    Power Specifications - Full Range Channels

    RMS Power @ 4 ohms

    The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far.

    If the final impedance of your speakers or subwoofers equals 4 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound.

    50 watts x 4 channels
    RMS Power @ 2 ohms

    The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far.

    If the final impedance of your speakers or subwoofers equals 2 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound.

    100 watts x 4 channels

    Amplifier Specifications

    Amplifier Series
    This designates the series of the amplifier. Many amps are available in a litany of different wattage and channel configurations, but maintain consistent features throughout the product line.
    Riot (Boss)
    Amplifier Class

    An amplifier increases the power of the signal being fed to it by taking energy from its power supply and matching the signal but increasing its amplitude. Amplifiers use many different methods for converting these electrical signals and have been categorized into classes.

    Class A/B: Greater than 50% of the input signal is amplified while the other percentage is “off”. These amplifiers have a small amount of current flowing through the output transistors all the time which almost eliminates crossover distortion. Class A/B has great sound quality but is not as efficient as class D. These amps are most commonly used to drive speakers.

    Class D: Also known as switching amplifiers, class D amps have output transistors that are completely turned “on” or “off”. This means that when the transistors are on, there is almost no voltage across them but when they are off there is significant voltage but no current flowing through it which makes these amplifiers very efficient at the cost of sound quality. These amps are most commonly used to drive subwoofers.

    Other Classes: You may see classes such as GH, bD, X, FD, etc. by some manufactures. These amplifiers tend to be either class A/B, D or a hybrid of the two but with improvements to their designs that can make them more efficient or offer better sound quality.

    AB
    Number of Channels
    Each channel on an amplifier will power one speaker using a positive and negative cable. There are various types of amplifiers, each designed to power a certain number of speakers. Monoblock amplifiers, also known as single channel, are designed to power one or more subwoofers. These amplifiers often have very high power ratings. On the other hand, multi-channel amplifiers power multiple speakers, usually at lower power ratings. 2-Channel and 4-Channel amplifiers can power car speakers or low powered subwoofers. Occasionally you might see a 5 or 6-channel amplifier that can power speakers and subwoofers at the same time. The most common setup is a monoblock amp to run subwoofers and a 4-channel amp to run door speakers. Check out our Knowledge Base for more information.
    4
    Total Peak Power Output
    The total peak power output is measured as the wattage per channel multiplied by the number of channels, and is calculated at the lowest level of operating impedance.

    It is measured during a brief musical burst, such as a sudden drum accent. Some manufacturers display peak power ratings on the face of their products to increase the appeal.

    The RMS power rating is more accurate, and we recommend using it for product comparison.

    400 watts
    Maximum Input Gauge Size
    This is the largest gauge wire that will fit into the power and ground terminals of this device. The lower the gauge number, the thicker the wire is. For example, a 4 gauge wire is thicker than an 8 gauge wire and thus has higher current carrying capacity. Always do your best to get this size wire to reduce the risk of damage to your components.
    8 AWG
    Minimum Impedance Unbridged
    The lowest impedance the amplifier will handle when it is not bridged.
    2 ohms
    THD at Rated RMS Power
    The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
    0.01%
    Speaker Level Inputs
    Speaker level inputs are commonly referred to as high-level inputs and vice versa. This input type allows you to get your audio signal directly from the speaker wire in your vehicle, instead of using RCA cables. The advantage of this is factory integration, as most stock radios do not have RCA outputs to run amplifiers.
    Yes
    Signal-to-Noise Ratio
    This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
    90 dB
    Fan Cooled
    A great feature to have if an amp generates a large amount of heat. Cooling fans can help regulate the temperature to prevent the amp from overheating (burning).
    No
    CEA-2006 Compliant
    Amplifiers that have been tested to meet specific standards. When a car amplifier meets these standards, you can be sure that it will be able to produce the amount of power specified by the official CEA-2006 rating. Usually, these rating consist of the following items:
    • RMS Power
    • Signal-to-Noise Ratio

    This rating applies to both external car amplifiers, as well as the amplifiers inside of in-dash stereos.

    Yes
    Hi-Res Audio Compatible
    This feature refers to if the product is capable of Hi-Res Audio (HRA) playback.

    can a boss R1004 4-channel amp be bridged to run a sub woofer ?
    joeetue on Jan 21, 2015
    Best Answer: Hello,

    In addition to what Dustin has outlined, we want to add that the manufacture does NOT specifications/figures for If you do bridge a given set of channels. This implies that it is NOT recommended to do so.

    Why is their no warranty option for this amplifier?
    A shopper on Jan 9, 2015
    Best Answer: Hello,

    SquareTrade categorizes their warranty options by the value of the product. The lowest possible warranty option , for Consumer Electronics, is between $40 and $49.99 . With that said, there isn't an option available through SquareTrade for coverage on a product less than $40, unfortunately. Therefore, the Boss R1004 will only have its 1yr Manufacture's Warranty available to it.
