Sundown Audio SA-12 D4 CLASSIC 12" 750W SA Series Subwoofer
Features & Specifications:
The SA series was designed to be an excellent sounding sub woofer that is equally at home sealed or ported. We feel that the SA series is one of the best woofers available in it's price category and will satisfy the needs of a wide variety of users ranging from bass-heads to audiophiles!
The SA line was designed to be the centerpiece of the Sundown Audio sub woofer lineup -- the line to which all of their other lines are compared. They started with an FEA optimized motor design capable of 19mm of one-way Klippel verified excursion and significantly more x-mech (maximum mechanical excursion). This motor was mated to a top quality double layer nomex spider, an SPL competition grade paper cone, and a strong foam surround capable of handling the excursion and force generated by the motor structure. The motor also features dual Faraday rings (shorting rings) to reduce inductive distortion. At Sundown Audio this still was not enough so they designed a highly optimized voice coil cooling system that ensures that an SA series woofer will never over-heat when used anywhere close to it's rated power level. This system allows the 2.5" coil to match and exceed the thermal performance of many 3" coil drivers on the market today.
The SA series is also gaining popularity in SPL competitions due to their excellent voice coil cooling and rugged, durable construction with several customers achieving output well over 150 dB!

FAQ
We always reccomend a big 3 kit for every vehicle, regardless of the system. However, if you plan on running more than 1,500 watts we reccomend a good AGM battery underhood, and then from there more power will need more electrical upgrades depending on power.
