Elite Quality & Professionalism!!!

Bought the custom T-Harness for my son’s 2018 F-150 Supet Crew along with the custom amp plate for behind the rear seat! Both products were meticulously made, and worked flawlessly! During the install, I ran into a couple self-inflicted errors of which the customer service I received was absolutely impeccable and they helped me discover issues that had nothing to do with these products. I can’t say enough good about the products and the customer service that I received… I highly recommend this company not only for the products but for the customer service! My son‘s truck turned out amazing!

High Quality

Very high quality. Made easy work of adding a pair of amps to my factory system to drive the speakers and an added subwoofer. I ran this from my dash to a JL FiX 86 which corrected and cleaned up the output from the factory radio.

Cable is fantastic!

So pros got this for my truck so I can still use the back up camera android etc etc etc WORKS GRREEEEAAAT everything works as intended cabling is clean and long enough to reach your woofer in the back with a supercrew with 4 feet to spare! The labels for output and input are an amazing touch i waited about a week for my unit to get shipped out but not complaining there just more of heads up for folks who are gonna be impatient as the line is worth the wait and customer service hit me up said hey if you have questions hit us up and I did and they answered all of my stupid questions so kudos to the team for putting up with my BS

Some feedback:
The output and input collars are super appreciated I'd love to a collar denoting positive and negative(ground if you want to be technical) and possibly a custom collar labels if the customer specifys a specific way they are going to use the harness say for instance loading it into LC5I pro since I'm assuming that the primary customers are folks who are DIY and or newer to the whole vehicle electrical thingys

Outside of that i apreciate yall

Super useful

This makes the install so easy! Super clean and very well crafted. Cannot recommend enough!

Works great. Connected to 12.1” screen from GUA. Harness is a must have solution for the 2018 F150 non-amplified vehicles as the normal connector at the left rear of the cab doesn’t always have power or line signal wired to it.

Awesome product

Made my install so much easier, faster, and didn't even have to mess with hooking up a loc. My system turn out great, sounds awesome, and looks totally factory. Thanks guys.

2018 F150 harness

Great quality, and well made. Will definitely shop there again.

Super clean set up.

I have a 2018 Ford F150 with the T-harness and the sounds good stereo amp rack. Super clean set up for both. 5 stars!!! Recommend to anyone.

Perfect for first time installers

The T harness looks extremely clean. I’m doing my first sound system install and keeping the factory head unit. This T harness made my life way easier and was worth the money.

Tremendous Timesaver

I have been making harnesses for a very long time. This one, premade, made the install go that much faster. Fantastic build quality everything fit together perfectly. This single piece most likely saved me 3-4 hours of soldering and heat shrinking the solder joints. I would spend the money again in a n instant.

Product Description

Pick based on what you're upgrading

Complete Stereo Upgrade (most popular) — you're replacing all four door speakers with aftermarket. You get a full 4-channel signal off the harness (front L/R + rear L/R). To add a subwoofer amp alongside, pair it with a 4-channel amp that has RCA passthrough outputs — you feed the sub amp off the passthroughs without needing a second harness or LOC.

Subwoofer Only — you're keeping the factory door speakers as-is and only adding a sub. The harness delivers a clean stereo L/R pair pulled from the factory radio that feeds your sub amp. Factory door speakers continue to run off the factory radio, untouched.

Pick based on what your amp accepts

RCA Tips (High Level) — soldered Straight Wire RCA jacks carrying the factory speaker-level signal. Amp must accept high-level input through RCA. Standard on JL Audio, Kicker, Arc, Mosconi, newer Alpine, newer Rockford, Kenwood, Focal.
Speaker Wire (High Level) — bare speaker-wire leads. For amps that need speaker-wire input or for running into an external LOC like the AudioControl LC2i. Skar, DD, Rockville, older Alpine/Rockford.
Kicker KeyLOC Built-In (Sub Only) — includes a pre-tuned Kicker KeyLOC that flattens the factory radio EQ automatically and outputs clean RCA. No ForSCAN flash required.

One tuning note for non-amp Fords

The 2015-2020 Ford base radio applies a mild EQ curve and compression that you'll want to flatten before your final tune. Free fix: flash ForSCAN (Windows PC + OBD-II cable, fully reversible). Drop-in fix: pick the Kicker KeyLOC variant. Either way, your amp finally gets a true reference signal. An LC2i / LC7i will not fix the factory EQ — it's a level converter, not an EQ corrector.

Not 100% sure which variant fits your build? Call or text 615.610.1413 — 60 seconds on the phone beats a return shipment.

Must have for adding an Amp!!

Made adding a Kicker Keyloc to my F150 As simple as plugging it in! Highly recommend if adding an amp to your system!

Must have for an SQ build

If you are adding amps to a Bose system Silverado, there is nothing better. This bypasses the Bose amp with plug and play connections. I was able to add 2 amps with crystal clear digital sound. The end result exceeded my expectations. The instructions were a little hard to understand, I was able to call SG and they helped me figure it out. I would highly recommend this product

GREAT COMPANY AND PRODUCT

USED THIS IN MY 2026 CHEVY 2500 HD ZR2 WITH THE BOSE SYSTEM. PULLED THE BACK SEAT OUT PLUGED THIS INTO THE BOSE AMP PLUGED MY AMP INTO THE RCA FOCAL ADAPTER INCLUDED IN THE HARNESS I PURCHASED. STEREO SHOP GAVE ME A PRICE OF $400 PLUS $499 FOR AN LC2 THAT THE DEMANDED I BUY TO GET THE SYSTEM WORKING CORRECTLEY.
I PAID $185.00 AND DID THE WORK MY SELF SOUNDS AMAZING. HIGHLY RECOMEND TO ANYONE WITH A BOSE SYSTEM BUY THE FULL HARNESS WITH THE RCA FOCAL IT IS TRULEY PLUG AND PLAY.

Seamless integration

Without a doubt the easiest way to install an aftermarket subwoofer. Total plug and play, simple instruction, and pre configured for bass roll off. Highly recommend to skip the headache of tracing/ splicing into your factory system.

Improved sound

Easy to install, great quality and did improve sound of Speakers.
Definitely recommend!

Amazing product great service will highly recommend

Amazing product amazing quality sound these guys have done it again invested hard work and into making a great custom-made system for your vehicle thank you. We’ll buy again.

Fits great

Exactly what I wanted. It provides access to the door when you need to get at parts in the door cavity. Good sound proofing.

The perfect AMP rack

Great amp rack. perfect fit, great look, and fits everything needed behind the seat where it belongs.

Well Worth the Drive from Michigan

These guys are amazing to work with. I have a 2023 Ram TRX and was not happy with the factory sound system. I did a lot a research and talked to a few shops locally - not impressed. I talked to Sage and Don over the phone and email, and they put together a system for my TRX. I scheduled the appointment and made the drive to TN. They had my truck for a week. When it was done all I can say is wow. There are instruments in songs that I never heard before. The sound is crisp and clear. I now have even a bigger smile on my face when I drive it. This system involved replacing all speakers with Mosconi speakers and amps, sub enclosure, sound proofing the doors and tuning. These guys go above and beyond to knock it out the park. Thank you!
