audio question

The problem with running the single 4x10 up front is that you would only be getting the right or left channel depending on which you hook to it. If your radio has a mono feature you could get around that but then you lose the stereo effect. Just do the two 6x9's or make a plate (a member here is selling them pre-made right now in the classifieds!) and mount two 3.5"speakers in the dash. Or, do as BrianT did and rock out! The single 4x10 is only goog for AM radios IMO and not worth messing with!
