Where did you guys ground your amps? Any Pics?

I used a self tapper into the third row seat frame. Easy to run the ground cable out of the front of the cargo tray and right into the space under the third row seat. It’s invisible and doesn’t interfere with the seat mechanism.

That's the price that it gave me ($122), but the shipping was something like $80. If you get the whole thing <$200, you've done well. Good luck!!

FYI for anybody still looking at these you can skip the $80 shipping and buy this bad boy on Amazon for $148.85 right now and free shipping.

Did you end up replacing the speakers or are you still using the OEM Bose speakers?

Hi All - In the process of getting parts together to install the JL Stealthbox in my 2023 RST. I have the 9 speaker Bose (non dash speaker), and am trying to confirm what T harness I need.

I found one form PAC but it says it’s not compatible with my car. Can someone confirm what T harness they’ve used and share a link?

I know this is an older post, but how much was the front row conversion? I have a Tahoe RST and I would love to have a 9th seat. Where did you find the parts, and how did you get matching upholstery?

I decided to go with the stealth box, I don’t have time to fart around with mating a speaker to the Escalade box.

The LC2i almost threw me for a loop - when I was setting the sub level it kept clipping really early until I realized the main level out was also up… they should have you turn that down in the instructions.

it took a good 15-30 minutes to set the accubass, loc out levels, and the amp input level. I used an ANC termination harness.. worked like a charm. I left the loc knob by the jack access since I don’t foresee adjusting it all the time.

Sounds fantastic. Let me know if anyone has any questions.

With ANC disabled, is the cabin noise any different? I enjoy a drive without music or played low every now and then. Just wondering how much of difference this makes.

For me, it was a good thing. I used an ANC harness, so it can go back to stock when it is traded.

Things I noticed: engine sound is louder. But I enjoy the V8.
Wind noise: seems to be no difference.
Road noose: maybe a smidge louder, but my A/T tires are relatively loud anyway so it is hard to tell.

Biggest difference is I don’t seem to get as tired or sleepy on long drives. Don’t know if it was the ANC, “pressure” from the speakers fighting the noise, or what.

I tend to like a sensory driving experience. I want to know what my vehicle is doing. In the end, I couldn’t tell much difference except the engine noise is better.
