I got my Sundown SA-12D2 a couple of days ago. Unfornately I was too illl to installl it. Out of the box I was totally impressed with this driver considering how much it cost. The motor is too big to be rated at 600 rms. Anyway I swapped out my RE Audio SXX and dropped the SA in. The enclosure is 2^3 tuned at 32 hz. I found what I was looking for as far as sound quality. This driver has more of a musical quality to it than the SXX. It seemed like the SXX just wanted murder lows. This sub gives me the best of both worlds. It can kill the lows and still give you good quality lower mid bass. I'm running it on a RF Power T500-1bd that came rated at 762 watts @ 1 ohm. When I get better I'm purchasing 2 of the 15's for my Explorer. I wanna thank every one that post helpful information on this forum also.

hell yea! i liked my sa-12 also. very musical subwoofer IMO. made everything sound cleaner than a Treo sub i was using before it. Only problem I had is i want 2 of them now, 1 isnt enough.

My SXX played the lowes better than the SA but the SA just to me sounds better overall. Especially for the price. I just wanted a 1 subwoofer system for my Altima. Plus I wanted a sub that I could use in a ported or sealed box depended on my mood. SXX is strictley ported. Plus the SA is just plain loud compared the SXX.

Nice buy. Pics of install are a must, you know?

Sorry, wifey and the kids are out bumping it right now. When they get back I'll get some picks.

Great to hear you are happy. Running a couple of the SA8's and love them.

Waitin' on some pics!!

Yeah it seems like a lot of people are using SA-8's. For the prices Sundown is charging for this line it has to be 1 of the best bang for your buck deals out there. I also like how it seems Jacob is so hands on all of his products and is always conversing with his customer base. You don't see that from a lot of manufactures. He is constantly on Facebook. I'm officially a Sundown fan. Now I have to figure out how to get the money together for one his amps.
