Now with that being said your 10" sub will not handle 2200w it will only handle very short peaks of 2200w and it would have to be clean wattage. this amp will push it well set it about 3/4 and X it over at about 90hz **Q: Can you support two 10" subs with this one amp?** A: Hello. Yes, this amplifier will support two subwoofers. You will need to make sure that each subwoofer does not exceed 400 watts peak power. **Q: will this amp power 2 6x9 500 watt door speakers and 2 rear pillar speakers?** A: It will with ok sound quality if it's for inside the car listening pleasures. However getting another one and bridging it or a higher powered amp for a good baseline would be recommended. ## Frequently Bought Together - BOSS Audio Systems R1004 Riot Series 4 Channel Amplifier Car Audio - Class A/B, 400 High Output, 2-8 Ohm Stable, High/Low Level Inputs, Full Range - BOSS Audio Systems KIT2 8 Gauge Complete Car Amplifier Installation Wiring Kit with Power Cables, Ground Cables, Turn-On Wire, Speaker Wire, Terminals - BOSS Audio Systems CH6530 Chaos Series 6.5 Inch Car Door Speakers - 300 Watts (Pair), 3 Way, Full Range, Tweeters, Coaxial, Sold in Pairs --- ## 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.gr/products/157868702-audio-systems-r1004-riot-series-4-channel-amplifier-car-audio](https://www.desertcart.gr/products/157868702-audio-systems-r1004-riot-series-4-channel-amplifier-car-audio) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-10-25*
