Hey all, I've got components in the front with separate tweeters and 2 way cross overs in the rear deck all hooked up to a 4 channel amp and 1 sub hooked up to a mono block. My question is are components suppose to put out some bass? I tuned it by ear using Crutchfield website and they said tune it so you don't hear any bass from the fronts if you have a sub, now my sub hits hard n like it should, but some songs the bass sounds real tinny with the speakers... Any way to fix that? Thanks
