i can get a clarion DXZ835MP for $200. is that a good hu and is it a good deal. i will either put it in a 97 ford F150 extended cab or a 97 ford expedition.
2 volt is "average" and 4 volt is what you really want if ya have a choice. the pre-out voltage is the signal voltage sent from the radio to teh amplifiers across the RCA cables interconnecting the two devices. The higher the signal voltage is, the cleaner and higher the resolution, so the better the end result will sound. that's all it means.
