NVX Boost Subwoofer upgrade - installed

[bo3bdar]

That's a strange and bad design for that Boost box on the Model Y. Odd, because the ones they make for Model 3 and Model S are really good.

Having it not fill the space vertically, and clip the speaker at the rim edge just looks sloppy and bad. Not even taking into account it doesn't fit properly anymore and crimps the grill. Why did they not move the speaker up and make a bigger box to use that otherwise wasted space? Strange.

Might be worth pinging their support people if you haven't already. I've had fairly good experiences with them.


Model 3 variant for comparison:

Yeah, I had it for my Model 3 too and the fit/finish was excellent on that one

It seems their boost box does not fit the 2023 Y and will need some tweaks. Believe their website says it is for a 2020-2022 Y.

It actually says 2020-Up

That’s OK though, because now I’m on a mission to fix a bandpass or ported box for the sub trunk. NVX actually has a ported box for their 10” sub, but it’s slightly too large. Looking for something comparable - needs to be around 1.2cubic in total enclosure space (if just a ported box)

Wow, definitely need to update their site. Hopefully they will take back this box since you are going full custom. Their amp and LOC work great, but the whole point of the box is a great fit and good sound.

Whoever is installing this I highly suggest doing the bass knob and LOC separate. It’s vastly different in terms of song choices and bass input. I find myself adjusting both for each song for different bass intensity and resonance.

Also if you pair these with the alpines from HepaKing…you’ll hear a much a substantial clarity difference of mids and highs.

Post a pic of where you placed your “knobs” within the cabin.

I’m at that point of installation and I can use some inspiration. (Don’t mind how dirty the car is, is overdue for a wash).

Almost there….

Right at the drivers side against the seat. Easy to run the wires here and really easy to access when driving. Armrest is nice but you would be opening and closing it all of the time. You are so close.

Excuse the dirty car as well, dogs shed really bad!

That’s perfect. I’m copy you on this.

Mine are within hands reach along with my airlift controller, tank purge, and remote 12v readout with autoshutoff / touch control for accessories.

After playing with the remote knob for the LOC I don’t really see the necessity. It’s seems to be just another “volume” control and not really changing anything musically. That’s just what I’ve seen over the last few hours. I’ll keep for now since it’s already wired up.

 

[C-Bus Y]

Some songs are low on bass while others are bass heavy. You can dial in the bass song by song if you want. I use mine all of the time.

For sure I hear the difference of using the remote knob for the amp. I’m referring to also utilizing a remote knob for the LOC. I’m currently running both and I was just stating that the latter seems to just be redundant IMO.

That is slick, is this the wireless phone charging spot? Would love to hear more about your setup.

Oh good call, only run one. I use the LOC knob. To your point the other knob is totally redundant.

I think you mean you’re running the bass control knob from the Amplifier judging from your picture above.

I may have to try these if my subs fall apart.

I removed the grilles since they were causing a weird baffling noise, but then the speakers are starting to crack from pushing into the trunk trim side pieces. I've moved the trim pieces inward for now.

I also could not get that same trim piece to fit flush on the passenger side for the life of me. The combination of the subwoofer grille, the additional signal and speaker wiring definitely do not help at all.

Hmm, I came from underneath the support beam and the piece went back like stock…because there was nothing in the way.

Some shots of the wires going under the beams then coming back up.

Yeah, I saw that in one of your pictures you had a void to be able to run the wires underneath. That void no longer exists on later builds. See below.

 

[C-Bus Y]

Well snap, how about that. Does that black plastic piece come up to run the wires under it or can you put some small holes through it to run the wires? You can also go under the rubber piece along the side towards the front then take a hard left
