Editing Subwoofer (section)

===Head Unit connections===

There should be only 3 connections to do. The 2 x phono ones are simple right and left. 
The CDE-9872RM does not have a power control terminal and so I crimped it onto the red power connector from the head unit using a quick splice electrical connector (I had the wiring diagram from the manual to confirm). This senses when the subwoofer should be in the "on" state and makes sure its "off" when the ignition is off.

So now to test. Presuming it's all working you can now work on how to fix it to the wall. There's a nasty big bolt on the Exige just where you don't need it and the wall isn't exactly flat so I used a load of super strong double sided tape. It may not be quite up to track abuse (UPDATE: It WAS up to track abuse) but if I find that's the case in the future I'll investigate some alternatives which may involve a drill as it comes with several brackets and options including one to ensure the cables make a flat exit. Some of the cables are long by design (to allow for other installations) so you'll have a lot of cable ties to do to tidy up the excess.

| In situe, time to tweak the settings and tidy the cables. You can see the remote at the back of the shelf (will glow blue when power is on)

The two loose cables you see in the last image are a USB power supply (run on a 3M USB cable from the 12v socket on the back wall between the seats) and the iPod cable (from the Head Unit) installed at the factory.
