Should i replace the speaker system in my 2005 bmw 325i? Are BMW factory speakers good quality?

I would assume theyre already good quality bc they are speakers that came installed in a BMW, but I do not know anything about speakers or sound quality. Of course i can always get better quality speakers, but would it be worth it if I spent $150-$200 to replace them?|||Actually, all BMW systems are amplified since the late 80's. Most have multi-channel amps built by Philips with electronic crossovers for each speaker. If you have 10 speakers, there is a 10-channel amp.





The speakers are (oddly enough) often made by Nokia or AT%26amp;T.|||If you are planning on keeping your original CD player in there, I would say it is not worth your time or money replacing the speakers. Factory CD players generally don't have enough power to run aftermarket speakers efficently. Couple things I'd reccomend:





1. Add 4 channel amplifier and integrate it to your original system, then replace the speakers.





2. If you are just looking for more volume, consider adding a small single subwoofer in the trunk. Single 10" sub, or a single 12" sub.





3. Consider that if the 325i has a "Harmon Kardon" stereo system, it is amplified and will need to be bypassed if you change your original stereo.
