I have an 87 volvo 240 wagon, and I'm looking to install some good rear
speakers, but I don't know exactly what I need to do for the wiring.
To start off, the stereo, which is the dealer upgrade digital display
cassette deck, has an integrated fader, which seems to work. (It fades
off the front speakers when you push it so it could fade to back, if
they were there.) From what I could find this means that it already
has the 4 speaker amp installed instead of the 2 speaker amp. Am I
right in assuming this?
Also, is the rear speaker wiring run by default, or is there a way I
can find if it's been installed by the dealer? (This car had only been
dealer serviced when I bought it.)
If the wiring isn't installed, what would be the best (read: fastest
and least destructive) way to install it?
(The speakers are a pair of custom built boxes that should fit into the
back against the wheel wells.)
Thanks in advance,
