NEXT LEVEL Audio upgrade for Bose w/ Kicker Sub - How-To 

I wish I left my floor mat alone. I figured since I would have to cut the X in it for the wiring anyway, may as well cut the whole thing.

@@DemonWorks I cut no carpet either

@@jeff-9322 ah, yeah, I cut mine because I wanted that clean look. Seen some that just have wires hanging out. I’m assuming yours is well hidden, though.

hows it sound ? do i have to cut the floor liner? does it face up or down

@@7474. It sounds ok, wish it had remote control. I did not cut floor liners and fit perfectly fine. Speaker faces down

I agree. I installed mine with all the dip switches set to factory and it sounded ok. But with the controller knob and all the dip switches up it’s a huge difference. Sounds so good and like you said it doesn’t mess with the Bose speakers 👍🏼

That’s how I would have done it. Let the sub handle the bass, not your speakers.

check out 1:39 for the part number I used.

I order one for my 23 AT4 but it’s a dealership add on so they will be installing it when it arrives, I also order the knob so they can connect it.

@@dcarr4842 Good luck with the knob, doesn't look like they work anymore

​@@jeff-9322what do you mean?

Gm accessories is currently offering 20% off for the month of June. $75 to have local dealer install

u end upgettign it how is it

It can, wish I attempted that first .. just need to route the wires to fit, but there’s room.

@@DemonWorks thanks for the quick reply!

Definitely a larger system than this.

@@DemonWorks and $1,000 more dollars 😱. I also have to buy an amp 😱

Which JL system is that?

I have the bose system but unaware of a console mounted sub.

Yes console. But it's barely there. My 21 Mazda Bose system has a sub that's useless as well.

It does, that’s where one of the connectors goes to.

Power wires went through the firewall where they attached to a connector that is part of the main speaker box harness. So, the speaker wires all started at the front passenger area where the ground was connected and the speaker wires were tapped. Then that harness ran under the seats on the right side and around to left rear and connected to the speaker box via 2 connectors.

On a 2024 there is no black tit in the engine bay. Wire go through the white connector

@ivansantos7762 Huh huh huh, you said “black tit”.

2 of these kits will not fit, you are better off going aftermarket.

Depends on how you run the wires, I’m sure they will route on top as well.

Yes. Safer for me so nothing gets stacked on top of the speaker ( I have kids and dogs)

is that how they tell u to install it ?t @@DemonWorks

@@7474. yes

@@DemonWorks thanks man

Small

Full bose system 100% functional. This is the gm upgrade kit.

this one will not, you need a different one that includes an amp and a lot more work, unfortunately.

interesting i have a non bose and online says the $750 one fits and is fine per my vin@@DemonWorks
