I have a 2018 Chevrolet impala premier and I'm thinking of adding a sub and amp it has the Bose system. Will I need a line out converter as well or do I just need this harness please explain and help Thanks in advance
Great question and the answer is no you dont need an loc is the amp you are planning to use has the quality processor already built in .Otherwise yes you will want to use one
Do you guys make a harness for just the signal to come from an aftermarket radio straight to the door speakers via bypassing the amp? Example: I'm adding a Stinger HIEGH10 radio but i don't want to add amps, at least for now, just radio replacement and to bypass the amp, do you guys have any such T harness like that?
@deewilson1132 absolutely what is your question? Do you have the factory amplifier in the trunk? Even if it says not bose you will want to check for the amp
You should make one without loc so we can connect our own Lc7i or what ever I see you have the bypass harness for the speakers from the after market amp make one that comes from oem Bose amp to go to Lc7i or whatever
Do u have the 14. On premium system one my amp is in the middle rear trunk deck no rear speakers only 4 doors n 2 pillar tweeters and the monograph touchscreen non navigation xm Siri’s and on star tho please don’t wanna run cheap loc or have to cut wire in all over or replace hu
Hello Rich, you would want to use the bose amp T-Harness if you plan on just adding a sub . In a Malibu or impala with the factory amp. lljcustoms.com/store/ols/products/2014-2019-gm-bose-amp-t-harness
Does the sub-only harness also have a power wire (+12V or B+) to power the new sub amplifier? Or do I still have to run a separate wire to the battery to power the new sub amp?
Hi Chris, no the harness does not come with a 12v to power any aftermarket amplifiers. Only a 12v signal that tells the amp to turn on.so yes you will have to install your own fused power from the battery.
Thanks for the quick reply. I'm definitely going to order the sub harness soon. Do you by chance know where the closest 12v accessory hook up would be to power the amp under the back seat in a 2016 Silverado crew cab (with BOSE system)? Right now I'm only seeing the accessory post under the front hood, but nothing near the BOSE amp to power the new amp.
no problem, the Bose amp uses a 10 Awg power wire so you would have to be using a very small amp 200 watts or less to use 10 awg. The best and safest way would be to run a new wire that is the appropriate size fr your amp.
Just discovered your channel, very nice! Pardon my novice status if I may ask a question of your knowledge. I'm wanting to add an amp and sub to my 2016 Chevy Colorado Z71 w/Bose 6 speaker w/onStar. Not looking for window shaking boom booms just a bit more sound. What amp and low profile sub would you recommend? P.S. the sub is going to be in a custom encloser under the back seat. Any advice would be greatly appreciated.
If you are looking to just add a single sub i would recommend the Rockford P3SD2-10 with the ACM1.300 amp this a low profile system that is very cost effective and sounds great also do to the ACM amp having a built in LOC yo do not need to buy a High to low converter.
Hello Arturo, we have made some changes to the harness. it no longer uses 2 units it is wired to the lc7i in a T or Loop harness. lljcustoms.com/store?olsPage=products%2F2014-2019-gm-bose-amp-t-harness

I need the harness for change everything doors speakers and add subwoofers dash speakers what’s it’s the harness what I need for my Denali 2500 hd 2015 whit Bose system can you send the link please thank you guys.
How do you guys deal with ANC? If Your harness plugs into the speaker outputs at the stock amp then there will be ANC cancellation waves mixed in with the high level signal?
@@lljcustomscaraudiofabricat7854 Oh ok,you probably leave the 2 serial data wires in it that need to go back into the stock amp and leave the ANC module signal wires out of it? That would completely disable the ANC system cleanly without having to cut wires like a lot of hack shops do.You have some really awesome products for GM's!
@@Grayback1973 that is correct and it depends on the vehicles out new bypass will also work on the Cadillac's that have the center dash speakers on the same connector.
@@lljcustomscaraudiofabricat7854 People don't realize how long it takes to make these harnesses.Cutting and pinning the wires,inserting,soldering,etc....then taping them up like you do,dang!
