I am sticking with Image Dynamic for IB subwoofer, ID10. I am not sure which one to get, the 2 ohms or 4 ohms? Will the 2 ohms get me more punch out of my sub since my amp will push 600 watts at 2 ohms and 400 watts at 4 ohms?

I am powering the sub with an Alpine MRP-M650.

You'll want the D4 (dual 4ohm). Wire the coils in parallel to achieve 2ohm.

how will i do that?

Wire all the (+) together and do the same with the (-).

thanks for the help

It doesn't matter. 400w or 600w - 400w will push either driver to their mechanical limits easily. You better set your SSF in the 30hz region.

Both ID subs have a Qts around .3 and a low Vas. Both T/S values are much lower than your standard IB sub.

I personally would not run that sub at 2 ohms. The driver is rated for 250w RMS. In an Infinite baffle setup it is quite easy to reach the excursion limits of the sub. Overpowering can very easily drive the sub past its limits and then you will be back to square one......only with a few less dollars in your pocket.

Turn down the gain to compensate for the 2 ohm load. Worse comes worse, you can wire the coils in series for an 8 ohm load. The amp will output approximately 200w RMS which is enough.

Or just buy the dual 2 ohm, run them in series @ 4, get 400 watts, which is 200 per coil, and call it a day. Amp runs cool, sub isn't getting hammered, you're bumping along and enjoying. Sounds like a winner!

^ interesting point. that does sound like the winner and both sub are the same price.

but how will i get that wired correctly? hahaha
