    Re: Beginner System Need Help w/AMP&SUBS

    Well first off, that's definitely not a Sub amp. It's a 4 channel amp, would probably be just fine to power your door speakers Do you have any subwoofers yet? And as for sub amps, you're going to be looking at 2 channel amps you can bridge, or a mono amp. Power relative to that of your subwoofer's rated capabilities.

    Re: Beginner System Need Help w/AMP&SUBS

    No, I do not have the subs yet I was wondering what I should get for my enclosure&budget. I was told JL for the subs don't know about amp.
    Suggest some things that are mid grade maybe? Nothing really expensive.

    Re: Beginner System Need Help w/AMP&SUBS

    @mylows10 less than 3 is not an option I got the box from my dad ($500 box) custom built 3 sub enclosure. Its not really a budget I would just like to know what are some subs and amp combos that would be good for a 3 10" sub amp setup.
    @haze i plan on getting my subs from online. JL or not.

    Re: Beginner System Need Help w/AMP&SUBS

    we cannot recommend subs without knowing the specs of the box. what subs was the box originally built for? you need to coordinate internal volume with the subs you choose. then once you know the subs you're using, decide on an amp to power them at their combined impedance. 3-sub setups were common with JL and their Dual 6 ohm or 3 ohm voice coils.



    have you been helped by me? i'd love to know. shoot me a PM.

    What specs do you need to know? LWH? Or Volume?

    Re: Beginner System Need Help w/AMP&SUBS

    internal volume.

    three subs requires an odd impedance if you want to land on 1 or 2 ohms. three 4 ohm SVC subs can be wired for 1.5 ohms, which a 1 ohm stable amp can do. or you need three 2 ohm DVC subs. all three should be identical both in voice coils and in sub model.

    JL subs are an ideal choice since it is likely the enclosure was made for them. you should try to find out if it was made for W0, W1, W3, or W6. nothing wrong with JL, nothing wrong with buying it from an authorized shop. online you lose any warranty if it's cheaper - just keep that in mind. i believe local shops are more valuable than car forums.

    they are not meant for just low power systems...also depends on what you think is "low power"

    Re: Beginner System Need Help w/AMP&SUBS

    Well I measured the box and the specs are W=3ft D=10in H=13In. With the thickness of the wood being like an inch or so. Doing the math with 1 1/2 inch thickness subtracted it makes my box 3372.375 Cubic Inches. Or 1.95 Cubic Ft
