thanks very muhc, i hope to have my car within the next 3 or 4 months

Yeah - the two subs under the front seats are 217mm or ~8.5". The mids in the doors and backseat area are 100mm or ~4".

do you by any chance know the sizes of the speakers in the 328xi coupes? with the normal stock system

ohh, wow didnt know that, again thank you very much

The speedometers of BMW's (and almost all other German cars) are purposely offset by ~5%. Seems stupid (and in many ways, it is) but it's due to extremely strict EU regulations regarding how production cars can never, under any circumstances, show an indicated speed slower than what the car is actually traveling.

This regulation is so strict that manufacturers are forced to program an offset into the speedometer. So to answer your question: top speed of the car is an indicated 155MPH, which is more like an actual 147 MPH if measured by radar, GPS, or some other form of speed detection. It's advertised by BMW as 155.

so i was doing some reading up the 328xi and i found that some places said the sport package increases the top speed to 147 and some said it increases it to the limited speed of 155, i was wondering if you knew which one of these is correct?

No problem at all. Feel free to shoot me a PM if you have any other specific questions.

i just wanted to thank you for your opinions/answers to my questions, you were extremely helpful
