Has 2 set of connections middle says 1 ohm like you can bridge. Tried to do setup can someone guide to setup clean** A: The amp said 1 ohm and that 1 ohm is the whole 750 watts so just follow the wiring directions on your subwoofers jow you get 1 ohm is how you wire your subwoofers and yes you have bridge the connectors, but if you don't connect the subwoofer as directed you will blow up your subwoofers or burn your amp. It depend on how many voce coil each of your subwoofers had if each has 2 pairs of voice coil than that is called (DVC) dual voice coil so you have hook them up in series if it only had 1 pair on each subwoofer than it's called (SVC) single voice coil and you can hook it up like a normal 2 channel amp, but your subwoofers RMS rating has to be more than 300 watts per sub for it to handle the 750 watt amp. The can be use as 1 ohm, 2 ohms, 4 ohms or 8 ohms , but that's just depends how you bridge the voice coils on your subwoofers. Remember the lower the ohms the bigger the watts and the higher the ohms the lower the watts so connect your subwoofers as directed some subwoofers such as Rockford Fosgate does come with a schematic of how to hook up the subwoofer, but if yours doesn't you can always go online to get it. **Q: Why the amp doesn't work when its cold outside?** A: This is the first time I’ve have ever heard of an app not working because it’s cold. Recheck all connections If all of them are good you have a bad amp. **Q: Can this power 2 kicker 10s 2ohms ?** A: Depends on the RMS power of the woofers. I ran with 2 10S of ROCKFORD FOSGATES and the RMS is 200 watts per woofer and I ran with 4 ohms and it can pump some good bass if you're not a bassholic like me I just like my bass flows along with the music. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by S***S on 26 February 2026* Would recommend ### ⭐⭐⭐⭐⭐ Review *by C***H on 7 April 2025* The product came fast and was well worth the money ### ⭐⭐⭐⭐⭐ Review *by R***E on 7 November 2025* Although prime is their budget line of products, RF doesn’t make junk! I have this connected to two 2 ohm subs in parallel making it 1 ohm circuit. It still produces more than enough power to over excursion if needed! RF in my opinion is the BEST there is. They work flawlessly, they last longer than I can determine and they make subs pound hard. ## Frequently Bought Together - Rockford Fosgate R2-750X1 Prime 750-Watt Mono Amplifier - Rockford Fosgate P3-1X12 Punch Single 12" Loaded Subwoofer in Ported/Vented Enclosure - Rockford RFK4X 4 AWG Complete Amplifier Install Kit --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/353921803-r2-750x1-750-watt-mono-amplifier](https://www.desertcart.co.th/products/353921803-r2-750x1-750-watt-mono-amplifier) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-24*
