CD Changer or Stacker

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.
