Regarding Outlaw PCA's. They look great and provide great sound. I ordered the 7 pack so I has 2 left over...Good Thing...When I initially set up the amp all the channels were fine except for the surround left so I double checked the wiring and made sure that the pca's were connected properly..well after trying for about a half hour I just took one of the 2 pca's I didn't use to see if that was the issue. Turns out that was it...just hapenned to get a bad pca. Better that than having to thesend 990 or 7125 back.
