hooking up my subs this way or that way

[skooter]

Hooking up my new Dub200 12" subs. they are dual 4 ohm. hooking up 2 of them to my PPI PCX2200 amp. Should I run them 2 ohm to each channel or hook them both up to a 4 ohm load and run it bridged.

either way is good. but my personal preference is wire each coil in series so that each sub is 8 ohm then wire both subs in parallel to get 4ohms then bridge the amp.

That is the best way. You will also be running higher voltage so it will be easier on the speaker wire.
At work, when running a two channel amp, we always avoid paralleling the coils and running 2 ohms stereo for customers because they could try and change the amp from stereo 2ohm mode and try and run it at mono 1ohm and cause issues. 8ohm at the box terminals means they could never run the amp at too low of an impedance.
