Anyone know where the bose amp is located?

Behind the rear seat, toward the passenger side.

I’ll be installing the JL Audio Stealthbox with the Dual 10s. HD750/1 amp and an HD600/4 for the door speakers. LC7i for the LOC.

I am planning on building an inline harness that will intercept the factory radio plug and will feed the speakers from the radio.

I’ve got everything needed for this install, but have not time. LOL. Hoping I can get started next week.

I'm planning on running a very similar set up. What's the ballpark cost for something like this?

Amps were about $300-$400 each. I bought them off eBay. The stealthbox dual sub, I bought from a local member here for $600 (I think). The LC7i was about $125. I spent about $100 of JL Audio Cables and such. Another $125 for the JL Audio amp kit.

I’m probably about $1600 into it.

Still haven’t started the install yet. Waiting for good weather, time, and undecided if I want to sound deaden while I am at it.

Following.

I have a 18 Silverado 2 LTZ with the 6.2L Bose (with noise cancelling).

Already have :
2 12'' subs (Kenwood Excelon KFC-XW1200F)
1 amp Kenwood Excelon X801-5

Looking for a enclosure and input on anything else I need.

Put them on the box, otherwise your going to have to remove the back seat to adjust them

I am still torn on mounting the (2) JL Audio Amps on the space provided by the stealth box or to the back wall.

Anyone wanting to splice into OEM harness, there is a kit for this. I just purchased one and it's as simple as plug and play.
It plugs into OEM Bose amp and then the OEM connector plugs into other end with wires to connect a amp and also had the ANC defeat harness.

Subthump.com

They also have subwoofer boxes for under seat.
Great products and quality A+.
