Only has a single pair of terminals with the SSI selectable impedance switch, so I dunno how it could be DVC. I was hoping or dual 2ohm, so I could wire to 1ohm at the amp. Doesn't seem to be possible. Unless its internally wired for the selected Impedance (2ohm, or 4ohm), x 2 with only one set of terminals. I still don't see how that could be used to select parallel or series wiring. The manual is no help. **Q: Install Difficulty?** A: Same as any other sub but the switch to switch it from two homes to 4 ohms would be inside of the box **Q: Can this paired with the Kappa speakers fit in a 2011 Genesis Coupe?** A: Sorry, i could not confirm this for 11 Genesis but i suggest to download the full dimension from (crutchfield.com) item PDF manual or you can ask the tech directly over there... Hope this can help you.... ## Customer Reviews ### ā­ā­ā­ā­ā­ Great *by S***S on 27 January 2024* Great ### ā­ā­ā­ā­ā­ Small but powerful *by S***N on 30 June 2023* It produces surprisingly clean low bass. You can use 250 W @ 2Ī© RMS power, over than that it starts struggling. You need a small but strong and heavy enclosure otherwise enclosure can't hold the woofer load. ### ā­ā­ā­ā­ā­ Amazing bass and power handling *by A***. on 3 July 2023* One of best speaker I bought. Delivering excellent bass without any distortion at rated power. Fixed with crown CDI 4300 amplifier. ## Frequently Bought Together - Infinity Kappa 800W Subwoofer With Selectable 2 Or 4-Ohm Impedance, 8-Inch Size - Skar Audio SK1X8V Single 8" Universal Fit Ported Subwoofer Enclosure --- ## Why Shop on Desertcart? - šŸ›’ **Trusted by 1.3+ Million Shoppers** ā€” Serving international shoppers since 2016 - šŸŒ **Shop Globally** ā€” Access 737+ million products across 21 categories - šŸ’° **No Hidden Fees** ā€” All customs, duties, and taxes included in the price - šŸ”„ **15-Day Free Returns** ā€” Hassle-free returns (30 days for PRO members) - šŸ”’ **Secure Payments** ā€” Trusted payment options with buyer protection - ā­ **TrustPilot Rated 4.5/5** ā€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/259622139-infinity-kappa-800w-subwoofer-with-selectable-2-or-4-ohm](https://www.desertcart.co.uk/products/259622139-infinity-kappa-800w-subwoofer-with-selectable-2-or-4-ohm) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-16*
