woofer impedence Question

so my new amp is 2x280rms @ 2 ohms.. im lookin to get a new setup for my trunk... lookin to ditch my current single ported 10 and get 2 in a ported box.. what im gettin at is, what is the best type of woofer to get so I can run 2 subs off this amp while maintaining a 2 ohm load from it? like a single 4ohm .. dual 2 ohm.. etc..



would this diagram below be my best setup?

280X2....@ 2 ohms, you need two dual 4 ohm subs to show the amp 2 ohms per channel.
if that amp is that power 2 channel @ 2 ohms it should bridge to 560x1 @ 4 ohms, so still two dual 4 ohm subs is what you want..series each sub to 8 ohms,then paralell the two to get 4 ohms to the one channel(that would be the best way.

but in option 2 it shows the amp doing 4 ohm impedence.. is that cause you suggest running it bridged at 4 ohm instead of 2 seperate outputs to each sub doin it 2 0hms?

Ya 4 ohms mono will give you the same power output as 2 ohms stereo, but the mono hookup is the better way to go when running subs .

and if I wanted to go with a single 12 then i'd go with a dual voice coil 4 ohm?

dual 4s= 2 or 8 ohms......
Dual 2s= 1 or 4ohms......
What do you think you should do?
