I just got a rc 300 fsport non mark levision system and visited my local stereo shop. He said since it has anc and asc he doesn't want to touch it cause the anc will cause feedback in the sub and he can't find any info on how to bypass it and doesn't want to spend 25 hours figuring it out. After looking on the net and crutchfield with no luck has anyone found a bypass to this problem?
