Sundown Audio Speakers Series

  • X v.2 SERIES

The Nightshade line from Sundown is their vehicle based WMD series.

They are powerful, thunderous, apocalyptic heralds of the end of the world.

I wish I was exaggerating, but when you see or hear the impact that these subs have on the human ears, body, and brain, you will understand.

They aren’t literally earth shattering, but if you ever hear these babies amped up and pounding live, you will definitely have your doubts about that.

NSV3 SERIES subwoofers review

These are near-professional- competitor-only grade subwoofers with a price tag to match.

I guarantee that no one else on your block, in your city, or possibly on the same continent can rock something this powerful in a car stereo though.

Be prepared to do a bit of building for these as well, because they are going to need some industrial grade housings to stay mounted.

Sundown Audio Speakers Reviews

Here are some quick reviews of Sundown’s most popular subwoofer models.

Check them out.

Value and quality in a 12” package is nothing to turn your nose up at, and these EV3 subs can definitely deliver the goods.


  • Sensitivity: 86.4 dB
  • RMS: 500 watts
  • Peak Power: 1,000 watts
  • Frequency Response: 36.6Hz
  • Impedance: 6.1-ohms

The Good:

These subs have some serious rumble without necessarily outstripping the performance of most bass amplifiers.

Their sensitivity is decent for a sub their size, and their driver motor mechanism and voice coil are built to last even the heaviest use and abuse.


The Not-So-Good:

The impedance is higher than other subs in their class, and they tend to run hotter in terms of temperature for that reason.when blasting at full power.

The D2 model in the line has a lower impedance and better overall statistical performance, even if it may be a bit pricier.



Looking for more compact subs to deliver performance in a smaller space?

These SA-12s are just the ticket.

With lightweight aluminum frames and compact size, there subs are ready to bring some thunder to smaller spaces and enclosures.


  • Sensitivity: 84.22 dB
  • RMS: 750 watts
  • Peak Power: 1500 watts
  • Frequency Response: 33.96 Hz
  • Impedance: 7.07

The Good:

The size and weight of these subwoofers is impressive mostly because of how light and small they are compared to how big they sound.

Sundown definitely did their homework on these in terms of balancing size and weight with performance output.


It’s tough to find better sounding subs that can be so easily mounted in smaller bass enclosures.

The Not-So-Good:

While these are more powerful than most of the consumer grade subs, they are still a little short on power and performance.

They are a competition starter sub kit grade, but if you are looking to blow the doors off the competition in the big leagues, these subs are not built for that.



With these 15” subs, you are starting to break into the big guns collection from Sundown.

These are competition grade subwoofers that are lighter and smaller to fit into standard enclosures and vehicles without needing to modify either significantly to accommodate them.

  • Sensitivity: 86.81 dB
  • RMS: 750 watts
  • Peak Power: 1500 watts
  • Frequency Response: 34.88 Hz
  • Impedance: 4.61

The Good:

Nothing throws bass quite like a big 15” subwoofer.

They are the cheeseburger of the subwoofer world: thick, juicy, and satisfying.

These SA series subwoofers have a markedly lower impedance for cooler operation and better sensitivity, and they can handle sufficient power to put most other aftermarket car audio bass kits to shame.


The Not-So-Good:

While they are an improvement in terms of sheer thump over the 12” SA series, these subs are still not quite in the same category as the competition grade subwoofers that are on step up the quality ladder at Sundown.



Okay, now we are well into the competition quality bracket for Sundown Audio’s subwoofer lineup. The ZV5 series are capable of that earth shattering, heart-stopping sound of a natural disaster striking a landmass at full force.

You want to go to your state or local bass competition and have a shot at winning? These are the subwoofers for you.

Related: Best 12 Inch Subwoofer


  • Sensitivity: 85.3 db
  • RMS: 2000 watts
  • Peak Power: 4000 watts
  • Frequency Response:
  • Impedance:

The Good:

These aren’t subwoofers so much as they are sonic artillery.


You must built them an enclosure if only so that you can contain the sound into a general direction that doesn’t completely devastate the area within the blast radius.

The audio barrage these subs can produce can literally take your breath away.

The Not-So-Good:

Umm..the devastating power of subwoofers that could easily be used as an alternative method of riot control?

These are subs for serious bassheads only, and they are definitely not meant for anything beyond blasting bass louder than thoughts inside your head.
