I currently have a 12" dual 2ohm IDMAX and im just wondering if this JL amp would be adequate enough to power it, keep in mind im using this sub more for its SQ then SPL so I rarely crank the hell out of it. Here is the amp:
JL Audio A Series A1400 Mono subwoofer amplifier 500 watts RMS x 1 at 2 ohms at Crutchfield.com

Adequate....probably.....suitable for your sub.....no....you need that power at either 4 or 1 ohm to work correctly with the sub.....

If you like the JL amps, a used 500/1 would be a better match.......in good shape it will be less money for very solid power......

Hmm ic, why would you need the power at 4ohms though when the sun is rated for 2? Forgive me I still struggle when trying to understand the technical side to things.

its dual 2 ohm subwoofer

it can be wired at either 4 ohms or 1 ohm

and idmax's can handle 1000rms if i remember correctly, so your looking for an amp that'll do roughly 1000rms @ 1 ohm

The sub has 2 2ohm voice coils......wired in series they add up to 4 ohms, in parallel they equal 1ohm mono load, neither one of which is optimal for the A1400.

Section 12 on the right hand side of this page explains how speaker wiring works....

Ok now I got you, so if I was to go with amp from the same series as the first one that I mentioned and run it in a 4ohm load then I would likely need something more along the lines of this then? http://mobile.jlaudio.com/products_amps.php?amp_id=476

Definitely a better choice.........put the IDMax in the right box, hook that amp up and you're good to go....600w should be plenty.....

Hey thanks alot man for the input, after carefully reviewing both amps I think I am going to go with your recommendation on the 500/1. I requires alot less power then the GMAX and its 1.5 ohm stable which is perfect for my needs. Your pretty confident that the 500/1 will have enough juice to run the IDMAX close to or as well as my MTX 225h.o which i currently have powering it?

Thrill_House

I thought I remember hearing that even though the IDMAX could take 1000w rms that it really only required somewhere between 500-600 to play properlly as it is farily efficient. In fact I believe that was one of the selling points on it IIRC, I could be wrong though.

Absolutely.....If nothing else the control over the woofer that the JL will provide running at 4ohm has to be better than the MTX will at 1 ohm.

Since you already have the MTX by all means try it out.....if you're happy with that set-up save your $$$.....personally I think the JL will do a better job, but you know what opinions are worth.....

When you get it done I'd appreciate a listen if we can arrange it.....
