can someone plz help me... Do anyone know the sizes of the speakers in my bmw. there is maybe 8 or 10 speakers...

I don't know, as I don't have an owner's manual for my 735i, either, but if you go to a shop that sells and installs car stereo equipment, I'm sure they can tell you. You may be able to call the nearest BMW dealership and get someone there to tell you if they are in a good mood that day.

I have a E32 730i (German spec) 1989 model that has six speakers in it. two in the top of the front dash, two kick panels,one at driver and one at passengers feet, they are 5 1/4" and two in the rear deck, with some slight modding, can accomidate 5 1/4" speakers.
