I would to start by recommending the PCH8 to anyone that's wants to keep their stock radio and add an aftermarket stereo with processing. I had been originally looking at a lot devices and they had one big negative which was they all had eq's built in. I first looked at the JL cleansweep, but that was off the list because you have to use their supplied volume controller and cannot use you factory volume controls. Then I was in my local shop and they had recommended the PCH8. What sold me on this was that it allowed me to add an aftermarket stereo use the factory volume control and it does this with out any eq's so that I can use my own processing.
