The Honda CD Changer is an Alpine OEM
and works with the standard Honda head unit in just about
all Honda's (including my girl friends 91 Civic). It connect
via Alpine's M-bus connection, which requires just one cable
for control and audio (I can hear the purists
shreik). The changer is mounted in a bracket on
the left side of the boot. As a result, it takes up much of
the S2000's very limited boot space. An alternative location for
aftermarket installs is in the well in the botton of the
trunk. I am replacing the standard audio
system with a Sony CDXM750
head unit and compatible changer. I chose the Sony Xplod
CDX737. This unit is a 10 disc stacker and is
considerably larger than the Honda unit. However it is only
5mm wider than the Honda unit but this still necessitates
modifying the bracket. I used an angle grinder to grind the
seam welds on the forward side. I then welded it back into
place 5mm wider. I then had to redrill the mounting holes. I
used the supplied plastic mounts as templates. In this shot you can see I have
removed the head unit and the inside left kick-panel. The CD
Changer cable runs to the left and along the transmission
tunnel under the carpet. You only have to pull out the
plastic plugs which hold the carpet in place and pull the
cable out. You can see the cable lying along the
seat. The cable runs behind the left seat
under the carpet, and then up behind the plastic panel that
the optional luggage nets attach to. The bottom half of the
hooks unclips to reveal screw/bolts. Use a phillips
screwdriver or small socke to remove the screws then pop the
panel straight out. This shot is looking down behind the
passenger seat with the panel removed. The cable is longer
than necessary so it is bundled up behind the panel.
After you remove the spare wheel and
some of the plugs holding the left panel in place you can
fold it back and get access to the cavity behind the left
seat. Notice the string to the left which goes under the
petrol filler pipe. This is the string I attahced to the
cable before pulling it through. You can see where the original CD
Changer was located and the ball of string I am using to
chase the cable as I pull it out. After reassembling all the boot panels
I mounted the new changer in the modified bracket in the
original position. The cover still fits the new changer
and finishes it off nicely.
