    Default Cant decide which amp to get...Plz help

    So this is pry a silly question but i have a RF P3 D212 and need an amp for it. Im semi broke so the cheaper the better. Im stuck on these 3.

    1. http://www.katerno.com/detail/s/7276...eus-Amplifier-

    2. http://www.millionbuyplus.com/view_p...emno=HIFBXI610

    3. http://www.hifisoundconnection.com/S...47240251244237

    Is it smart to go 1000 watt rms for the p3? Ill possibly be adding another sub latter... Another question i have is whats the difference between the class's of amps? Example class a, b, d etc.
    Thanx,
    -Jason

    The first one looks good, but it's class A/B which means it will draw a LOT of power.

    The different classes are the type of amplifier it uses. A is generally regarded as the cleanest, but also the most inefficient. It will use a ton of power. B is almost never found by itself, usually in a hybrid with A - A/B. A/B is very clean and a little more efficient. These are "high current" amplifiers that are very powerful.

    Class D is the most efficient generally speaking, usually made for subwoofers because the distortion created by class D is outside the frequency range of subwoofers. These will draw less power for a given amount of wattage.'

    P.S. - Why did you start two threads with the same basic question?

    Too much power won't hurt it as much as too little power.

    Good point on RF's reccomendation. I wasnt sure about the whole ported thing cause of that. My buddy was tellin me that ported are always better but i see now after researching that not always the case.
