Nice unit

Worked very well. Definitely not factory ends as they are a little hard to connect. I liked the idea of not cutting any wires on a brand new truck.

Hassle Free Plug and Play Harness 20 Silverado LT Trail Boss W/ Bose

This is a great and easy way to add some BASS to your truck, without having to cut and splice,. Super clean and well made. SG for the WIN again.

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.

W

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.

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.
