Hi, first, i don?t speak english very well so perhaps you won?t understand me J I have a pair of 6x9?s in the the rear shelf, a pair of 6? ?s in the front doors and a pair of tweeters on the front dash and it sounds good but there?s one thing I don?t understand, I know bass is not directional, so you can put a bass speaker (a sub or a woofer) wherever you want (into the car, obviously), and the mid and high frequencies are directional so you will listen to this frequencies from the place where the speakers are, well, when I (how can I say this? Lol) put my head near the steering wheel the bass sounds better, the 6? ?s are fitted where everybody fits them, low and near the dash (I don?t know the exact words, sorry). That?s the thing I don?t understand, why sounds better when I put my head near the steering wheel if the bass isn?t directional? Because mid and high frequencies sound =. Thanks
