the xv amp doesn't need the LC2i. I believe the rear speakers are the ones to tap into on the newer systems. Thats one reason i stepped up to the VX amp is so i wouldn't have to mess with the LOC or nav tv.

The 750/1 kept clipping and shutting off. The VX amp works way better than the hd amp did.

Got everything done with yesterday. Unfortunately they did not take a pictures. I have spent the last several hours throwing every type of music i can at these subs with the new VX amp. Have not had a single hick up yet. I am ecstatic with the sound system again. It could have just been a bad JL 750 HD amp. But since i moved up to the VX1000 i am beyond happy.

As of right now, not using a fix 82 or a loc. Spoke with JL and they said with the VX line of amps, i will not need anything else.

I'm getting my JL VX amp installed tomorrow, so hopefully no more issues for me.

What version is on your infotainment system? When mine was at V805 i didn't have any issues with my aftermarket system. As soon as it updated to V807, my focal amp died. Just curious if this is more of a GM problem then with my aftermarket equipment.

what issues have you had with Nav.tv?

be nice if the nav.tv wasn't so damn expensive.

JL has told me that with the VXi amps, i will not need the LOC or the fix. They did however recommend the NAv.Tv

so when i go to the VXi amp, will i no longer need the loc or the jl fix installed?

because the current JL750HD amp isn't working properly. Has never worked properly. So i am upgrading the amp to the next level, and why i'm at it i am also upgrading to the fix82. Next step is getting the Nav.tv if i have to. I am not familiar enough with what the VX amp can or cannot do.

opened the amp up over the weekend. Everything was set correct, i played around with the gain and the sensitivity dial. Never found the sweet spot. I'm thinking it is a bad amp. I have a JL fix82 on its way to replace the loc22 that is currently in there and then a new JL VX1000.1 to replace the current JL HD750. We are on a lock down know for our county, so it might be a few weeks before i can get this done.

thanks i will open the amp up and see what the settings are at.

Thank you for your feedback. It is not an aftermarket head unit. It is the stock infotainment system. I was originally at v805 and it updated to v807, thats when my focal amp bit the dust. I'm thinking it has to be from the update. Don't really want to spend the money for the nav.tv unit, but if its a must then its a must.

ground wire is tight and has a clean connection to the bolt holding the seat in place.

I do not have any blown fuses. I will look to see where the amp is grounded when i get home from work. If it is the ground wire, would the subs work to a certain point and then stop?

no ideas from any of you?

Not to thread jack this. Here is my current issue. I have a 2019 LTZ with bose. Back in november i had a local car audio place install a JL stealthbox. I was at the time using my old Focal 1.800 amp. In the middle of january, i had an update on my factory head unit. It installed the update while i was at work. When i went to get in the truck after work, system turned on but no base from the subs. Come to find out, my focal amp had died. Fast forward 7 weeks and i have a new JL 750 HD amp installed. They are having one hell of a time getting it to sync up. If the volume gets turned up too far, it starts clipping the system, and then shuts off to protect the speakers. This is really annoying. I know have over 2500 spent and can not listen to my music very loud. Any ideas from you all on why this would be happening? Is it a bad amp? is the update to the factory unit creating all the problems?
