Thanks. But still a bit confused, which is the Xover? Did you change anything on XLCA2 or just the amp? Is the Xover the LPF? Again sorry for the confusion and I appreciate your help!

What are your settings on the amp? I have the vadm1 that came in the package and not sure where to start on LPF, subsonic, boost, sensitivity or etc... Do I just turn them all down, play something, start with one until clipping, then turn back and then do the same on the next ones?

NVX thinks its a blown speaker they are sending another. I do have another question though, did you all leave factory sub installed or disconnect? Thanks

Ok so it is happening again, they are sending a replacement woofer. I do have a question though: did you all leave factory sub installed too or just unplug it?

so weird. It is working fine now. I had a software update the other day (first time Ive driven since the update this morning) and noticed on the eq sub and bass go up to 6, for a while they had "booming" or weird funny names like that, maybe it was a software snafu (eq set at a higher range than...

NVX is sending me a replacement, but do you think it could've been blown because of amp settings? It's not turned up crazy high or anything. I may need to borrow someone's nvx amp settings...

Just need to make sure it wasn't settings on amp that caused it. Anyone want to share their settings?

Thanks, they are actually sending me a woofer today ;)

I installed the nvx kit in Nov its been great, but this morning it sounds awful. Is this a blown sub?

Installed the nvx woofer kit in Nov 2021 for my LR model 3, its been great until today. Does this sound like a blown speaker?!?

I installed the NVX kit in November 2021. It has been great until today... Is this the sound of a blown woofer?!!?

Thank you!

@MapledLeif would you share your settings? Trying to get a place to start and not sure which to mess with first.

@m1xmstr Any chance you could share your settings? Looking for a place to start with mine. Thanks!

Did you ever come up with some settings? I just installed and would love a place to start too.

I got it installed! Now to tune. Any advice on where to start? Do I tune both xlca2 and vadm1? Any ideas on settings? Thanks!

I got it working! I made sure ground was ok, and took everything off amp and reconnected one by one. I did t realize the light I was seeing in amp was that it was going into protected mode. Red not it blue, so I think I had bad ground connection. All good now. Now just need to tune and put back...

So if I go direct to subwoofer from taps it works. So it could be: bad vadm1 outputs? Bad signal (bass out) from xlca2 to vadm1? Both power lights work and I see the bass light going off an on on xlca2. I called nvx but they are closed on weekends I guess.

Or do I actually do right positive and left negative?

To route to sub directly would I just take one channels (let’s say left) + and -?

I installed today. But no sound coming from subwoofer at all. Checked all connections 3 times and all seem good. I can get bass light or whatever on xlca2 to turn on if I mess with gains but no sound at all. Any ideas?

Any error messages since install?

Thank you! I have a LR. I will probably install to penthouse like nvx suggests. I’m just using the boost kit, no add-ons/bigger amp or etc. so should be a ok. I appreciate your help!

If I were to pull power from battery would it matter where I grounded? Or should I connect to battery for both positive and negative?

Thank you. I commented on the YouTube installation video and nvx said: “If you feel more comfortable hooking it up to the front battery go with that. Some have reported errors when hooking it up to the point under the seat. One the ones we've installed we haven't gotten any errors even after a...

Thanks. Did you ground up there too or by seat as in video?

He replied in the other thread with this, I am getting mixed signals for sure. I did read that most people haven’t had a problem connecting to penthouse. On the nvx YouTube installation video there are some comments saying it’s safer to connect to battery, but I’ve read a couple that say it’s...

Thank you!!

Thank you! Where did you mount amp and other appliance? No error codes from computer with this install? I’ve read some people say it’s best to pull all the way from battery up front others say no way just penthouse. Both sides say it’s best to negate error codes so kind of confused…. Thank you...

In another thread someone posted that it is imperative to draw from the battery itself rather than the penthouse so that the battery can be monitored better. But I’ve also read pulling from the battery is how the error codes show up…any thoughts/advice would be appreciated! Below is the...

This is great! Thanks for the write up. Any tricks you learned in hindsight about the jacknut and/or mounting the xlca2 and vdm1 (Ie location)? Thanks again!

Did you get it installed? Thoughts on the process and result?

Thank you! I am going to put dynamat in doors (front for sure, maybe back) and in trunk area. I am installing the LH speaker set 8 speakers including subwoofer and then I may install additional sub later (leaning toward the nvx kit) but will start with deadening and LH speakers and go from...

Thank you! I have premium audio in my model 3. So sound deadening did you put dynamo or etc in doors, trunk, behind pillars?

If you were going to start with one upgrade, which one do you think improved sound the most?

Did you install the nvx package with the amplifier or just the nvx woofer? Thanks!

Did you end up installing the nvx too? I was thinking of doing both the LH replacements and the NVX powered sub too. Would love your review/take.

Did you use the LH replacement package for all speakers? Really happy?

Thank you! Did you replace any other speakers? I was thinking of this nvx and/or the light harmonics speaker replacement. Would love your thoughts. Thank you!

Thanks for the great info. Did you replace any other speakers? I was thinking of this and/or the light harmonics speaker replacements. Thank you!
