    Default Looking for amp to power 10" L7 2 ohm DVC

    I'm looking to upgrade the stereo in our 02 Mobius LSV. I picked up a used Kicker 10" L7 but it is 2 Ohm DVC and now I'm looking for an amp to power it. Would I be better off bridging a 2 channel amp and run it at 4 Ohms? OR get a momo amp that is stable at 1 Ohms? I believe the L7 is looking for 600 watts RMS.

    Also, I'd like to stay at or below $200. Any thoughts?

    If the Sub is a 2ohm Duel Voice coil then in order to use it correctly it will be hooked up as 1ohm.

    Duel 4ohm DVC gets connected as a 2ohm load.

    The amp you select will have to be stable at 1ohm in your description.

    Wiring the two 2 ohm coils in series for a 4 ohm load is also correct. This would allow one to wire the sub on a 2chnl amp, providing it did low-pass. If doing a ported enclosure, make sure the amp has an adjustable subsonic. If not, then find out what its internal fixed subsonic is and tune accordingly. If sealed, then is really wont matter, unless its set way below what that 10" want to play, which is 24Hz for the L710. I would rather see mono amp run at 4 ohm as opposed to 1 ohm, to achieve the desired watts rms. Added head-room and a bit more efficient since it wouldn't be running peddle to the metal.

    A 4 ohm DVC can be a 2 or 8 ohm load at the amp.

    I think your $200 budget is going to make it real tough to find a quality amp, even used, thats going to give you 600W or more x 1 @ 4 ohm

    Spy60,
    You have several choices, two of which you already stated.
    1) A 1-ohm stable monoblock amplifier to drive dual 2-ohm voice coils in parallel for a net 1-ohm load.
    2) A stereo amplifier in the bridged mode to drive dual 2-ohm voice coils in series for a net 4-ohm load.
    As long as you arrive at the power you require there is no difference between the perfomance of the two above choices.
    3) You can also go with a strictly regulated monoblock amplifier that delivers the identical power into a wide load impedance range.
    4) Or you can go with a larger monoblock amplifier, that is rated at 1000 watts into a 2-ohm load, that will produce 600 watts into a 4-ohm load.
    It's great to have the type of headroom and reserves that you would get by running an amplifier in a more conservative mode, with scenario 3) or 4).
    The Kicker L7 is a heavy mass speaker and it really likes power. My fear is that within your budget you will find a liberally rated amplifier that is not up to the task. In a brand new amplifier, I feel you will have to invest a little more for the Kicker sub to reach it's max potential.
    Btw, MLA, a Moomba member, has a great deal of experience with Kicker subs so he might have something additional to add.

    I believe I have one of option number 3 above, the strictly regulated monoblock. It's an Alpine and I haven't had any issues with it. It's what I used to drive my sub.

    Would the JL Audio 500/1v2 work? I should be able to find one for between $200-$250.

    That JL 500/1 will deliver 500W rms @ 4, so it will work with your L710 wired in series. So yes, it will work.

    That's a very nice amplifier. Class D. Strictly regulated so that will do it's rated power even with an 11 volt supply. Plus, the power is the same with any load from 1.5 to 4-ohms. Most flexible feature set you will find on an amplifier.
