## Overview

## Description

The SA line was designed to be the centerpiece of the Sundown Audio subwoofer 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 we 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 our 2.5" coil to match and exceed the thermal performance of many 3" coil drivers on the market today. This same voice coil cooling system has been applied to all of our larger woofers lines as well due to it's proven effectiveness over the years in the SA series. All of this hard work and engineering has lead 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 in their price and power range.

## Questions & Answers

**Q: Will someone tell me if rockford fosgate prime 500 whould it be a match for this sub**
A: The amp you mention has this spec:Number of Channels:	1Rated Power (RMS Continuous Power):	320 Watts x 1 @ 4-Ohm 500 Watts x 1 @ 2-OhmThe speaker is dual 4 Ohm, so it can be wired to 2 ohm to enjoy 500W.

**Q: Would 2 of these work under the rear seat of a 2011 Silverado extended cab and what amp would be best to run 2 of these?**
A: I’ve got one under the rear seat of my 07 Silverado on a 750 watt Rockford Fosgate amp and it beats pretty good. No doubt 2 of them on an adequate sized amp would be killer.

**Q: Im running two sa8v2s on my dd m1c and love them but i want one more for a total of 3. I can't find the v2s, anyone know where i can find one?**
A: On ebay or sundown audio website.

**Q: What are ther terminal sizes?**
A: Dont matter. wire it to 2 ohms and pair it with another one. Dont get a single 8. Trust me. Pair it. I have 2 sa 8s. My opinion is get a sa single 12. Sounds better than 2 8s. Dont waste your money.
