I have 4 Pioneer Marine Speakers installed about 4 years ago. They don't make these speakers anymore. The speakers are ok for my application, but I was told these speakers did not have the right measurements for aftermarket bling. Does anyone know if that is true?

What size? 6.5" etc.?

My Pioneers' are 6 1/2. Although the place I bought them says they are larger than normal. Does this mean that I can't use the aftermarket covers?

6 1/2s are a very popular size. There are some 6 3/4s out there too but I THINK a 6 1/2 cover will fit.
