Im looking for the instructions for the psb alphas. there is a place that tells you how to seal them off for better sound and sand the port, little things like that. thanks in advance.....

I have a pair of PSB Alphas, and I don't know why you'd want to modify them. They sound fantastic as they are.

there was this site that shows how to seal them off a little more, they can handle a little more power then, and sound tighter. I love mine too, but this mod seems to make them sound even better. they used the sticky weather strip for around the speaker, and the skinny foam around the backend. better seal, better job the speaker does....
