Custom Made T-Harness for BOSE - Compatible with 2019-2023 GMC Sierra - Chevrolet Silverado Vehicles

The easiest install ever thank you guys

Product was made with quality material easy plug and play for those who want to add a seperate amp for sub

Couldn’t be any easier to plug in an aftermarket sub to the factory amp.

Product works great, seemed to be made of premium materials, only downside was the long wait time to get it, shipping said 4-7 business days or something along the lines of that and I waited about 3-3.5 weeks to receive the harness. Worth the wait, just frustrating.

Literally plug and play. Requires no tapping into other wires. Love it!

Product was as described! Build quality was great and shipped in a timely fashion. I got it in roughly a week during the holiday break. Initially I did not think the fitment was correct. The harness would not fit the oem connectors. Eventually I removed the red piece in the picture and was able to force the harnesses together before reattaching the red connector. This harness allowed me to add a mono amp me to the existing oem system. It provided me with a remote turn on and rca outs to my lineoutput converter (loc might not be necessary if your amp can receive 6v rca inputs?) No cutting/splicing was required, and it is easily reversible without any signs of tampering if you need to uninstall it.

The harness works great. I called and talk to a representative about my needs and told him the setup I was going to be using and was told that I would need this harness setup and it worked like a charm. Thanks and please buy from SG..

The harnessed worked outstanding! No issues with the product at all! I did have an issue with shipping.. It took nearly 3 weeks to receive the harness after payment. I had to send multiple emails before I was told there would be a delay. Besides the shipping and waiting period, happy I made purchase.

Used this harness on a 2022 Silverado w/Bose system, and it was one of the easiest amp installs I have ever done, no wire cutting or splicing. Hardest part was removing the back seat. Shipping was quick.

For other customers, this harness provides switch power and high level speaker outputs, web site does not have allot of detail.

Would recommend this harness and Sound Good Stereo to anyone that has a need for this harness.

I'm running this harness in my 2022 GMC Sierra AT4. It really was the easiest part of my install. This is a true plug and play adapter that gives you a simplified solution to mount your sub amp. The remote turn on wire is a huge benefit and made the job that much easier, and wiring that much cleaner. I'm still not sure if it bypasses the Active Noise Cancellation though, but so far, I have no complaints. The customer service has been great too. They called me after placing my order to verify how long I needed the RCAs to be. I've never had a company do that. I'm a returning customer for sure. Highly recommend!
