We use it in billions of them. In our computers, our telephones, game consoles, cars, electrical appliances and in this case, our Amplifiers. They are found in systems where information is processed or stored. A MOSFET is basically an electrical switch that allows the flow of electrical current. An electrical switch has two possible states, ON or OFF. This is where the MOSFET performs its most important role in our D Class amplifiers by allowing or preventing the flow of power and creating an efficient amplifier. And of course, Monoblock means that there is only one channel being offered. Monoblock and class D amplifiers are typically more efficient than multi-channel or class A/B amplifiers because they draw less current from the battery. With a Full Range amplifier you not only have the option to run your speakers, but also your subwoofers. By just a flip of a switch from Low to Full, the CE102 will change from offering the "Low" that you need for a subwoofer application to a complete range of frequencies to be able to listen to your 2/3/4 or 5-way speakers. The CE102 has two different ways that you can get a signal into it. One is called Low level input and the other is called High level input. A low level input is measured in voltages. It comes in the form of RCA outputs from the back of your receiver and goes to the RCA inputs on your amplifier. A high level input is measure in wattages. It comes in the form one positive and one negative wire from the back of your receiver to and goes to the input terminal of your amplifier in the same wire form. Low-level (RCA) input wiring is preferred for best audio performance. Always use a high-quality RCA cable for best audio performance. Do not connect BOTH the high level and low level inputs from your receiver to your amplifier at the same time! Speakers reproduce sound based on high, low or mid-range frequencies. High pass crossovers are geared specifically towards "highs" such as all size speakers, mid ranges and tweeters. Subwoofers also reproduce sound based on a number of different low-range frequencies. This process is called the crossover effect and occurs because the vast majority of audio systems cannot cover the entire spectrum sufficiently to minimize sound distortion and maintain an appropriate frequency ratio. Unlike the "Variable High and Low Pass Crossover" offered on our other amplifiers, you are not able to set exact sound specifications such as the bass, mid-range and high frequency reproduction. This High And Low Pass Crossover is fixed.

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.vn/products/52181521-r1004-riot-series-4-channel-amplifier-car-audio-class-b](https://www.desertcart.vn/products/52181521-r1004-riot-series-4-channel-amplifier-car-audio-class-b) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-23*
