dual 2 ohm or dual 4 ohm?

[yotamutt 10+ year member]

I'm considering a sub driver that is available in D2 or D4. The class d amp I'll be using will drive the same wattage into both. Would either be better than the other?

Thanks for help.

Technically wiring higher is supposed to yield lower distortion. Won't be audible unless you have exceptionally trained ear, and possibly not even then.

So what is the reason they are availabe in 2 and 4 ohm? Is it so they are campatible with the most common amps?

They offer both so you can wire them at different ohm loads... a dual 4 can be wired at 2ohms and 8ohms... while a dual 2 can be wired to 1ohm or 4 ohms...

id get the D4. that way if you want to get another one in the future and a more powerful amp you can wire them down to 1 ohm. ***most*** mono blocks put out the most power at 1 ohm. this is just thinking ahead. right now, it doesnt matter which one you get.

a helpful piece of info would be be to know what amp you have, what sub your looking at, and what the rms is on said sub

I suppose so haha. I just assumed he was running a JL Slash or one of those PG amps that put out the same power at 1-4ohm. I guess it's better not to assume though.

So, with d4 wired in series you get 8 ohms, and in parallel 2 ohms? Do I have that completely backward?

That's correct

There ya go ^^^^ When you start adding more subs it starts changing thou

This is a good site to help you figure this stuff out. Once you understand the basics of what happens when you wire series vs. parallel, you're golden, but it never hurts to double check using this or the various others that can be found online until you're your completely solid with it.

I have a pdx5 that I plan to hand down to wife's car. I'm considering the Elemental Designs e3.8 in a small enclosure made by self, for a clean stealth install with decent SQ. website says 200-400 rms.

that amp dosent run at 1 ohm its a 5 channel get the dual 2 and run it in parrallell

D2 in parallel is 1 ohm... He should either run a D2 in series or D4 in parallel. I think D4 is wisest do being able to wire to 1 ohm in the future if the addition that a second sub is added.
