How is a "JL Audio 10" 10W3v2-D4" a "dual 2 ohm subwoofer?"

That is what I got off the website...

[hehe]

An amp that runs at 1000 watts at 1 ohm, ran at 4 ohms.

This way, when you upgrade, you don't have to buy a new amp.

There's a Memphis MCD1000 on here for like $200

That's what you need

I am quite familiar with that particular subwoofer (hint check my signature). They came in Dual 2, 4, and 6 ohm versions. A 10W3v2-D4 DOES NOT have dual 2 ohm coils!

I don't know jack about it which is why I went to the website and looked it up.

So based on what you know, what do you think about the right amp to power that?

Well, if you have a dual 4 ohm sub, you need to find something that delivers 300 watts RMS @ 2 or 8 ohms. If you have a dual 2 ohms sub, you need to find something that delivers 300 watts RMS @ 1 or 4 ohms.

**THIS** amp will give you 350 clean RMS watts @ 2 ohms. Ignore the 750 because that is peak output and a big fat lie with regards to RMS!

**This** amp will give you 300 watts RMS @ 4 ohms

It really all boils down to how much you want to spend and what your goals are.

Great explanation, thanks for breaking it down for me and thanks for the rec's on the amps!

I am not familiar with the Crunch name, but have def heard of RF. Since they are both the same price, which one is best to get? I noticed the RF is an AB class amp whereas the Crunch is class D, so would I be better off with the Crunch for the sub?

I don't know of it matters, but it will be mounted in a Jeep in a smallish location, so cooling and 'weatherproofness' is a concern.

Thanks again for the help; I really appreciate it!

I have a brand new in box old school Soundstream Rubicon 302 if you are interested. Puts out 300 watts @ 1,2,4 ohms bridged.
