i'd even go as far as recommending you mount the speakers in a manor that reduced vibration (using rubber washers and isolators). the trick is to reduce the excess car vibration.
sound in a car should be clear, high volumes are easy to reach in such a small space. even the slightest unwanted vibration can spoil the whole sound.
so there's a possibility of there being some gain in a tuned cab rather than a speaker box (if you get me). look into it bud. it could be cheap to do and could make your sound system sound like something 5x the price.
for me, it's not about having the badest ass speakers and the biggest amp. bass tuned correctly should be subtle and tops should be crisp. but if you're going to then play mp3's @ 128k bitrate then it's not as important.
i thought the little would have been enough to show i was joking. i guess not.
i agree with Kev, although it might just look like the speaker is put into a wooden box and then covered with carpet. if you're making your own cab, you need to think about the direction of the speaker (facing into or out of the cab). also, where to position the air inlets. some bassbins have sponge in them to help keep the sound clear and the (excess) vibration low.
because your car is essentially a cab, keep the bass speakers as low to the floor as you can. tweeters go high )not too much higher that head height)
no you won't. remember i said with good cooling? that usually means that your case has well, erm, good cooling. it doesn't mean that your pc melts down once you add even 1Hz extra to the GPU. and are people still that anal about the sound of one fan being louder than the old one? i don't notice the one on the GTX470. i know it's spinning but it's no louder than the fans on my chassis. At least with a loud fan, you know the unit is working. also his location meant the price difference between the card he bought and the card you wanted him to buy was too great for such a small gain. so, although it might have been feasible for you to buy the "better" card. for PLAYAPIMP, the benefits were just not as big(card is more expensive).
although you're not wobbly fruit flavoured water, could you name a British car or an american car you'd be excited (for want of a better word) to see? the Nissan is going to be a popular car in a region that isn't far from where it's made.
To put it into perspective, I don't see why people get excited over coming to Ireland and drinking a Guinness, but they do. Americans don't really care for climbing up to the top of a tall building in one of their cities, just to look at the rest of the city. But how many tourists visit the top of the Empire States Building?
People get excited about driving the autobahn. To Germans, it's just a motorway.
I hope this helps you understand better.
