Subwoofer Information
From comparing the guts of the sub amp to other ford stuff it looks exactly like the mach 1000 bass amps, which would mean it is 85 watts continuous, according to their specs. Of course, we don't get the word MACH slapped on it.

Speaker Information
The speakers are marked as 4 ohm, 25 watt. Like all cars, they have paper cones which are crap.
I'm not sure what the subwoofer is as there is a pad stuck on the bottom but I'm guessing 4 ohms as well.

So finally, the system is 22x4+85=173 watts. Does anyone remember what they advertised it at?
