I just picked up the carbon fiber (CF) model of the z5000 series cadence monoblock amps.

It produces 750RMS@2ohm, but only 25@4ohm, Why is this?

This really limits my choices in dual sub setups, unless someone can tell me a method of making say, two dual voice coil 4ohm subs into 2ohm.

Etc...

Anyone know much about this amp? Is it good? I've only let it push a p3d412, it rocked it - but I'm looking for a dual 12 setup, or some other setup that produces more SPL. (In the market for buying right now if anyone has anything).

Yeah,I know - but every source I see says this amp only puts out 25-75RMS @ 4 ohm, and is only effective in 2ohm mode, at which it puts out 750 ( I can confirm the 750 rms@2ohm, as it beat the living hell out of my p3d412.

That is correct...... most cadence amps are that way, they only produce any meaningful amount of power at their lowest ohm load.

So, you need 2 DVC 2 ohm subs, or 2 SVC 4 ohm subs to use with that amp.

Okay =) That's fine, was just curious. It's a really nice amp from what I can tell (For my budget anyway, I know you guys have a lot more spare money and can build more impressive systems, but for me, this is nice - and I'm happy with it)

I'll find some speaker configuration that works out well for me =) I was told in the subwoofer forum that for this amp, the highest SPL budget sub I'm going to find is an L7, so perhaps I'll go with that!

Don't get an L7 if you plan on using this as a daily system at all. Their SQ is crap.
