Query: buyer beware !

Of the many purchases I have made on Amazon.com over the years, this is the first one I have been dissatisfied with. The mat fits the dash correctly, but covers ( no cut-outs) the stereo speakers. The installation instructions say that this will not affect the sound of the stereo, but clearly does. My dash was thoroughly cleaned with alcohol before attaching adhesive strips but after a couple of days they quit sticking and mat refuses to lay flat to the contours of the dash. I am currently looking for another adhesive alternative at the current time.
