  1. BEAST

    Posted by (315) on 26th Sep 2017

    I just purchased a sundown SA 15 for my Ford Explorer. Boy this thing is no joke. Sounds way better then what i expected. Can't wait to get another 1...

  2. best subwoofers i've ever owned

    Posted by Brendan on 27th Mar 2015

    I owned a pair of these a couple years ago and eventually had to get rid of them. I wanted to run a pair of 15s again and I had to go with the SA 15s. They still amaze me. They hit the lows flawlessly and even perform on the higher end. I have them in a sealed box because I don't have room for a ported box but they are still extremely loud and can be heard and felt from a good distance. I'm giving 1000 watts to each of them and they sound amazing. They blow my old alpine type rs away. Great for SPL and SQ.

  3. Amateurs Don't Know How To Install

    Posted by Car Audio Tech on 4th Mar 2015

    I see a couple people on here saying the SAs are garbage or can't handle power etc etc. Apparently they don't know how to build a box and tube it to the right hz. It's more to installing a subwoofer than just slapping it in a box and throwing an amp on it. You can't expect it to perform optimally under those conditions. Do some research, if you can't install it right get someone else to do it. You are bashing an excellent product that you didn't do your due diligence on for it to function properly.

    I have 1 SA 15 dual 2 ohm that I replaced a kicker cvr 15 dual 2 ohm. The SA slams ridiculously. I am getting roof flex and I am wired @ 1 ohm. Box is 5.4 cubes tuned to 32 hz. I will be getting a nightshade next.

    I am Happy With The Product. I am Glad You Guys Place A Second Box.Pluse Extra Protection Inside The Box.The Outer Box Was Damage. But The Speaker Was Fine.I Can Expect That From U.P.S.But Thanks Again.

  5. Fist Time Having Music

    I am Happy With The Product. It's Been A While To Receive It But I Understand The Reason For The Setback.

  6. Pounds.

  7. don't bash sundown

    Posted by Unknown on 20th Feb 2014

    To the kid who is bashing the Sa's. I'll have you know I have 1 sa 15 d2 in a 5.1 cubic foot box tuned to 36 hertz. On a hifonics brutus 1600 at 1 ohm. I have embarrassed cvrs, solo barics, cvxs, and even solo xs, and did I mention my single 15 does 148.2 on the dash sealed up sundown is on a much higher level than kicker will ever be. Sundown has the trophies to prove it bud.

  8. BEAST

    Posted by James on 4th Oct 2013

    I currently own 8 sa 15 d2's 6 in a 1986 chevy blazer with a 4th order and the 2 other's in a 2002 Mitsubishi eclipse walled 4th order these subs are amazing and clean current have a hifonic's 2400d in the eclipse at 1ohm and the subs love every watt of power!! currently no amp in the chevy i had no problem with ssa in anyway shipping was fast and cant beat the price of these beasts! the chevy blazer will soon have a sundown 5000d and the eclipse with a sundown 3500d v.2

  9. You got to be kidding me

    Posted by daddiescaddy on 30th Jul 2013

    I recently purchased 2 sa 15 dual 2. They are replacing kicker cvr 07 154. The box is the same and amp which is a kicker zr1000 tuned for deep bass. The gain on amp is quarter turn back from half and these subs are garbage compared to kicker. My car was micked at 147 dbs wit the kickers. These subs can't take a pounding like u guys are saying in these blogs. To make a long story short sundown entry-level subs are no way in the same league as kicker comps.

  10. 900 watts rms

    Posted by Bobby Cruz on 25th Apr 2013

    this sub is good and at a affordabale price. i own 2 of these and 900 watts rms on each sub. they can handle the beating

  11. decent

    Posted by John on 26th Jan 2013

    This sub is decent and can handle power but tends to sound peaky with a lot of notes at 600 to 1000 rms there is a lot better options out there i just purchased 2 AUDIOBAHN AW1200J subs after owning one of these and I can say in my opinion the audiobahns destroy one these and then some and these subs are overrated yea they handle 1000 rms but sound like shit doing it.

  12. pounds

    Posted by Unknown on 3rd Jan 2013

    feeding it a 1000 rms and slams no prob very rarely gets hot even overpowering it and picks up lots of notes especially for a 15 picks up notes most 15s wouldnt

  13. Great

    Posted by Ricky on 24th Nov 2012

    Bought one of the sa dual 4 ohm 15 to replace 2 ma audio hk 12's i had and it puts to shame in loudness and sound quality. Rated at 600rms im currently feeding it 1000 rms out preforms two subs supposedly rated at 1500 rms each. Also cost the same price per sub give or take a few dollars depending where you get them and weighs about a half the weight.

  14. Sundown won me over

    Posted by Trevor Kountry Boyz/Kountry Divaz Founder/CEO on 27th Oct 2012

    I love the sound quality from sundown. One of my best friends has 8 sundown 12's and he convinced me to convert to sundown and i am very thankful. Im giving one sa-15 atleast 3000 watts and its asking for more. Im getting my other sa in a couple of days. I appreciate all the help from Sound solutions audio I will be buying from here again very soon. I also own 2 car and truck clubs and we will be using ssa from now on. Thanks

  15. Amazing Subs

    Posted by Unknown on 16th Sep 2012

    i bought two of the sundown Sa15s , everyone was saying they were amazing but had no idea what to expect, once i got them in my truck , they sound truly amazing and its laughing at the 1500rms im giving it , easily can handle double or triple its rated power, best sub for the money hands down.

  16. sa-15 ftw!

    Posted by supa's mom on 6th Jul 2012

    ran different subs and in this price range produces the numbers i want while sounding great!

  17. made my girlfriend go into labor

    Posted by N/A on 6th Jul 2012

    these subs bump like crazy i was goin down the freeway playing some DJ Billy Meade and had to pull over cause my gf startin giving birth in the backseat (no ugly bitches ride shotgun in my car)

  18. gave me a eargasmn

    Posted by steve mead on 6th Jul 2012

    more of a orgasm than supa's mom did

  19. Worth every penny

    Posted by Jk on 6th Jul 2012

    This sa 15 is bad to the bone blows away any pair of 12's I've ever had & its not even broke in yet. Its louder & produces clean low ass bass. A pair of Sony,kicker cvr,orion xtrs,or Jl w3 12's have no chance.

  20. Solid sub

    Posted by N/A on 5th Jul 2012

    I have one of these in a POS ply wood box 3cubic feet tuned some where around 32 hertz and it pounds! I've seen people say that sundown subs dont handle lows well, but i don't think any of those people have ever herd a sundown product. Even in my cruddy box this subs destroys the lows. Its currently getting about 1000watts rms off a 1700 watt brutus amp and it has no problems handling almost double its rms. Great product end of story.... cant wait for a X line to come out!

** T/S Specifications measured with coils in series

The Sundown SA series has been our most popular product line since the introduction of the SA-12 in 2009. It was the result of over a year of testing and prototyping until all of our goals and expectations were blown away. The SA series has continually evolved over the years thanks to extensive testing and feedback from our SPL competition Team and our customers but still stays true to its legendary design heritage. It has never failed to prove itself year-in and year-out in every application ranging from daily musical builds to all-out SPL competition vehicles.

When designing the SA series we started out with an FEA optimized motor & coil design capable of 19mm of one-way Klippel verified excursion and just over 33mm of x-mech. This motor & coil setup was then mated up to an extremely robust double-layer Nomex spider with fully tied-on “XL” tinsel leads (84-Strands of Conductor), an SPL competition grade paper cone, and a strong foam surround. The motor also features a large magnet ID shorting ring (faraday ring) to reduce distortion causes by inductance & inductance variation over stroke.

We realized that this still was not enough to meet our goal of delivering the best driver on market in this price range to our customers. To that end we designed a highly optimized voice coil cooling system that has since found its way into almost every other subwoofer we make to this day. This system allows our 2.5" coil to match and exceed the thermal performance of many competing 3" coil drivers on the market without requiring the usage of a much heavier voice coil than required for the design. The result is that the SA features the ideal mix of mass & stiffness to give you the best performance in nearly every type of enclosure.All of this hard work and engineering has led to the incredible reputation now enjoyed by the SA series worldwide. We are very proud of what these woofers are capable of and we believe that they are one of the best woofers on the market today hands down for the money.
