How To: Add 4 Channel amp to Jeep Grand Cherokee Uconnect system (MOPAR/Dodge/Ram/Jeep)

Recently added a 4 channel amp and decided to make a video showing how to do it on the Uconnect headunit vehicles such as my 2021 Jeep Grand Cherokee. Video was made after the fact so sorry for the lack of footage. Links to materials below:
47 ohm resistors:

9-wire speaker cable Speedwire:

Audiocontrol LC1i:
www.crutchfiel...
My system:
Mids: Rockford Fosgate punch 6.5 components and coaxials
Subs : 2 15inch Rockford Fosgate P3 in custom sealed box
Sub amp: Rockford Fosgate R2-1200x1 (1500rmw birthsheet)
Mids amp: Rockford Fosgate R2-300x4 (445rms birthsheet)
LOC: Audiocontrol LC1i

Thank you for the video... actually was working on a charger and they use the same radio... no signal when the speaker is disconnected... but you just showed me the path to success Thank you my good man

[@juliocajigas9361]

Thank u so much for the valuable information I’m in the middle of adding some sounds to my jeep and like u said u had a little bit of issues I’m not planning on doing killer sounds like u did and I’m not using fancy in line converter but I’m not getting any sounds at all I’m gonna try to put those things u put at the speaker wire so u connect can see some values if not then I guess I’m gonna get the fancy loc and do just like u did i have watched your videos like a 100 times already lol great information and u did a great job can’t thank u enough!!!!

If it’s the lc21 pro then no because it has built in resisters. If not, audio control has some resistors you could use that are easier to install than the 47 ohm ones from this video www.crutchfield.com/S-iEgsO5PFVSR/p_161ACLGD20/AudioControl-AC-LGD-20.html?XVINQ=GZ0&XVVer=18W2&awcr=628226871294&awdv=m&awnw=g&awug=9021731&awkw=pla-837273191696&awmt=&awat=pla&gclid=Cj0KCQiAorKfBhC0ARIsAHDzslu1v6_Xt5xr_NUHn_wsqD8cTebEZAjlcZu77Kf9m7kGpIZXCbuouQkaAvpNEALw_wcB

Hey brother, I have two questions! With doing this you pretty much are eliminating the factory amp and replacing it with a better one to get more power out of your speakers still running the original Uconnect radio? I have a 12” sub installed, and every time the car is off and for example I open the door to get something; the sub will turn on and go crazy if I don’t turn on the jeep right away. Do you know how I can fix that? Btw you have an is Instagram account? Thanks 🙏🏽

[@BigStuDolla91]

Hey so I have the stock speakers system with no factory amp. However this would have bypassed it anyway. I think u might have active noise canceling or something going on. Not sure but your picking up noise from somewhere. Maybe a turn on noise? I know with my system I haven’t had this problem

[@abarker9323]

Same diagram should work. The lc2i should already have a “main channel” just plug that into the highs amp and set it to 2vhannel input. This will copy the input to all four channels. Also, audiocontrol has “load sensors” that plug directly into the loc. I like these better than the way I did in the video

I haven’t had this problem. I would also suggest tapping the front speakers because they work better for this.

[@BigStuDolla91]

Wait why are you tapping speakers in this vid instead of disconnecting them?

[@charlesturner2116]

It's really strange. After I got my system all hooked up, my amplifier wasn't turning on. So I took a multimeter and found one side of the speakers I tapped into wasn't providing any power. So then I tested the LOC with the speakers that were providing power by running both the wires off that speaker and the amp turns on. When I turn the vehicle off, the door speaker that was working and providing signal to the amplifier stops working and the other side (door speaker) starts working.
