I just had a new head unit, amp, and front kick panel speakers installed in my '96 328i. Also, the stock door tweeters were cracked, so I purchased a new pair (pricey) from BMW, mainly for the appearance. The rear panel speakers are still the stock ones. The kick panel spakers are Polk components, (recommended by an advisor at Crutchfield) but the Polk tweeters aren't being used, since the new BMW (HK) tweeters in the doors are hooked up. The door midranges are now disconnected, because both were blown.
The new system sounds good, but I feel something's missing, possibly because of the disconnected midrange speakers in the doors. The music seems to reflect this, bass and highs seem quite strong, but the midranges seem a bit subdued (which is also apparent with vocals, at times). Also, when I put the fader to only the rear panel stock speakers, it becomes noticeable how superior sounding the new front (Polk) speakers sound, compared to the rear old ones.
I'm now wondering if I should also replace the rear panel
speakers, and the midranges in the doors. Can anyone tell me what speaker options I have? I understand the rear speakers consist of two per each enclosure, but I have no idea what the sizes are. I also don't know the size of the midranges in the doors. My car has a tan interior so I had wanted to keep the speaker grill color on the doors, but I suppose black wouldn't be too bad, if I changed these out. I just don't know what sizes & speakers would work. Of course I could also order new midranges from BMW.. again, not exactly cheap, and I'm not even sure they'd be the best choice for sound/performance.
Any insights would be appreciated.. email@example.com
