Just replaced the stereo in my car (Subaru Liberty GX 1994) with a pioneer DEH-P4650MP (mp3/wma/cd/tuner) whilst everything works fine. I find that the AM radio is very crackly and noisy when the engine is turned on. If the ignition is in the Accessories position AM radio is fine.
I've also replaced the car areal with an oem replacement.
What I need to know is how to eliminate the crackling and noise from the AM radio that appears as soon as the engine is turned on.?
p.s. never had this problem with the old deck which was an OEM clarion AM/FM/Casette unit.
