## Description

Product Description Boss Audio R1100M RIOT 1100 Watts, Monoblock Power Amplifier, Remote Subwoofer Level Control Features Metal-Oxide-Semiconductor Field-Effect Transistor is a transistor used for amplifying or switching electronic signals. 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. Box Contains 1 X RIOT 1100 Watts, Monoblock Power Amplifier, Remote Subwoofer Level Control

Review: Quality product + brilliant sound (R1600 sent as replacement) - I purchased the R1100 last week and about half an hour later was emailed to say they did not have it in stock but could send the R1600 for no extra charge. So although i cant speak for the quality of the R1100, i can give a shining review for the R1600. Package arrived earlier than expected and immediately on opening it you could tell it was well made. Its currently hooked up to a single 400w 4ohm sub and it sounds fantastic (RMS of the amp is 350/4ohm). The remote input thingy is also really useful so you're not constantly deafening yourself. Hopefully it's durable enough to last a few years but so far I've been nothing but impressed.

**Q: what is the RMS off this amp? it only quotes the peak power of 1100w**
A: Do a search for this amp on Youtube, there is video which shows this amp only realistically puts out around 110 to 150w rms

**Q: Can it be used in car?**
A: Yes it's to power a subwoofer. Your I fotainment unit plugs into it via rca connectors

*by C***J on 22 August 2024*

I've put up a review because I'm unhappy with Amazon. I can not as yet use the Boss Amp because I don't have a 5pin connector for the audio in. It's not the most common of plugs and I assumed it would be with the amp. So the amp is all fitted and wired up except for the sound in. I contacted Amazon to ask if it was possible to speak to the seller of the Amp to ask if they can supply or where to go to get hold of a suitable connector but, well...... I'm writing this because I am currently no better off than before even though I did try chat help. No plug, no working amp. I have to now go searching www to find something and hope that it is the correct connector. I have tried BOSS direct - who were closed apparently, on a Thursday afternoon!
