Featuring advanced cooling technology, a robust cast aluminum frame, and precision-engineered motor design, it offers exceptional bass clarity and durability. Perfectly optimized for ported enclosures, this subwoofer is a top-tier choice for car audio enthusiasts seeking powerful, reliable low-end impact. ## 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.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Sound quality πŸ‘Œ *by A***M on 12 December 2025* Good bang for the buck, hits strong with the proper tune and box fitment is great with the box I've chosen ### ⭐⭐⭐⭐⭐ no issues *by D***N on 18 June 2025* great packaging, no issues ### ⭐⭐⭐⭐ Muy bueno *by E***A on 7 October 2023* El subwoofer es muy bueno,lΓ‘stima que la marca no incluye un manual con las especificaciones ni una calcomania ni nada solo el woofer y se acabo,deberΓ­an considerarlo, ## Frequently Bought Together - Sundown Audio SA-8 V.3 D4 8" 500W RMS Dual 4-Ohm SA Series Subwoofer - AudioControl EPICENTER Digital Bass Restoration Control Processor, Car Audio Bass Booster Enhancer with Wired Remote Control (Black) - SFB-1000D - Sundown Audio Monoblock 1410w RMS Amplifier --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/444292028-sundown-audio-sa-8-v-3-d4-8-500w-rms](https://www.desertcart.tn/products/444292028-sundown-audio-sa-8-v-3-d4-8-500w-rms) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-23*
