well, start by returning the dual 4 ohm and get a second dual 2 ohm and then youll be in good shape....your looking at either 1 or 4 ohms from the dual 2 ohm and either 2 or 8 ohms on the dual 4 ohm sub....

Also remember that the power won't be divided equally.

if you are wanting to run these off a single amp channel the best you will do is 2.66 ohms by series wiring the voice coils of each sub together and then parallel wiring each sub back to the amp......

You cant...

To do Ohms like that THEY HAVE TO BE THE SAME EXACT SUBS.

So no you cant combine these like you think you can. Yes it will work, no your power output wont figure out to what you thinbk it will.

the dual 2ohm is an alpine type S and the dual 4ohm is an alpine type R

the dual 2 ohm one just run a jumper from one vc + to the other vc - and use the remaining + and - back to the amp the dual 4 ohm one if you do that will give you 8 ohms, but if you connect all + together and all - together and back to the amp will give you 2 ohms. there is no way to get 4 ohms with that one.
