Default Second that (e)motion

For a car, overdamped sealed boxes seems to work the best for me. I ended up with a reasonable 120dB flat with two 10" drivers and 200 watts x2. The hardest part was finding a parameteric eq and an adjustable crossover. Between the two, I have enough "twiddle room" to make it sound decent.

Priority number one is damping all of the car somehow. I guess I probably ended up adding 100lbs of dynamat and the like by the time I ended up chasing down all the buzzes. Major time eater, running a freq. generator into the car and hunting down the part deep in the dash that is making all that noise. (OK, I might have gone a little overboard with fiberglass in the doors). But if you are not willing to spend the time to do the basics, you might as well go buy some generic boxes from BestBuy.

Thanks, I have noticed how bass acts in small rooms and decided it wasn't worth while to try and get deep bass in a car. I hear guys driving by and it all sounds one note to me. I also have wondered if there is a health problem from being concussed for long periods of time. I was always carefull about my hearing and used earplugs at rock concerts when I was a kid. They were so loud and a lot of the venues had such lousy acoustics you could actually hear the music better with your ears plugged so you couldn't hear the standing waves. I will admit that using some of the insulation in the cab of my truck would be helpful even if I don't go for more bass. The road noise level is pretty high on the freeway and I have to crank the player up enough that it often clips.
