i get asked a lot whether or not we want to work on high end sports cars...and the truth is, for the most part, I'd rather build systems in more pedestrian vehicles. many of the high end and exotic sports cars tend to be less than ideal sonic environments, while requiring a lot of backbreaking labor in tiny cramped interiors. One of the exceptions to that is Porsche, over the past decade or so, i have always enjoyed working on various porsches, i feel that they are pretty well put together, assembled in a logical manner, and can sound quite good with the right build.
So it was pretty cool when a previous customer returned to us to build a system in his 2012 997 S4...a car he had just picked up from a socal dealer. Unlike most other porsche customers of the past, he wanted to focus on sound quality, even if it means loading the car up with a little extra mass...which is fine by my book
so lets get started with the goals:
1. achieve a nice level of sound quality throughout
2. maintain some degree of usability in the front trunk and retain rear seats (he actually folds them down to use as a shelf for a golfbag)
3. design a sub system that can produce a decent amount of output without sacrificing sound quality
so...first up, two shots of the car itself, stock but still very pretty to me:
Joey fabricated a simple metal mounting tab, which bolts to stock locations and houses his stinger fuser holder:
the signal starts with a Pioneer 8000NEX double din headunit, installed via the euro spec connects2 dash kit:
I also added a pioneer ND BC6 backup camera for him, which was loads of fun
moving onto the front trunk. as mentioned, the idea is to still retaining some usable space, so here is the normal view with the top cover in place. he lost about 6 inches or so of total space, but still enough to throw some groceries into it:
lift off that cover and you see a vinyl covered rack with a mesh grille center, showing two mosconi AS 200.4 amplifiers. they power the front stage with 6x200 watts active, and sends close to 1000 watts to the subs. a porsche emblem is in the center of the grille:
lets take a closer look at the construction of the amp rack.
first, all the signal wires were bundled and TESA taped, and routed into the front trunk area via an oem grommet:
then the signal wires went through additional factory grommets into the storage area, while the power cable went down the passenger side:
then, i tapped four holes with 1/4-20 threaded taps into the aluminum crash structure under the floor:
and fabricated a foundation platform with holes drilled to line up with those four threaded holes in the aluminum:
then i wrapped the board in black vinyl, attached spacers, and temporarily installed and wired up the first 200.4 and the mosconi 6to8dsp
i then removed the amp, leaving just the pre-positioned wiring, and bolted this board to the floor using four 1/4-20 bolts into the threaded holes on the aluminum crash structure:
i then reinstalled the amp and wired it up:
then i made the second platform which will house the second AS200.4, and wrapped it in vinyl as well:
then i bolted that board in place and wired up the second as200.4
this is the cosmetic trim/cover panel before and after upholstery and mesh installation:
and pop on the grille, and its done:
and here is the top cover board before and after carpeting:
moving onto the interior. the front stage consists of a set of Morel titanium Elate 6.5" three way set. the midbass as installed in the stock lower door location.
first, the stock speaker was removed and new wires run into the door:
next, the outter door skin was sound proofed with blackhole tiles:
then the stock speaker was separated from its mounting basket, the back of the basket cut out to allow additional clearance, and sound proofed to reduce resonance:
the area round the speaker mounting was then sound proofed, and the stock speaker mounting basket bolted back in place:
then i fabricated two baffles that mimics the shape and thickness of the stock speaker flange, and coated them with several layers of truck bedliner to protect them against the elements:
and then the new morel titanium elate MW6 woofer was ready to be bolted in place:
next, the rest of the door was treated with a general allowance of focal BAM XXXL composite damper:
and then i bolted the speaker adapter plates on using stock mounting points and hadware:
and finally, the elate MW6 was wired up and secured:
the outer door cards on the porsches are pretty solid, but we still put on some STP CLD damper to help with resonance:
