    Default PA1100.5 RMS power question.

    Hi, I have a question about the PA1100.5 RMS power.
    According to the Polk Audio website, the power is:
    125 watts x 4 (2 ohm) and 600 x 1 (1 ohm) continuous power;
    250 x 4 (2 ohm) and 1200 x 1 (1 ohm)

    The speakers on my car are:
    Front: Polk Audio db6750, 4 Ohms,
    Rear: JBL P9633, 4 Ohms,
    Subwoofer: RockFord Power T112D4, 2 Ohms,

    Can I use the PA1100.5 on my car?
    And what will be the RMS power output?
    Thanks for any help.

    For example, if we look at the sine wave voltage at the output terminals of a power amplifier, we will find the RMS voltage to be the peak voltage (Epeak) divided by the square root of 2. If we measure the RMS sine wave current from the amplifier, we will see that, similarly, it is the peak current (Ipeak) divided by the square root of 2.

    Multiplying the two, we get:

    (E peak /(sq root 2)) * (I peak /(sq root 2)) = (E peak * I peak)/2

    boy does that sound like a rip off..

    i 4get what jvc said but if u look at the amps specificatioons on website it states 80w at 4ohms, so interiors r getting at least 80w a piece(meaning i'd b pretty careful setting those gains) sub it doesn't mention 2 ohms but if 1 ohm is 600, i'm betting 2ohms is about 3 or 400
