Hola, senior VR6 dude,
Actually at my old store (we weren't a real high-end store, we mainly sold Pioneer, JVC, Panasonic, Infinity, Memphis), I really liked the Infinity Reference series for the budget minded. They really do a great job and retail for less than 1 C-note per pair. I'm not sure what your budget is but I really havent found anything that was worth having that runs 60-80 per pair. I use the Alpine Type-S speakers at the limo place I work for now. They arent too bad, for the same amount of money, I would still prefer the Infinity's. If you have a Best Buy/Circuit City, swing by and take a listen.
Sound dampening: It depends on if you are wanting to make the car quieter while traveling down the highway, or trying to eliminate rattling panels (i.e. trunk lid, tail lights etc.) Basically all you are doing is adding weight to a panel to lower its resonating frequency. Everything moves when you apply pressure (sound) waves to it. It takes more energy to move a heavier panel, so by adding weight it keeps a panel from rattling. I know most of us are concerned with weight, so lemme let ya in on a little hint if you are trying to get rid of rattles. Only fix what rattles. Get a bass cd that has a lot of test tones, put it on repeat, turn it up, shut all doors (dont lock 'em
) and walk around the out side of the car. Whatever panels are rattling, lay your hand on it to see if it quits. If it does, tear apart that area on the inside, and apply a chunk of dynamat (there are cheaper brands out there and they all do the same function). You dont have to do the whole panel, just add like a 8x8" square and see what happens. You usually dont have to add around the braced areas, they seem to hold their own. You are probably looking for an area that is only one layer of steel (aluminum/plastic/etc) thick.
As far as my new-to-me truck, its kinda funny. I drove it one two weekends ago, after purchasing. It has sat at my work for the last week and half. At 195K miles, the "work truck" interior had to go. Since I work for a limo builder, you can imagine the amount of skilled people we have there. I am getting schooled on sewing. I re-did the headliner and carpet (thats easy we used to do that at the car audio shop), and the guy that sews our seats, took the front vinyl seat and revamped it in some nice cloth. I ripped out the rear seat the other night, and dissassembled it last night and I am going to try my hand at sewing today. We put the front seat back in the other day after finishing the carpet, and it looks like a brand new truck. I will post some pix after I bring it home. Thanks again for the CF.
Ok my fingers hurt, time to go to work, catch ya later.
Hopefully this helps...
