Insulated/LEDed, Looking back and forward Options

[mr_dude]

Finished doing an acoustic/thermal insulation job. Pretty much made inserts out of insulation and vinyl to put behind the side and roof interior panels. As a result, road noise is pretty much gone. Can't comment on the better sound since I simultaneously changed from Aiwa-Stock to Alpine-Eclipse, but I'm sure audio quality has increased.
Still getting some noise from the engine. Any audiophilesout there done anything to reduce this?

Stuck some superbright red leds in my dome light. 14 each side. Very nice.
Anyone find clever places to stick LEDs either as a useful light source or to walk the fine line between looking cool and not ricey?
Made some nice, bright tube lights that will illuminate the floor. This will facilitate drunken entry (by my friends, of course) while not giving headaches (as white lights tend to do when you're drunk).

-> easy and fun stuff for anyone with a little money and a little time. Some photos and descriptions up on my site (sig). More to come.
