Hello Brett,

The total upgrade took quite some time. All together I think about 40-50 hours.
The first thing I did, was the upgrade of the speakers. This is something you can easliy do in one day (if you have the right torx screwdrivers of course :-) )
Be sure to use some acryllics sealant to make sure the door woofers are nicely sealed in the plastic 'tubes'.
I would recomment to use the stock speaker wiring.

The most work was to make a nice extension of all the speaker wires to run them to the center of the boot (where the amps are) and to run the power and signal cables orderly.

As the Alto amps do not produce so much heat (because they are class D), I was able to mount them on the cover under the boot-floot. I reinforced the cover by mounting an MDF 10mm panel underneat it, with a small hole on the place where the spare wheel spindle (dont know if that is the correct word )is.
On the spindle I mounted a nut with a large washer/ring, so the whole construction is supported in the center.

I had to cut out a piece of the cover on the left/rear side to be able to mount the alto devices. I filled the hole with glassfibre reinforced epoxy and re-upholstered the cover in grey fabric.

Everything fits perfectly under the boot-floor and have not yet had any temperature problems.

The upgrade is definately worth all the effort. The system really starts to sound like a high end system. I ordered a CREOS FFT spectrum analyser which will hopefully enable me to tweak the system to the fullest.

Keep you updated.

grtz
