I recently invested in a new sound system for my W124. I choose to go with an all out Blaupunkt Overdrive system. They just came in today, I just realized the set of 1" component tweeters I ordered wouldn't do much good considering how I am using a coaxile setup instead of a component one. Could anyone explain what effect these tweeters would do to my system if any? Thanks...deciding wether or not to exchange them.

Blaupunkt Malibu C50
5 disc in dash changer
4" Overdrive Speakers
5.25" Overdrive Speakers
1" Overdrive Tweeters
50x2 Amp with Crossover
2 8" Subwoofers

If you own coaxials you don't want to use separate tweeters. The coaxial speaker contains a tweeter, woofer and a crossover. Another tweeter would just duplicate the signal produced by the one in the coaxial. Component speakers almost always perform better than coaxials, but since they usually involve more difficult installation, and possibly having to cut up your door panels, many people go with coaxials. If you do decide to go with components, do yourself a favor and buy a power amp. The dinky amplifier in your head unit will not do them justice...

adding a set of tweeters could add a lot to your sound - components consist of a tweeter, a woofer (midbass), and a crossover, which usually sets the tweeter to 35000hz+, and the woofer to like 500 and under or something like that. As long as you have the passive crossover for the tweeter, and sufficient power for it, put the tweets in the dash. That way you have strong highs up front, coming from the tweeters and the ones on the coaxials. If the seperate tweeters sound a lot better than the coaxial ones, or the highs are too much, set the coaxials for midbass, using either the low pass on your amp, or by attaching them to the woofer part of the tweeter's crossover.
