2023 silverado

Great product, works exactly as they said. Highly recommended for adding to your existing stereo.

Nice quality for the $$

I spliced into my wires on my 2022 and didn’t care to do it this time on my 2024 so I order the t-plug and it made it a lot easier! Plug and go !

2024 Trail Boss

Worked absolutely perfect for a 2024 Chevy Trail Boss with the Bose system. I have installed two of these in two trucks to add a sub, one with two 12's, and one with one 12. The harness makes it really easy to plug and play a sub amp into the factory system.

Plug and play

Excellent harness to maintain all factory wiring. No splicing or cutting of any wires just plug and play. Worked perfectly.

Great T harness. Plug n play. Easy install.

Great product very easy install. If you have a suv with ANC just remember to find and install an additional anc bypass harness. I found the harness at Crutchfield for $25.

Just like the factory harness

Easy fit and looks factory. Kept me from having to splice the factory harness.

Works Great!

I ordered this harness with RCA tips and it works great interfacing to the Bose system in my Silverado. It was all plug and play connecting my Kicker amp. Really happy with this purchase and I would recommend it.

Plug and play

Simply just plug into original factory bose amp and plug into aftermarket amp. Easy peasy lemon squeezy.

Truly plug & play..

Used on my 2022 gmc sierra refresh with Bose system. Harness was well built and high quality. .

Harness works great!!!!!! Plug & Play!!!!

Only one bad thing had to wait for it to be made they should tell you that ahead of time that there's a 3-week waiting period before they even ship it out. I actually had to call to find out where it was at and that's when I found out that they had to make it first and then ship it.

Description

For the Speaker Wire and RCA options, you will need to see if your amplifier accepts speaker-level/high-level inputs and how. For example, here are several popular amplifiers and if they accept High-Level inputs:

Arc Audio High-Level = RCA
Mosconi High Level = RCA
Kicker = High Level = RCA
New Alpine High Level = RCA
Older Alpine High Level = Speaker Wire
JL Audio High-Level = RCA
Audiocontrol High-Level = Speaker Wire
New Rockford High-Level = RCA
Old Rockford High-Level = Speaker Wire

Skar Audio RP Series High-Level = Does not have it, you cannot use direct RCAs from your factory Bose amplifier. You must convert this with our LOC option.

Sundown Salt Series High-Level = Does not have it, you cannot use direct RCAs from your factory Bose amplifier. You must convert this with our LOC option.

DD Audio M Series High-Level = Does not have it, you cannot use direct RCAs from your factory Bose amplifier. You must convert this with our LOC option.

Rockville = High-Level = Does not have it, you cannot use direct RCAs from your factory Bose amplifier. You must convert this with our LOC option.

etc. Check the manual of your amplifier or call them to find out if your amplifier requires a external LOC.

Any questions, please let us know and we can guide you in the right direction.

Excellent!!!!!

These fit my 2025 Audi q3 perfectly for a 8" midwoofer the factory used on my front doors!!!( These also fit my 2021 a4, b9 platform, but may need mod. if trying to use an 8? Maybe stick with the 6.5" for that model?!) The brackets arrived safely, and very quickly. They were packaged professionally with their ten87 design, vaccum sealed!!! Everything in the picture is included as well. These look, and feel superior to even what the factory can produce. Thank you Sage, and all the crew at Sounds Good for making your products available to out of State consumers. Do not be surprised if I order a back up, and 6.5 set in the near future.:-) thank you, Christian.

Great adapters

I love these adapters. They are thick and hold speakers like they should. You can even double stack them for that needed room.

Amp Rack 2020 Silverado Trail Boss

Nice amp rack with lots of options for mounting your amps, crossovers and DSP.. Will be installing this along with my SG Sub enclosure with 4 Audiomobile subwoofers, that I have on order. Looking forward to a intense listening experience.

Fantastic classic look with modern tech!

Absolutely love the 50th anniversary Kicker 15" subwoofer. I have a pair a 2 more arriving in a couple days! I just new when I saw these being released "And the memories the classic look gave me" I had to get 4 of them to rebuild an old system i once had with a full wall of Kicker 15's. Unfortunately being only a 1 year only anniversary edition kinda makes them rare with prices to eventually climb. Which means a single replacement if something happens is going to be an expensive and not easy find. I don't plan to ever sell them as I got a great deal and to me it's about nostalgia and the smile these put on my face just looking at them.
