I bought these for my 1972 F250, the problem I had was that the speaker fit fine under the drivers side of the seat, but I ran into a problem with the wire that goes from the drivers side seat adjuster lever to the passenger side. The wire hit the speaker on the passenger side. My bench seat would not move forward without catching on the speaker. I ended up putting the speaker on the top of the transmission cover hump, as my truck has an automatic transmission.
