I Just purchased a pair of Focal 690 CA1 6x9's for up front, they are almost 2cm shorter than the bostons. This easter weekend Im gonna give it a crack and try and install the speakers, If I cant fit them I'll just get a refund. The reason I dont want to put splits up front is because I'll most likely want a sub. I have MB quart Q series 6.5 inch splits in my supra, and without the subs on, they dont provide any bass. I listened to many 6x9's, Mb quart, boston, rockford fosgate, jbl and many more . The MB quart dont sound the same as they once did, They were bought out by rockford fosgate a few years ago, and now by maxxsonics. Yesterday I listened to the $199 pair of Focal 6x9's and man was I blown away by the quality for such a low price. Highly Recommended to anyone looking for 6x9's. I just hope they fit. Bought the bostons for $137 cost price because my cousin works at lifestyle store, unfortunately lifestyle store dont sell focal. thanks for your advice and information. I'll let you know how I go.
