    for "good listening" i would not push it with anything less than an amp which is rated at the following at 12.5 volts to 13.5 volts...

    rms - 450
    thd - less than 1% (preferably less than 0.5% but nobody's perfect).
    12 or 18 db per octave variable low pass crossover.

    somesort of bass boost -- ideally you wont use it, but people always end up needing 3 - 6 db of boost at 40 hertz. dont go craking it up to 18 (on some amps) and getting ridiculous though.

    suggested amps...

    coustic (unsure of model, btu they've got a 600 x 1) (bridged)
    mtx 8302 (445 x 1) bridged
    cadence Z8000 (500 x 1) bridged

    other --
    fosgate / usamps / zapco but the latter two are pricey... the cadence or the mtx ought to do u fine.
