So I'm thinking about an affordable head unit:

Crutchfield has this doodad for the Mach 460 system, which is what I have in my '97 Cobra:

Am I going to lose power by purchasing these two items over the OE sound system? Will it not be as loud? :scratch: This head unit is about as much as I ever want to spend on the stereo system; the factory performance is fine for me, but my cd player took a dump years ago & I'd like to add mp3 capability. The only other purchase I might make in the future is an amplified Bazooka.
