Subwoofer box

[18apetrella]

I have a 2019 Model 3 SR+ and audio is one of the things I've been upgrading. I connected the unused speakers with a wire harness, installed the NVX boost and just installed light harmonic front door speakers.

But with the light harmonic front door speakers also came an upgraded 8" subwoofer that fits the OEM sub if you have premium audio. Are there any boxes out there made for Model 3s that go in the sub trunk? Or would it be possible to buy a used OEM subwoofer box and put this sub in that box and connect that to the amp used to power the NVX boost? I don't know much at all about audio.

Not sure if there are pre-build enclosures out there, but just to give you an idea: my car audio specialist made one for my Model 3 to meet the subwoofer specifications. This is the 12" JL Audio TW3 D8 which is perfect for small closed sub boxes. I must say that I almost overhauled the entire OEM audio setup, so this may not be something for everyone.

Nice Helix V12. I went with a V8 in my Model 3. Did you do any of the speakers as well?

Thinking of doing the light harmonic woofers well. I have the Hansshow version F and am thinking the sub woofer will fit in the added subwoofer enclosure.

Yes, I did. 9 speakers including the sub have been replaced. The upper dashboard ones (below the windscreen), the upper tweeters, the doors (for kick bass) and the rears (below the rear window). I went with the Audison Prima series, and added German Maestro metal dome tweeters. Oh and added about 20 pounds of isolation material to deaden and silence the doors and roofline. Best setup I've ever had, it's a real compliment for such a silent car, especially with the Tidal update.

how much difference does the isolation material make to roadnoise? and how do you silence the roofline - thats all glass?

I did all sound deadening and audio upgrade by myself a year ago, and recently paid someone to do alcantara roof + roof pillars sound deadening.

I have to say the car now is much quieter than ever, the roof used to be rattling like crazy with the heavy bass, the sound deadening material could filters out most of those small annoying rattling/external noise/wind noise/motor winding, but road noise cannot. I have quiet tires and wheel well sound deadening done, it cuts maybe only 10% of the road noise.

Not perfect, I am happy with the result

It makes a difference, but not sure how much. It is noticeable though, but the primary reason for doing this in the first place is making sure nothing rattles due to the kickbass in the front doors and the subwoofer in the trunk.

Ofcourse I mean the roof pillars, not the whole roof. Most of it is glass anyway. There is a lot of wiring and airbag stuff going on behind the pillars that don't like heavy bass very much. Parts of it are done by fixating wires with tape, most of it is treated with audio specific adhesive aluminium coated dampening foil.

Basically the Tesla is more quiet than it already was (without any music playing) but totally worth the investment (and an absolute necessity) in terms of HiFi Audio installs.

SHOOT. im sick of trunk and front door rattles from having the bass up. I have managed to strategically wedge felt tape in certain rattleareas but theres still a few songs which love to rattle the system. i have no rattleing from pillars etc. its all just the door trim and the subwoofer trim.

The horror half-way through the project

What amp did you use for your subwoofer?

Mosconi Gladen One 240.2 (bridged)

Looks good.. I had debated on adding deadener to the sub trunk (where I just installed my JL Microsub+).. but considering it's basically an echo chamber otherwise I figured why not. Did you notice any difference with it?
