A few guidelines I like to follow:
- you're in a small reflective environment. plan accordingly. watch out for wide dispersion if you can. there are only so many "sweet spots" required in a car. dont waste power response.
- the further the drivers from your ears, the less the time delay will bug you and mess with your imaging. you can do this physically (kick panel tweeters/mids) or electronically (digital time alignment).
- corrollary to the previous note, watch out for time misalignments at crossover points. if your tweeters are far from your mids and not at the same distance from your ears, you will have time / phase issues.
- know your car's transfer function! you'd be surprised how much "free bass" you get in a small enclosure like a car. some cars require high pass filters on subs well into the 50 or 60 Hz range. HIGH pass.
- plan for a little bit more bass than you would in a quiet environment. cars generate a lot of noise and you're going to need to equalize to compensate. be prepared to need somewhere around 1 db per octave as you go down in frequency from around 500 hz. that'll raise your low end 4-5 db.
