What size speakers do you put into a 1992 Honda civic?
Front door 6 1/2 inch and rear deck 6 1/2 inch. You don't need
to cut the wires at all, I just got mine installed in 5 minutes
with the adapter speaker plug, I got them from Amazon for 16 bucks
but you save a lot of time and you don't mess the wire system of
your car with the black tape and stuff.
