Couldn't tell from your boneriffic posts

Hey! Starting a little build log for my tiny little car, a VW Lupo: Modified with coilover suspension and some old OEM Porsche 928 wheels. Pretty much stock outside other than that System overview: Pioneer DEX-P99RS head unit with 4-way XO, 31band eq, time alignment and more Tang Band W3-1878 3" fullrange drivers on dash playing 200hz and up Digital Designs DDW6.5 midbass drivers in doors, playing 60-200hz FI BTL N218 (fully loaded) D1 subwoofer Phoenix Gold Outlaw 1845 amp for front stage speakers SPL Dynamics ICE-3500D for N2 sub Kimber Kable 4PR speaker wires for front stage 4x Supra Dual interconnects 1/0 gauge power wires 120A stock alternator XS Power D1200 battery up front Second Skin Damplifier mats, 2x in roof, 3x in doors and quarter panels, 1x under carpet and in boot. 1/2 inch closed cell foam on top of damplifier Some pics, starting with wiring: Amp/subwoofer rack/mounting frame: (only tackwelded in these pics, will be fully TIG-welded when finalized with all braces) More to come!

Keep in mind that article only deals with the "impulse" side of the transient response but not the "decay" side of the response, which is dictated primarily by system Q. And yes, you can have too much motor force.

They do not have a copper option either, there is only 1 coil with the Q either D1 or D2. You can only do a partial BP cooling system on a older Q that does not have it..and it does not work as well as the full out BP.

The 3k at 2 ohms.

Its past midnight, and bedtime here in Norway, so just throwing out a pic of a part of the subwoofer box before I head off to bed

Just throwing in some random pictures of the rest of the car and what has been done. When I got it, it was completely stock: First mod to the car was coilover suspension, helped a lot Maybe a little too low for crappy roads like on the island I live: Porsche wheels on, with pretty agressive camber Wrapped the roof in carbonfiber vinyl: Also did the hood; but did not think it looked quite right, too much black on the front of the car, it kinda took away from the black roof Took it off, and got blacked out headlights instead, with tinted indicators and carbonwrapped grill Wanted something different after a while, so the vinyl on the grill came off and the indicators were tinted yellow instead:

I actually started building a box for the Utopias, and had it about 80% complete when I decided to use something else, haha.. I'm terribly indecisive Can show you some build pics of that box anyhow, its junked now And some amps I have (well I sold the Tru Tech Copper tube amps for $3000 a few weeks ago)

Made some spacers for the door speakers, was at first going to put Focal Utopia midbasses in there. Two 19mm MDF-rings glued together Mixed up some polyester resin and hardener, alot ot hardener in fact, it is NOT supposed to turn dark purple after 2 minutes Coated the mdf with resin, as mdf is not waterproof and swell up when wet. Now they can live in a door in rainy norway. Finished them with some filler and paint, they wont be seen when the new door panels are back on, but they do look a lot better like this Found the Jasper Jig to be very accurate, I got the mdf rings so precise that the speaker actually pressfits to the rings Tested with the Utopias: Sadly, even though I was sure I had made these waterresistant with the polyester coating and gloss paint, they drew in water and swelled up so much that I just had to remove them and throw them away... Started out with some new ones that needed to be deeper anyway, because of the mounting depth on the DD W6,5 drivers: Speaker adapters/spacers V2.0: Triple layers of 19mm mdf, bonded together and sealed with three thick layers of VPA, this time they shall not swell up like the first ones that were sealed with a layer of polyester. They are bonded to the doors with Sicaflex for a perfect seal. And seeing how much work it was getting the old ones off, I think they will hold up just fine being bonded only to the door metal.

Sneak peek @ the subwoofer box

And some pics of the finished pods: Only blue because that was the only colour gloss spraypaint I had around, needed to spot them for defects in the finish. But looked good, so they were wrapped in carbonfiber vinyl to match the rest of the dash inserts: and the passenger side looks like this finished:

Making pods for fullrange speakers: I wanted fullrange speakers on the dash, but there is just some small tweeters there originally, so I had to modify the dash a bit Since I wanted these neodymium long-throw wideband drivers I had to come up with something: I want the 3" fullrange drivers close to where the stock tweeters are/were located in the dash, close to the corners. So I found my Bosch "dashboard muncher" and got to work: does this; They fit pretty well: considering their mounting depth/magnet assembly: Other side: Routered some speaker rings Took a few pics while making the base for the speaker mounts: Step one; ducttaping where the base is going to sit Step two: masking everywhere you are going to make a mess and spill resin: (done this before ) Cut some fiberglass fabric to form the base: Coating it with polyester resin and waiting for it to harden: This morning it was ready to be cut approx to size: Superglue and pieces of cardboard are key components for angling speakers Filled out with fiberglass putty for strength: Some more fiberglass outty: Testfitting of fullrange speaker: Angling pretty much straight up at windshield. After a good few rounds with body filler and sanding, trying out some high rise spray filler here. Starting to take shape:

I wonder how much, if any besides the body, of the original car is left...

superglue the fuck out of it front and back and see how long it holds up? if you decide not to recone at least put it up in the f/s section, im sure someone will pick it up.
