Is it only inputting one channel (left or right), or summing them?** A: The system is just giving you a mono signal the subwoofer output on your receiver is just a mono signal unless you have a right and left output. I have never heard of right and left output before for a subwoofer, but I guess there is always a possibility. **Q: Is this a good choice for a center channel speaker?** A: It may work for you, depending on your speaker, the amp on other speakers, the other speakers, your set up (assuming you have something to feed a distinct center channel) and your room. I wouldn't. How many volume controls do you want to get up and mess with? If you're trying for a home theater setup, you'll be happier with Amazon's entry level Onkyo 5.2 system at $329. Use the speakers you have and upgrade as you can afford. On the other hand if this is a dorm room, go for it. **Q: I have a powered subwoofer but need to combine left and right channels with a cross. will this conflict with my powered sub?** A: probably not a good fit with a powered sub unless you are replacing the amp in that sub. **Q: can it handle a 12 inch sub 200watts?** A: It can drive the speaker, but how well will depend on the efficiency of the speaker and not just the size and watts it can handle. ## Frequently Bought Together - Douk Audio G4 Subwoofer Full-Frequency Mono Channel Digital Power Amplifier 100W - FosPower Banana Plugs 2 Pairs / 4 pcs, Closed Screw 24K Gold Plated Banana Speaker Plug Connectors for Speaker Wire, Wall Plate, Home Theater, Audio/Video Receiver, Amplifiers and Sound Systems - Amazon Basics Speaker Cable, Easy Assembly, 16-Gauge, Bronze, 100 ft --- ## 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.hu/products/174949513-douk-audio-g4-subwoofer-full-frequency-mono-channel-digital-power](https://www.desertcart.hu/products/174949513-douk-audio-g4-subwoofer-full-frequency-mono-channel-digital-power) --- *Product available on Desertcart Hungary* *Store origin: HU* *Last updated: 2026-07-27*
