Hi here is my parts list

Fosgate 200a4 - 50 x 4
PPI 225 - 25 x2

Focal 6.5 coax for the rears
MBQuartz 6.5 components for doors

Alpine head unit cda-7892

MTX stealthbox 10 the THuderform or whatever.

Here is my question I bought the PPI to run the sub at 100 watts rms bridged is that going to be enough? If not could I get an 8ohm sub and run it at 200 whats bridged? The documentation says that if you half the ohm load it will double the power??

If not and I should use the rear channels Of the FS for the sub could I use the PPI for the 6.5 focals (they are the cheaper 229 not the bad boys)

Love PPI amps and got this one for 75 shipped so I figured I could use it somewhere? Any suggestions? Thanks!!
