Speaker Question

[bobby866]

Hey I have a 69 GMC project that i am working on and i am just at the point of doing the stereo i have the kick panel speakers and i am contemplating on just installing the speaker on the passenger side because the dimmer switch and the park break are in the way i am also installing a dual voice cone speaker under the dash right about the stereo deck and i am putting the custom auto sound undercover II speakers under the seats just wondering if i am going to notice an uneven sound with only one kick panel speaker. or if you have any suggestions on how to mount the speaker on the drivers side a little more easily without moving all that stuff
