[@jeffreyharbin5211]

do you have any harnesses that are meant for adding a bigger amp to a bose equipped system for powering speakers from a bigger aftermarker amp instead of the smaller bose amp? I have a 2006 silverado 1500HD with the bose rear dvd entertainment system that currently has an aftermarket touchscreen head unit with a 3700W amp and subwoofers hooked up separately from the bose system, so my 3700W amp powers the subwoofers under my rear seats and that's it, and all of the door speakers are powered from the bose amp however I want to have the door speakers powered from the larger 3700W amp but I am not confident in cutting all the wires coming out of the bose amp and rerouting them to the 3700W amp, I'm not 100% sure how the bose electrical systems are wired so this may not even be possible, but ideally I want to unplug a connector from the bose amp, and feed that connector to an apapter with loose wires that can connect to my amp to bypass the smaller bose amp, that way I don't have to run all new speaker wires to each door if possible I would also like the bose amp to remain in control of the door chimes and stuff so that when I open the door it isn’t extremely amplified are there any products that are meant for something like this?

[@jeffreyharbin5211]

I understand 2006 is a little outdated and since you guys opened around 2015 I doubt you will have designed something for the older models (that came out long before you guys even opened) and so if you guys don't offer anything for the older models do you know if any of the other company (such as PAC or Scosche) make a loopback harness for the gmt800 models with bose? I really wanna upgrade my sound system but all I can find are radio harnesses (the PAC module that retain chimes and steering wheel controls which I already have but I cannot find any speaker and amp harnesses)

Hello Anthony, our loopbacks do have a 3 week lead time at the moment as posted on the product. Loops from 9-8/9-15 will be shipping Friday. We hope to be down to a 1 week lead time on loops and 3 days for T-Harness styles by the first week of December.

Question - will the T-Harness work if I hook it up to a LC7i and then run the outputs to a sub amp and a 4 channel amp?

For that type of project i would recommend the Elite loopback system

[@mikeganard6751]

Do you have a video of how you would add and component set with crossovers?

[@nasoccerplayer311]

Thanks for the video, great stuff.I have a question about my current build. I have AudioControl LC7i Black 6-Channel Line Output Converter, 2 after market amps(4ch amp and 2 ch amp(for subs) connecting to a factory Ford radio(i have no choice of using an after-market radio). I'm running 125watt rms to the doors(4ch) so I will use after market speaker cable, not factory internal speaker wire. So with this, im thinking these speaker wires will connect from 4ch amp to the door speakers, which makes sense but my question is where does the 2 sub speaker wire connect from the LC7i to the harness(im using PAC LPHFD31 harness) as the harness will only have the 4 pairs, not 6 which I would need?

I have the loop harness using the lc5-1300 on a GMC Sierra elevation. I’m getting a turn on/off pop. What recommendations do you have to fix this issue? Thanks!

[@lljcustomscaraudiofabricat7854]

Hello Evan, thank you for the quotation. This is not an issue we seen with the AudioControl loopback. The pop can come from a late signal sent to the amp or a discharge of the amp but that is not usually the issue, its normally the remote signal will flicker turning the amp on for a second and it discharges the resting power in the amp. Check your turn on if you're using the auto turn on then use a fused remote to avoid that pop in some GM vehicles, normally the tahoes, but we have seen some Silverados and Sierras do it .

[@evandareaganon]

[@rafaelpureco1524]

So by connecting the rcas wires from the lc7i to the aftermarket amplifier for mids, your speakers already gaining watts from the aftermarket amp for mids , or what are you gonna connect on the speaker terminals from the aftermarket amp ? I don’t understand

[@lljcustomscaraudiofabricat7854]

Hello, on the output end of the aftermarket amp we wire in the return end of the loopback harness. This carries the amplified signal back to the speakers using the factory wiring.

[@tyslowandeasy2006]

If you ordered the loop harness and it hasn't shipped yet will you get the new style elite or will it be the older style

[@lljcustomscaraudiofabricat7854]

If the connectors are available for the vehicle in the elite system style it will be in the elite system.

[@I8591les]

I have a question once you have everything connected to the lc7i and rca’s connected to the amplifiers do you have to run new wire from the speakers to the amplifiers or is it already getting the signal from the lc7i

[@lljcustomscaraudiofabricat7854]

Hello Luis, If you plan to use a Loopback harness then the harness will have the signal for the lc7i then you RCA to tthe amp and from the amp you output back to the harness that takes it to the doors via the factory wires. If you use a T-harness or a similar device then you will need to pull your own wires after the amp

So for my 2018 GMC Sierra Bose equipped , what harness would I need to run an aftermarket subwoofer amplifier of my own choice

[@lljcustomscaraudiofabricat7854]

That would depend on the amp. If it takes a high level in you just need the harness if it only takes low level or you just want it to be ready for any amp you would get a link2 or lc2i or bassrestor. But like it was said if you plan to do only subs the bassrestor + the T-Harness is all you need.

I have both the AudioControl Epicenter and the WAVTECH. Let me tell you that the AudioControl Epicenter is good and can't go wrong with it, BUT the WAVTECH is BETTER!...

Hello Cooper, in your situation you would go with the 2014-2019 bose elite harness 2 channel with the i have my own unit option.

Have y’all incorporated any type of customer service number, not customer service email but a customer service telephone number that people can use to reach out and ask specific questions? Essentially, sometimes with a person, the customer may type out, makes sense to them however, whenever it is read by y’all, it may not make sense so therefore the message is not conveyed correctly. Quite honestly, this is what kept me from buying yawls harnesses for two different vehicles now because For a year straight they have no customer service number and only an email that in a one or two minute phone call could answer all questions rather than emails that take a matter of days to send and then wait to receive a response and then reply back. Aside from that, the site looks good and y’all got phenomenal looking products.

[@lljcustomscaraudiofabricat7854]

Hello Wrens, Thank you for the feedback. We understand the frustration that customers feel with our decision to not offer phone support. However when LLj customs was first brought to the internet we did have phone support and we where the only company at the time besides Critchfield, Sonic elec or taco tunes that both worked on cars and sold products with the installation information and it stayed that way for 3 years. We could not keep up with the phone calls and at the time CAN-BUS was coming into play and the complexity of the conversation and information that needed to be known created calls that lasted 1-2 hours. so the decision to communicate only via text and email was made so that a reference was created for both us and the customer and so they had the note of our discussion when tuning in case we where closed. As we grew we stared to get scammed for some of our bigger kits and so we had to create records . At the end of the day placing a CUSTOM product shop on the internet as a small company, came with a unique learning curve. As we continue to grow and expand our product lines we will be offering limited phone support in the future.

Hello, I am glad you guys developed these harnesses. I was about to add some speakers (initially subs) to my 2020 TrailBoss (with bose) but was not sure how and not mess up any wiring. Question: Does the loop back system going into Bose amp nullify the original amps (bose) output and then just provide your new amp systems output to oem speakers? If this is the case, if I am only adding additional speakers 2 subs and some extra mids/highs on top of existing bose system, would I only need the T harness plus the LC4.800 for example? Thanks.

Hello Jesus, Thank you for watching our video. so our products don't eliminate any factory settings or data. Our Elite Loopback Harness is what you would need it takes the high level signal from the bose and feed's it, in this case to an amp like the lc4.800 then will do the audio processing.
