum and found all the threads on upgrading the Bose Audio system. Some people found the factory Bose system to be lacking at the subwoofer level. I found the bass to be marginal, not bad on...

All information you need to install sub in stock rear quarter panel is in above link. I recently did sub install in my Tahoe HC using above the info. No need to disconnect center console sub. You will need sub box, subwoofer, amp, LOC, RCA cable, amp wire kit, T harness, ANC bypass, speaker wires, & remote turn on wire. I also added sound deadening material & subwoofer remote for my install.

Sub signal is best accessed off the Bose amp...you will need T harness to do this....just plug n play. I have an extra T harness if you're interested...$60

Can you send me a picture or post one? Does it T off before the amp or after? The amp kills bass as volume gets high, doesn't it? I have all the other parts, but I'm considering the L2Ci thing

I have one of these SNI-35 on Amazon, will it still work with your harness? If so DM me and we'll get in contact

I wouldn't recommend using that LOC from Amazon....you'll have to cut n splice into the factory speaker wires/harness. I'd recommend LOCs from AudiControl and Wavtech. I went with Wavetech DQ for the price, size, bass adjustments, and positive reviews on Crutchfield.

Using T harness is as simple as it gets...plug n play. See attached pic of sample setup. T harness gets you full audio signal from front speakers AND 12V source/ground for your LOC. AudioControl or Wavtech LOC will also give you amp remote turn on signal.
