I should have mentioned that I already have a set of Morel components, my main questions is which way to run either a processor or a line out converter, I dont really want to replace the factory head unit. I can see the processors being better
Nice, Morel makes REALLY nice stuff. JL makes the CleanSweep which is designed for your purpose. The AudioControl LC6i is really popular and seems to do most of what the CleanSweep does for a lot less money.
