Subwoofer addition

I'm fairly happy with the acoustic clarity of the stock sound system; however, I think it's somewhat lacking in the low-end response.

Has anyone successfully augmented their sound system with a subwoofer? Any recommended installers in the SF Bay Area?

Thanks for any pointers...

Just to follow-up and share my experience...

I ended up having an enclosed subwoofer installed in the side of trunk along with 5-channel amp tucked away in the frunk.

The overall improvement in sound quality is unmistakable. Range is improved across the spectrum, with (obviously) much fuller bass. To my ears, it sounds more 'satisfying' than even the upgraded sound system...and at a lower cost.

Installation was performed by Sound Innovations in Union City. They have experience with Teslas, and the proprietor, Ernie, is a very knowledgeable and detail-oriented. I highly recommend them. (See their Yelp reviews.)

So I take it you went from the standard system to an augmented system? May I ask the cost? I've heard so much about this Reuss upgraded system that ranges from $3K to $6K but that seems a bit of overkill.

A sub and an amp augmenting the standard system is appealing to me. Especially if it's around $1K.

That's correct. And I too felt that Reus would be overkill (for my needs).

The upgrade was quoted at ~$1500, but I opt'ed for a custom-matching fiberglass enclosure for the Focal sub, so it was a little higher. The end result is a clean setup that looks like it came from the factory, yet sounds *much* better.

Don't hesitate to talk to Ernie; he's great about presenting various options without the upsell.

Hmmmm....sounds cool. Any pics of the final product? Would love to see it!


I debated going with Reus, but it seemed like overkill for me too. I have one car with premium and one with standard and the biggest difference is definitely the subwoofer, and if adding a subwoofer improves the range of the entire spectrum, even better. Is that Union City, NJ or CA?

In my Googling for better sound I stumbled
on this NVX Boost subwoofer box that they made specifically for the
Model S. I know NVX is a fairly new brand, but I heard one of their
systems at a car show I went to recently and it sounded great and
they've got pretty positive buzz around the web. The pictures on the
NVX site show it installed and it doesn't take up much room and
actually looks like it belongs there. I actually gave the company a
call about this box and they told me that it's brand new and they
recently finished testing it out. The thing I was most concerned about
for it was battery life, and the guy I talked to told me that its
power draw is pretty minimal and really only reduces the mileage by
about a mile per hour of running it (at full blast). Anyways, I
thought this was pretty cool and wanted to share it.

The NVX looks pretty cool. Anybody know how hard it is to get the line level audio to that part of the car? Is that a DIY option, or am I asking for trouble?

$600 for a passive 10" sub that you have to install yourself? Hmmm.....

While the price is high, it's not a passive sub. You have to buy a amp for it as well and wire it up. With installation, I doubt you can do it for under $1K. Not sure yet if it's a DIY project as some info is still a bit hard to come by (the wiring). I hope to have some DIY subwoofer plans posted in the next month or two.

Still, it's nice to see companies spending the time and effort to make products specifically for the Model S.

Huh? I consider a passive subwoofer one that requires an amplifier for power. An active subwoofer would have the amplifier either built-in or at least self-contained.

Perhaps you meant "While the price is high, it's not an ACTIVE sub."

What protects the cone from cargo flung around while cornering?

There most certainly will be a grill on that speaker as a final finished installation step. It's uncovered mostly to show scale and placement.

@Thomas N - I was considering a passive sub one that has no amplification at all and connects across the left/right amp output (which is far from ideal). I actually have a passive sub at home from about 20 years ago that still works, but is rather pathetic. Never used for prime listening. I'd never recommend a sub without a sub-amp, either integrated in the speaker cabinet or outside the cabinet. I have no idea if your or my definition is the correct one!

I was also wondering about a grill too. Hopefully one will be included or it would quickly become a holy speaker! (bad pun intended)

Hey guys. I love to see the comments. I am the proud owner of the first one ;). The sub is not an entry level sub and provides plenty of headroom for even serious audio/bass enthusiasts. Additionally, the box is not a prefab wooden type enclosure. It was custom-tooled, engineered and designed specifically for maximum output without sacrificing any space. There is also an Active system that includes a monoblock amplifier. I don't know how anyone with a $60K+ vehicle would want a skimpy entry level set up :). I know I didn't hehe.

@nvictor - interested in the nvx... Can you tell us where you had it installed and the install cost? Or did you do it yourself?

For the DIY crowd, I documented all the details on installing a sub-woofer and amp in the Model S, along with the connection points which vary by the sound system type and date of build. It would also save a professional installer quite a bit of time to learn some of the tricks, so it might cut the cost a bit if you point them to these pages.

I used a Rockford Fosgate sub with a NVX amp, although if I had to do it over, I would have used the NVX sub too (it became available after putting my system in). I explain different install options, along with various links to get parts.

I think it's well worth it and I'm quite happy how it all came out.

WOW! What a detailed set of instructions. Fantastic!
