: help w/ 99 540i speaker upgrade

07-21-2005, 08:03 PM
hello to all -

i purchased my 99 540i last oct and i am finally fed up w/ the lackluster stock stereo. i would like to upgrade the speakers ( the receiver too but i want to keep the steering wheel controls ).

the only thing on sizes ive been able to find it that it takes 5.25". can that opening accomodate a larger speaker? also, what is the size of the rears? ive searced everywhere and havnt been able to find its size.

i was thinking of focal components for the front and coaxials for the rear. should i even bother w/ the rear door speakers?

any suggestions all round would be greatly appreciated.

many thanks in advance...

Man thats a good question. I have a pair of 6.5's that i took from the rear deck of my old honda accord and would like to know if i could put them in the back of the bimmer without having to cut anything. Those door speakers are so small. I am thinkin of puttin in some Pioneer component speakers in the door and swapping the tweeters out
