Installation Instructions
Introduction:
The procedures outlined in this document are intended as a guide to assist in the installation and
modification to allow buffered line level outputs and/or Auxiliary Input. There are people of many different
skill levels out there, and the instructions have been formulated to cater to many different levels. Whilst
something may seem mundane and obvious to you, it may not be to everyone. I do encourage reading
through the procedure entirely and to clear up any points of uncertainty before commencing.
The job entails the mounting of one or two small PCBs (Printed Circuit Board) and attachment of an
additional socket inside the head unit, and the cutting of a small slot into the cradle metalwork to facilitate
mounting of the pins which mate with the socket. The kit consists of a small PCB containing the buffer
components, the additional socket, a lead-out cable assembly terminated with gold RCA sockets and a
bullet connector, a guide template to assist with the positioning of the slot which is to be cut into the cradle
metalwork, some various internal hook-up wires, nylon standoffs to support the board(s) once installed, and
a length of 0.5mm solder. On completion of the modification and re-fitting the unit to the vehicle, there is
absolutely no visible evidence of any departure from factory stock – nobody will know until you turn up the
volume control.
The operation of the internal amplifiers remains unaffected, so if the time comes to move the car onward but
you’d rather hold on to the “external” components of your system, the standard connections can be restored
to the door speakers, and the unit will continue to function as it always had.
The work involved does require some moderate soldering skills, and a generally handy nature with hand
tools. Do not underestimate the potential for damage to occur – there are several connections that need to
be soldered to the base unit PCB, which is heavily populated with “Surface Mount” components. As a
general guide, if you’ve ever fitted a “mod chip” to a Playstation (or especially a PS2!) you will have little or
no trouble with this aspect.
