So i have hi fi system in my 09 335i, can i just replace front and rear tweeters to logivc7 tweeters, would it improve sound, would they work as plug and play?

The weakest part of the Hi Fi system is the Amp.
That is the place to start for the biggest improvement.
After that the front speakers need to go both doors
and under seats.

Thanks for links but im happy with hi fi, my question was that would these tweeters work with my current sound system? And would these tweeters make sound a bit clear? Im getting front and rear logic 7 tweeters for$50, im on budget and want to make little improvement.


Thanks

Hello,

Tweeters will work, but the ones from the HiFi system sound OK if you give them a better filter + add a LP filter to the HiFi midrange drivers. These drivers are voiced together and the match is better for hifi/hifi (or logic/logic)than between Hifi/Logic drivers.

Benefit from implementing better filters are that you will help the drivers to play in a better defined area where they perform better.
Especially by adding a x-over coil to the midrange (0,22mH) you get a good improvement. For the Tweeter I would add either 5.6uF as a replacement to the current electrolyte or a 12 db/oct filter w both a capacitor & a coil.

Hope this help / clarify.
