H/K Amp & Speaker Breakout Harness

Yes, you would just cut into this harness for your install instead of the factory wiring. If you plan to keep your aftermarket equipment when you finally move on from your Telly, simply remove this harness and plug the factory connector back into the amp and it's right back to stock.

There was a min quantity purchase for the connectors so I do have extra parts on-hand to make a couple more harnesses if there is any interest out there in the community.
Hi, I'm very interested as the part is only available for models until 2022.5 and I'm driving a 2024 and the sound is very, very bad.
Any options to get a harness from you?
Thanks!!!!

I'll be happy to Venmo or Zelle you.
Thanks
 
Like others here I am reluctant to cut/tap into the factory wiring for the audio system and since I could not find one commercially available yet, I went ahead and made my own breakout harness for the Harman Kardon amplifier in my SX. I plan to install a new amp/dsp in a few months and this was the first step in my process. Bottom line it permits installation of aftermarket audio components without cutting/tapping of factory wires while also maintaining full use of that same factory wiring for speakers (we've seen elsewhere the challenges of running new speaker wire out into the doors). Thus far it works flawlessly with all channels intact for this particular connector...the center channel and front tweeter channels are located on the 2nd amp connector (w/inputs, pwr, gnd, etc), but I do not plan to use those in my future setup (disabled and crossover, respectively).

Are these still available from you? I really like to buy one!
 
Hey, I need this harness, here in Canada. How can I make one or buy one?
 
@HLXHLX: would love one of these harnesses, or at least the part numbers.

TIA

@HLXHLX if possible, I'd love to snag a harness. If you're out of the game as far as making them, a direction to the connectors would be great! Thanks!
 
@HLXHLX, I also would like to purchase a harness from you if possible! Thanks in advance for your time.
 
BTW, I snagged one of these harnesses - very clean work - haven't had a free moment to complete my installation, however, I'm pleased I don't have to hack up that harness in the car.

I'll be hitting the other harness a bit, but that's on me - ;)

Just to clarify, is this harness adapter for factory head unit output to amplifier input or is it for amplifier output to speakers?

Hello new to the forum and Telly community. Just got myself a black 2021 ex premium nightfall. Definitely looking to get one of your harnesses asap. I can’t seem to message you. Thank you

This is for the H/K amp outputs, so speaker level. It's called a "breakout" harness so you can directly tap it for signal or add aftermarket components AFTER the H/K amp while still having the option to utilize all the stock wiring.

I would like to purchase. Please message me

@HLXHLX I'd also be interested in a breakout harness if they are still available. I have a Helix DSP and a couple Stereo Integrity amps I may try to install if they don't go in my other car.

@HLXHLX count me in for a breakout harness also. Got my 2024 SX X-Line last Friday, love it so far, but it needs some BASS! Please PM me with details and payment info.
 
Rather than start a new thread, figured I'd post my system update in here since this is where anyone who's looking would come.


I didn't take great pics during the install, but did take some. I did the install 100% myself, and I've been in and around 12v since 94 or so. I custom made the door baffles for the speakers and tweeters, and used solder butt connectors for all connections EXCEPT when I needed to be able to unplug something (rear door tweeter, for example, when you remove door panel).


Front stage is a set of classic MB Quart Q series separates - QM218 6.5"; Rear stage is a set of Focal 6.5 Performance separates, with a Kicker 200.4 DSP amp powering them. Have a JL Audio slim 8" in the back powered by an AudioControl 300.1 DSP mono amp.




I went through my pile of AV gear, and it turns out I have an AudioControl LC6i Line Convertor that I used to use, but no longer.


So, I grabbed the signals from the front tweeters, the front woofers, and the rear speakers, input them all into the LC6i, summed them all to the Main Output, and ran them into the Kicker DSP amp. The LC6i can drive up to 9.5V, but that clips a bit, so after tweaking it, now we've got a VERY complete signal with the ability to tweak high, mid, and full PRIOR to the amp, and then the DSP on the amp gives it a solid curve, and tons of clarity and volume.


When I did the amp setup, I purposely clipped one wire for the center, and one wire each for the surrounds to pull them out of the equation when doing DSP (didn't want them playing pink noise).


The result sounds amazing, super clear, and I got my tones back. I went ahead an reconnected the surrounds and center to fill the car out, and I like the stage that way. The fronts are so much louder anyhow, it's really just background.


Your harness made things quite a bit easier.
 
Any pictures of the installation or end result?
