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.

Harness works great Plug & Play !!!!

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.

Poor management.

Placed an order a week ago and still haven’t received the item much less a tracking number or explanation of why it hasn’t been sent.

Harness works great on my 2018 Silverado.

This harness is nice. Just add a Line Output Converter to it if you have an amp that uses low level inputs.

I waited over 2 months from another company and only got a reply from them once I filed a PayPal claim. These guys had my order to me in a week.

This says it only works with 2019+ trucks, but I took a gamble on my 2018 since the pin out looked the same between them. Works great.

Perfect 2022 silverado refresh LTZ

After waiting 3 months with another harness manufacturer & being fed BS excuses i decided to cancel & look for other options. Wish i would have found SGS sooner & i could have had my system installed 3 months sooner. Good quality harness all plug &play. Ordered speaker level output and used an alpine MvR-500 didnt even need the remote wire. SGS will be my go to for sound eq from now on

Poor quality. Wrong pins. Didn’t work.

The two wires spliced were wrong. Not speaker wires. I had to cut and splice the correct wires. Waste of money. 2023 Silverado ZR2.

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.
