Default Amp setup questions!!

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!!

Bobby

For the MTX thunderform, you're gonna need 200-250 watts to power it.
I would buy a separate 1-channel amp for it.

100w won't be enough for those woofers.

Is this the power specs for the amp?
25w x 2 @ 4Ohm
50w x 2 @ 2Ohm
100w X 1 @ 4Ohm

The amp will do 100 watts bridged at 4 ohms. IF the amp is 1 Ohm stable (Stereo), rhen is should do 200 watts bridged at 2 Ohms. HOWEVER, do not attempt it if is not. you WILL burn it up. Also, 2 Ohms is half of 4 ohms, and will cause the amp to produce more power, if it is so rated. Use a 2Ohm woofer, or a dual 4ohm voice coil woofer. (connect voice coils in paralell)
