Canadian 320i System Revamp

I have done some lengthy research and have found mixed information.
I am in Canada and have an 03 320i sedan with basic system. It consists of Bus. Class CD, tweeters on each side on the side view mirrors, 6.5"? speakers in front doors, and 6.5" speakers in rear parcel shelf. NO amp in the trunk.

i am currently using a 10" woofer in the trunk via a Line-Out-Converter.
not the cleanest or practical thing.

if i run aftermarket speakers will i HAVE to also run an amp.
what are some good choices for speakers for front and rear.
ideally my budget is around 300-350. i am not an audiophile, but i like good quality sound with a little punch.

any infor or links would be appreciated

No, the head unit has an amp. Replacing just the speakers with better quality speakers shouldn't require a new amp.

after some further research i have decided on the following:
purchase component speakers for the front (tweeters for A pillar, and mid-bass for doors), and 2way for rear shelf.

i am assuming since i have the tweeters at the A-pillar, they have a cross over? or did bmw just add a capacitor to separate the frequencies?

most component sets come with external crossovers. should i be looking for ones that come with in-line xover?

also, should i be looking to match bmw impedance of 2 ohms? or would it be still safe at 4ohms?

I would bet that the crossovers are in the head unit.

Would it be safe to assume I should run my components without xovers?

Check the wiring from a door's speakers. See if the wires go to the head unit. I bet that they do.

Also goto www.realoem.com and enter the last 7 characters of the car's VIN (vehicle identification number; it's on your registration). Scroll down to audio system and see if crossovers are listed.

Will check the wiring.
Realoem isnt quite accurate.
