Incredible. Before I give the details of the sound I will mention that I have my Big 3 and a HO alternator. Originally I had the SA 18 a couple years back. Due to personal reason I had to sell it. That was my first Sundown sub and it made me a fan for life. Unfortunately I downsized vehicles so I couldn't fit an 18 when I was back in the market for one. I decided to go with one 12 to save space. While the SA 12 is not as loud as the SA 18, it does sound more accurate and cleaner. This sub sounded great before my Big 3 and HO alternator, and sounds even better with them. I bought a prefabbed enclosure here from Amazon, (MSW Enclosures) @ 2.0 Cu. Ft. @ 32hz. I have an Infinity K.1000 powering it and this little monster hits amazing. The lows flex my car like no other. Though most people say this subwoofer is for SPL I would have to disagree. I'm a fan of most genres and it never disappoints on the performance. I've noticed a little more output since I've been playing it more, but I wouldn't be scared to push these hard right out of the box. Don't cheap out on your amp and box, and you'll be plenty satisfied. This is a great subwoofer and I can't wait to add a second one. ... show more

  • Best 12" sub I've ever owned.
Let me just start by saying that I've literally spent hours researching subs by reading all the reviews on amazon and going through countless forums. Seriously it took weeks to go through all the info. My price tag for a sub was $200 so I wanted the best in that category. All signs pointed to Sundowns SA-12. I bought a ported box that fell within the specs for this sub and have an amp that can provide 700 watts rms. In comparison to other single 12" set ups I've had, (which for the most part have been infinity kappa perfects and a kenwood) this SA-12 is like having two of those infinity's. For the people worried about SQ, even in a ported box it is extremely clean, extremely loud, and hits extremely low. My box is 2 cu ft before displacement and is tuned to 33hz. Which is very close to the recommended box specs for this sub. The sub is heavy, well constructed, and packed very nicely to protect it during shipping. If you're a person that is partial to a certain name brand, just do a google search for sundown SA-12 versus whatever name brand you want to compare it to and I promise someone has asked the same question and see for yourself. It's usually sundown all the way. I read about people with two of these in their trunk and I can't imagine how they keep their car from falling apart. I promise if you put this thing in the right ported box (do your homework) and have an amp that can produce an actual 600 or more rms you will see exactly what I'm saying. I just wish I could give this thing six stars. ... show more

  • Great bang for the buck
Great sub, only running about 450W to it right now and it hits very very hard, very clear. Looks well built, and it's HEAVY. Bass got louder/deeper after using for a few weeks. I see a lot of people running these at 1100W daily with no issues, they can take a beating. I've had kicker / alpine / few other brands and this Sundown hands down is the best in the price range. EDIT: Had to send my sub in for repair. Customer support from the seller WoofersInc and Sundown themselves was very fast, process was easy and support was very helpful. Cause of an unwound voice coil was most likely distortion. Please tune your amp/head unit properly! ... show more
