My full Stereo upgrade...so far

[Gary H]

The Doors are a little more complicated.
Originally, with the 4 channel Amplifier upgrade, the doors are supposed to contain 5.25" 'sub-woofers' in plastic enclosures:


I managed to get hold of a guy on Renntech who made some custom enclosures from fibreglass and MDF by using an original enclosure as a mould, so I bought a pair and then thoroughly coated them in liquid dynamat and sheet noisekiller.



and then the insides were loosely packed with acoustic wadding -

which males the speaker sound like it's in a slightly bigger box, adding a little 'punch'
As you can see here, one of the advantages of the Infinity Kappa speaker is the tweeter on a pivot and +/- 3dB switch:

and finally fitted back in the door:

With the Sub, I didn't want to compromise leg room, so had to make use of the left hand corner of the passenger footwell. Marking out the area I could lose with masking tape:

and then covering the contours with packing tape...

for the messy, smelly, unpleasant bit: Making the back of the sub box with fibreglass matting, resin and hardener:

Once that had gone off, I used a series of cardboard templates to fabricate the front of the box:

I then attached a 6.5" MDF Spacer where I wanted the sub to be (ensuring there was enough clearance) and then stretched some cloth tightly over it and stapled it behind. Painted it with Fibre glass resin and added a very thin layer of glass matting. This gave me the shape without adding weight -

and then some P38/P40 for rigidity -

Once sanded, trimmed in carpet and a temporary grill fitted.


Sits securely in the corner. Whilst I'm more than happy with the sound, I'm not happy with the way it looks - it's not stealthy enough so will be re-making a box with the sub completely hidden, firing down from under the dash...

So, onto the Power. Really handy having the Battery in the front, it means that power runs are kept to an absolute minimum length. Keeping to the ethos that everything would be hidden - I didn't want to use the standard Amp location and decided a false floor would be the way to go, ensuring that the amps (one 4-channel and one 2-channel) were adequately cooled.)
So the component count is very simple: The two amps, a fused distribution block and a 1/2 Farad Stiffening capacitor. There is also a main fuse attached to the boot wall, approx 6” from the Battery.
The components were laid out on an MDF board cut to shape and then the cable runs decided on:

Then secured to the front boot floor:

I then templated and cut out a ‘floor’ from MDF, incorporating vent holes, a handle (made from Velcro) and a slot fan that shifts a surprising amount of air. This was then trimmed in black carpet -

(Can you see the face?!)
The final touch was to attach a luggage net to it and fit

And by filling in the holes left by the removal of the CD changer and amp, and attaching the warning triangle, I think it looks pretty stock:

Impressive. You've got some good fabrication skillz.

Sensational work! If only you lived in Australia - I would be providing beer and requesting your assistance!!!

WOW!

Now, does it sound like you wanted?

[JettaGLi16v]

Wow, Gary,
that is one of the best installs I have ever seen in a boxster,
and I have seen a few!

I love the slot fan, that is really well done!
Also, no chance of a spare in the factory location in your setup, I assume?

I am settling (for now) with a Clarion CD head unit (w/USB) with 6v pre outs through the factory (upgrade) system, but that is some good inspiration you just offered!

Kudos!
