    AMP Spec Confusion

    Here is a spec of an amp. Cam someone help me translate this information into something more understandable :shock:
    ----------------------------------------------------------------------------------
    Description

    MAX Power: 100Wx4 (4Ohm Stereo), 250Wx2 (Bridged 4Ohm)
    RMS Continuous Power (Watt) at 12.0V
    4Ohm Stereo 35Wx4
    2Ohm Stereo 45Wx4
    Bridged 4Ohm 90Wx2
    RMS Continuous Power (Watt) at 14.4V
    4Ohm Stereo 55Wx4
    2Ohm Stereo 65Wx4
    Bridged 4Ohm 130Wx2
    ----------------------------------------------------------------------------------

    So if this amp is bridged for two subs, would it be 250Wx2 or 130Wx2 or 90Wx2 :?: :?: :?:

    Why is there 3 different power ratings :?: :?: :?:

    Disregard anything that says Max. Generally with the car running the astra pushes out approx 14.0V constantly.

    How much the amp will push out depends on the Amp and how good it is. Certain manufacturers quote less than the amps push out e.g. Soundstream, Genesis, DLS PG but as a general and safe rule I would stick to the 12V figures, so 90WX2 RMS.

    Why is there 3 different power ratings
    Well quoting max or PMPO makes the amp sound very good to the lay person and probably sells them a few more amps than they would if they quoted 4X35w. Quoting 12V and 14,4V is kind of a norm, well 12V needs to be quoted if the amp is to pass any standards rating of any kind (CE and such) and 14.4V is quoted as this is generally the max ceilling that you will get in a Car, unless of course you purposely run it higher for SPL purposes.

    depends what sub your running mate. different subs have different connections, so they run at different impedances. whats your sub and we'll tell ya whether its suitable or not.

    im assuming your running a standard 12v battery supply? (if you dont know then you will be)
