When I got my 7001 I never broke it in, I ran it full throttle right when I got it , or atleast very high in the rpms. I ordered an 8000 it should be here next wed. I would like to know the proper way to break these bad boys in, and do you actually have to? I ran my 7001 and BCZ2600S like I normally would instead of breaking them in and I think they work fine just wanted to see what you guys had to say. Thanks.
