So please don't hate me for the awesome hardware in there, I just count myself lucky enough to even own it!
Alrighty then, kicking off with the car itself first.
It's a 1996 Peugeot 106 with a whopping 1.1L (or 67Ci) powerhouse in it, some serious high performance for sure!
Okay, it's kinda small, and yes it's French.
Before the *boo!*hiss!* remarks start flowing this way, it was cheap, it drives cheap and gets me anywhere I want to go, so there.

Normaly I would have shown the stuff under the bonnet next, but I couldn't be bothered popping it open.
Sooo, moving along to the rear!
How's that for a stealth build then eh?
Actually there's nothing in there, the stuff in the front is so incredibly good, I don't even need no stinking subs in there!

With that said, let's hop inside...
Head Unit first I guess. This badboy packs quite the punch let me tell ya.
It blasts no less then 45Watts RMS through that high-end speaker wire.
That's right, 45Watt RMS!!!
It says so right there on the front of the unit, and as we all know manufacturers never lie, right?

Moving along to the cherry of all this High-end goodness, the speakers...
As you can tell right away, no expenses where spared in the front here, that is some serious high quality speakers right there people!
The tweeter is a Visaton connected with some very high-end speakerwire I found in the trash someday.
Can you believe some idiot threw this away??? Me either, so I took it home with me.
The right tweeter doesn´t seem to be working anymore for some reason, I left it in there though, for cosmetic reasons.
In the doors there's a pair of 10cm (3.9inch) Visatons I had laying around.
Interestingly, the righthand speaker stopped working some time ago aswell.
When inspecting it, I noticed it changed color from deep black to a kind of brownish (looked a lot like rust actually)
So obviously that explains the high price of them, they can change color!

Lazy git that I am, I could not be bothered to try and find out why the righthand unit had stopped playing.
So decided to add a sub on the right channel instead, for even more bass!
Who needs stereo anyway, highly overrated if you'd ask me.
Since only pansies go with sealed enclosures, and it takes a complete nitwit to even consider a ported one, I went the best way known to man... Bandpass baby!
Well, in all honesty I just happen to have it laying around, and it being of such awesome quality again, I kinda stuck with it to save time.
Here's that ground pounding badboy up close...
Left:

And right:

Here's a closer look on some high-end filtering, let me tell ya, this took me some serious calculating right there.
Not sure on the port tuning though, but I have no doubt this monster will have any trouble whatsoever reproducing 10Hz frequencies!
What with that Visaton 17cm (6.7 inch) in there and all, hell yeah, easy!

So just how good does all this awesome hardware perform?
Well let me tell you that whenever I crank this insane build up to the max with the windows rolled down, absolutely everybody looks at me in awe.
This level of pure sound-quality is so high even, that it makes most people shake their head in disbelieve.
It really is that good.
