The setup is awesome. When I had my 19 Silverado I was running all sundown speakers. 2.75 in the dash, 6.5 components in the front doors and 6.5 coals in the rear doors. Used the D-6.1200 to power those. I had a pair of 10" sundown Audio E series under the rear seat powered by a 1500W mono block also from Sundown. It was pretty awesome. Sold the 19 Silverado and picked up a 21 AT4 3.0 Diesel. Changed the setup a bit. 2.75 sundown's in the dash, Sundown 6x9 in the front doors and 6.5 coals in the rear. Running the JL Audio Stealth box under the seat powered with the Audio Control LC1.800 amp. I miss the sundown subs if im being honest. Wish I never sold them.
just ordered one from the dealership off a 2020. fits perfect and fixes that sag in the middle. You will also need 2 bolts, one at each end under the front fenders. Took 10 minutes to install and you only lose about an inch of ground clearance.
I did this exact setup on my AT4. Using the ready lift blocks in the back and the shocks all the way up the front sits about a half inch lower. I am able to fit 20x10 wheels with a -19 offset with 33x12.5.20 tires with zero rub. It is close, but fits.
So, no exactly your setup, but I installed the Ready Lift SST kit with the front Bilstein 5100 shock on my 21 AT4 with the 3.0 Duramax. I put the clip on the shock for max lift and added the 3" rear block to the back. I have about 1" of rake and am able to run a 33x12.5x20 without any rubbing issues.
Went from a 2019 Silverado with black and grey connectors to a 2021 Sierra with black and grey connectors. Because the connectors are the same I would assume the pinout is the same. Dash - Sundown Audio 2.75 speakers crossed over at 125hz to 20khz Front Doors - Sundown Audio 6x9 coax crossed over at 45hz to 20khz Rear Doors - Sundown Audio 6.5 coax crossed over at 65hz to 20khz I have tried opening up the crossovers 20hz to 20khz and it made no difference. Also, once I get my subwoofers figured out I will have to revisit the current crossovers. On a side note, these sundown speakers are awesome.... Incase anyone else is reading this and is interested, I also purchased the Soundskinz custom cutout sound deadening and that works great as well.
No chimes and alerts. Non Bose with black and grey connectors. I mounted the amp under the back seat and made my own bracket. I will attach a pic. Not using front high. Ran separate cables for dash speakers running directly to amp. front and rear door are using the LLJ Customs loopback harness. Ran this exact setup on my 2019 Silverado with black and grey connectors on my 2019 Silverado before trading it in and I didn't have this issue. Same harness, amp, speakers. Scratching my head on it.

So I installed an LLJ Customs loopback harness into an Audio Control D-6.1200 amp. For some reason my blinkers are silent now. Anyone have any ideas? LLJ never responds to messages, emails or calls so not sure where to go from here.
Not sure if this has been posted or not, but I have been watching for 5160's to come back in stockmfor my AT4 Diesel and stumbled across this... https://www.bilstein.com/us/en/product-search-detail/?ItemId=2972832273118789803&YearId=4728741073082748634&MakeId=3406203325310476397&ModelId=5679221949025775276&SubModelId=3003517839329353585&EngineId=3466895969683645431 Looks a lot like the ready lift ones, but thought it was interesting.
1: Audio Control D-6.1200 Amplifier with ARC3 controller 2: 300AMP Stinger circuit Breaker, Stinger Distribution Block, Stinger power/ground wire 3: LLJ Customs loopback harness with 20' leads (Black and Grey connectors). This length allowed me to go down the driver side so the wire did not lay next to the power wire. This is a complete setup to install a dual amp setup in a 2019 and up Silverado/Sierra with the black and grey connectors. I sold the subs and mono block separately.. Price is $800 and I am in the DFW area. I will ship at buyers expense. You can message me here or email me at [email protected]
So, not sure if there is a for sale/trade section but I have some gear for sale. 1: Audio Control D-6.1200 Amplifier with ARC3 controller 2: 300AMP Stinger circuit Breaker, Stinger Distribution Block, Stinger power/ground wire 3: LLJ Customs loopback harness with 20' leads (Black and Grey connectors).

I went with all Sundown Audio Speakers. 2.75 in the dash, 6.5 components in the front doors and 6.5 coals in the rear doors. First time buying SA speakers and I am really impressed with them.
