Installing car speakers in the doors. Part 1
Statement of the problem
The goal was simple - to preserve the design of the doors and the volume of the pockets. Then I saw in the magazine "car Audio" article about the installation of acoustics in the BMW E46, which occupied one of the first places on the competitions. The design I liked and I wanted to depict something similar (Figl us, beautiful women will think "M-Style" with a budget of 10 pieces, we also not bast soup both eating).
I remembered that years 15-18 ago I was model airplanes and decided to go the thorny road construction podiums made of composite material, in other words made of fiberglass. Fiberglass models do generally two ways - by Wycliffe pre-made from the same fiberglass form (that is, first do layout, paste over it with fiberglass, then the layout is removed and the product Vilayat on the inner surface of the form) or just obkleila a kernel. The first method - more correct and only if we are engaged in serial production exactly the same products, the second is much easier. I went through the second (plant podium for Fiat Tipo I will reveal later). And that's how I was:
Long road in the dunes
Now the process in photosHere is materials. Golden is Kevlar, Russian CBM. I in the catwalks not used. Now go to the box for the subwoofer. White the fabric is fiberglass, and the black tape is the same LOOP-0.1. Beautiful, really? Take pocket doors, a model of the dynamics of cardboard, and set ring set dynamics. Apply this to each other to obtain the desired relative position. Cardboard layout use for evidence that the speaker will fit where necessary. I made some cardboard templates to facilitate orientation in space. Use some glue (PVA for example), and screws pieces of foam to secure the structure. Drag in the car, affixed to the door and make sure the pivot angles of the speakers exactly such as we wanted. Proberaum a ruler reference point (subsequently to restore the position of the setting ring about pocket) - we must have a second runway, it is desirable to make it close in form to the first. Cut a hole in the pocket under the speaker and make sure when help cardboard template that everything is in order. This is a picture from the second the podium, so the back of the template is already there, the eye evolved. It's attached to the door trim. Fill the hell with the makrofleks. Makrofleks reluctantly solidifies in large volume, so it is advisable to fill in several techniques, mixing layers by a couple centimeters. Pathetic. Cut with a knife resulting workpiece and work sandpaper. This is the same, but bigger. Please note that the installation the ring dynamics is taken out, I pasted it later, after formed durable composite shell and everything was ready for pasting the vinyl. To make it easier to take out, I put the ring road Polish production of the GDR (was a country, say) - simply put, wax polishes. And then he kicked the knife and neatly extracted. Make sure the "pravilnoy doggay go, tovagischi!" Now cut the fiberglass strips on for about 5 inches wide, dilute with epoxy and forth.The strips before laying need to try on a dry place, to estimate the length and location. Then soak the strips with epoxy (putting on a hard flat surface with effort to smear the epoxy as long as the fiberglass will not transparent), to lubricate the epoxy makrofleks and apply with a small cresting. The first layer should be put rough fiberglass and allow to solidify. After curing, sanding, otherwise all the ridges and nodules will only to intensify. Continue to put the second and third layer of thin fiberglass, alternating a layer of strips from plenty. Placenta should lie along, as if forming a sidewall around the speaker. Layers of fiberglass should be put under angle to each other. A kind of intermediate stage fitting. Black stripe top this placenta. To strengthen her in the first place, those places where all to reach the hind limbs of primates. After obtaining the desired rigidity, hides and shpaklyuem. Jar above is the same Novol. Again hides and again shpaklyuem. And so as long until you get bored or until you reach the desired result. Cut vinyl, cover the underside of the vinyl and the surface podium adhesive spray (grey-red balloon), allow to dry, take Thermopylae and stacked vinyl. Best to first practice on cats, obtenus for example ashtray (cool looks, by the way). If the surface most (I covered the entire pocket), it is better to glue gradually. We need to start with the convex part, not giving the vinyl much to warp. Not overheat vinyl and adhesive, it is better to keep the temperature low and to warm a little longer, otherwise the glue not stick, and vinyl loses its gloss. And here it is, the Golden key. Now all of the same hemorrhoids, for a second time. Podiums two. The second time will be easier.
