So I plan on installing a subwoofer in my recently purchased gx460. I've been out of the audio game for over 8 years now lol.
here is what I plan on getting installed
1.amp Rockford Fosgate T750X1bd...
Hopefully it can fit with a custom bracket where the jack is. Its a pretty small powerful amp
2. 1 kicker 12in l7 shallow so I can still optimize the 3rd row if need. Don't down it i want down firing or standing
3. Audiocontrol line out converter to run of the stock radio. And hopefully that can fit in the same area as the jack
Any other suggestions on a setup that can be almost stealth. Would be helpful or location to hide amp
I have the 12in downward firing kicker and no complaints here except for that I would prefer 2 rather than the 1 I have lol.
my amp is under my driver seat and the line output converter is coming out the factory inputs under the passenger seat. There’s a plug and play style adapter so you don’t have to splice into the factory harness. Definitely recommend it so if you need to bring it to factory specs it’s literally just a harness removal.

I am guessing the plug and play option is with the ML system? Or does the base system have something under the seat?
I was looking at getting a little self-contained woofer thing for under the second row seat, and need to figure where to tap in.

My truck came with a 10" subwoofer in a funky plastic enclosure, mounted behind the plastic on the right on the back. Perhaps you can fit something in that location? Or buy a used factory sub, and install a better woofer in it?
I removed the 3rd row seats, and I'm installing a 3,000 watt system, with a custom built subwoofer enclosure shaped slightly larger than the 3rd row seats folded down. I'll post photos soon, for reference.

Quick little update..
I got the lc2i
And I got the Rockford Fosgate T750X1bd amp... wow Im loving how compact this amp is...almost fits in my hand
still undecided on the sub
I have this same sub / box in my '22 GX, and it hits hard for a 10". I've got mine running off a JL XD600. Good luck with the install....post pics when you're done.
Ok everything is done now...
installer was super surprised on how powerful the amp was. Amp and line out converter are under driver seat.
I know the sub is upside down... I needed it on the left side incase my daughter wanted to sit in the back.and the outputs run on the left side.i have enough slack to move it to the right side if ever need. This set up hits hard and clean. I ran nothing but kicker subs in my ls430s before. They hit harder but dont sound as nice as jl audio
