Just bought this bad boy to add to my 2018 Model 3 LR AWD. Should fit nicely in the sub trunk. Thanks to all those that have spent their time adding information about the sound system on here. After a little research I have all the info I need to be confident with the install! I'll let you all know how it goes!

Test fit today. Perfect fit! Planning to do the install on Friday.

Today was the big day! Took me a little over 4 hours from start to finish including cleaning up. Everything worked the first time and I am thrilled with the results! With the factory sub I had the lowest EQ maxed and it still wasn't doing it for me. With this new setup I have the amp gain set at 50% and the lowest EQ set at 2/8! That's seriously all I could tolerate before I was getting a headache. LOL

Everything with the install went just as discussed on here, I really appreciate all the info! I did the full shutdown including disconnecting the negative on the 12V and disconnecting the DC-DC converter contactor. The only issue I ran into was breaking the two weird square clips at the top of each piece of side trim that goes around the back seat. Weird design, I'm not sure how you would release them without one side breaking. It still went back together well enough though, I think all the other clips will keep it in place. It was a pain to get those pieces lined back up though.

So far no errors or issues although I haven't even driven it yet, just played it in the garage. Let me know if you have any questions about the install process, I'm happy to help!

I've been wanting to complete this install myself for over a year now. I'm glad I came across your post and I'm glad you're happy with it. I was close to pulling the trigger on the NVX kit, but I'll trust JL subs any day over most. I was hoping to complete the install without removing the top part of the seat. Do you think that will be possible?

It's possible, but you can't really get the trunk carpet completely out without taking the seat backs off, so you'd be left to try and snake everything under the trunk carpet by feel. I'd recommend taking them off, it really wasn't that difficult. Two tips I learned the hard way, first, make sure the middle seat belt goes back onto the FRONT of the seat when you re-install it. Second, be firm but gentle when removing the side trim on the sides of the back seat. The top clip likes to break.

@leonar40,

Looks like you just tapped off the OEM sub with Posi-Taps and powered from the Penthouse? Assuming you have the Premium Sound?

Ski

Yes to all. That's what makes this install so great. It's like everything is custom made for you to tap into. It's still a lot of work but nowhere near as much as most cars where you are running from the battery in the engine bay all the way back and taking the entire dash apart to tap into the speaker outputs.

All the info that you need is in the long thread for the NVX subwoofer including the wiring colors for the OEM subwoofer.
