    Enough power for a jl 12w3v3-4?

    Im adding 1 12" jl 12w3, will an alpine mrp m500 have enough power so the sub is not underpowered? I can just get the 4 ohm JL and run it at 2ohm and get 500 rms correct?

    Stats:

    Mono subwoofer car amplifier
    300 watts RMS x 1 at 4 ohms (500 watts RMS x 1 at 2 ohms)
    Variable low-pass filter (50-200 Hz, 24 dB/octave)
    Variable bass boost (0-12 dB at 50 Hz)
    Subsonic filter (15 Hz, 24 dB/octave)
    Class D amp with MOSFET power supply
    CEA-2006 compliant
    STAR Topology (minimizes internal noise and prevents ground interference)
    Speaker- and preamp-level inputs
    Gold-plated screw terminals
    Fuse rating: 30A x 2
    8-gauge power and ground leads recommended wiring and hardware not included with amplifier
    10-6/8"W x 2-1/2"H x 9-5/8"D

    You cannot underpower a sub. 500 should be decent, and get 4 gauge wire. If its a single 4 ohm voice coil woofer you cant make it 2 ohm, you will need a dual 4 ohm.

    If its a single 2 ohm voice coil then yes. Id go with dual though, because you may change things out over time or add another one so your options will be greater with the different wiring ability's. But its also easier to go with a single voice coil.

    i ran one off the mrp m400 and it was fine, id say go 4 gauge since you might want to upgrade in the future.

    ok so should I get the 2ohm version and use the mrp m500 amp? what would be the point of getting the single coil 4ohm sub instead?

    Ok do you think the type R would fit in my box?

    12" subwoofer with dual 2-ohm voice coils
    Kevlar® reinforced pulp cone with Santoprene™ rubber surround
    cast aluminum frame with perimeter venting
    frequency response: 23-500 Hz
    power handling: 200-500 watts RMS (250 watts per coil)
    peak power: 1,500 watts
    sensitivity: 85 dB
    top-mount depth: 7-5/8"
    sealed box volume: 0.57-1.0 cu. ft.
    ported box volume: 0.75-2.0 cu. ft.


    Box specs:

    It is 8.25 inches deep, 11 1/8 inches around cutout and 1.2 cubic feet.

    would the type r be too close to the back of the box?
