Yeah,my old Harman Kardon in my ex E46 sounded better. You know that the radio loudiness is capped Try raising the volume to all its got, it gets a bit loud but if you have the windows open and driving you can hardly hear the radio

To some that ask about the speaker locations; there are :
2 tweeters
4 Front door midrange (Actually there are 2 in 1 )
2 under the front seat for bass (they SUCK)
2 on the rear

So far reception has been OK. No problems witht he radio stations I use but again there is nothing in FLAT Florida to block the signals
