    Depends on the enclosure...don't look at what the lowest frequency response number that is stated in the specs cuz that don't mean sh!t.

    you dont need any more crossovers if your amps have all those filters.

    HPF means high pass cross over.

    LPF= low pass crossover

    hey pedro
    umm
    would it be bad to push 480rms in my 500rms sub with that profile amp that dan has?
    or shuld i just stick with a 400rms boss amp to keep it safe?

    480 will be fine.but.......is that at 4 ohm mono or 2 ohm mono?

    ok first set the sub amps crossover to ON.then try the setting just before the 90hz setting

    then set the other amps crossover to HPF.then turn the dial till it sounds good to you.just enough midbass not too much bass.

    okk...the profile one is for the speakers and the power acoustik is for the subs....so the profile one does not have an hpf filter so that means i need to get one right?
