used these to replace the rear speakers in my 525i. These speakers have a nice crisp sound and it carries itself to the front well, especially those crisp hi-hat patterns in southern rap music. I like them alot, although its ability to achieve nice deep bass is limited by its size and enclosure from the stock speakers. Very good speakers if you want the crisp highs from a set of 2 way speakers and overall really nice quality in sound.

Customer Testimonial

All I can say is wow!!! It's unbelievable the service, I ordered a car alarm on June 8th and it was delivered on June 9th. I didn't pay for overnight shipping but I'll be back for more ordering. Getting the right merchandise with fast delivery, you got my business way to go! Great customer service!
