I had an extra mid from a Dynaudio 220mkii component set laying around and thought I could use it as a center channel to give me a bit more midrange up front. I know I can't wire it to my head unit as it's a S4. I'm running my front comps with a PPI PC2400.2 at 4 ohms stereo.
What I thought about doing is taking the negative from the Dyn and hooking it up to the negative midrange output on my left-front comp crossover, then hooking the positive to the positive midrange output on the right-front crossover. I'm on a budget and don't want to spend a bunch of money but want to make sure this will work. If doing this will lower the ohm load I'm not worried as the PC2400.2 can operate at 2 ohms stereo...the only thing I'm worried about is screwing up the imaging on my left and right fronts and/or changing the output of the amp from stereo to mono. In that case my amp couldn't handle 2 ohms.
If need be I'll wait and buy a little amp to run it, but thought I could see if I can get it to work with what's already in the car.
