Okay...quick question...

Can I drive four of these:

off one of these:

Or will ohm load be too low and burn amp/subs?

Also, can someone post the math behind this, so I can understand it? Thanks,

Oh and how much power will be making it to each sub? Thanks...

That amp puts out the same power at 2 or 4 ohms(1000 watts at 14.4 volts at 1% thd). With 4 4 ohm subs you would want to run a series parallel configuration to end up at 4 ohms. That puts you at 250 watts each.

Disregarding the ohm load labels, is this the proper wiring sequence of which you speak?

Thanks,
