Complete in install review

[asmithey]

After many discussions, on forums, here is what I have boiled down my install to, four options. I am seeking guidance for the most accurate set up. If you have any input, please let me know. Thanks for all of your help. I also have an extra set of tweets, if anyone thinks they could be beneficial somewhere in the set up.

see images above.

set up 4:

I am leaning towards set up 4.

I am posting some images of my eq/ crossover as well. There is a "LOW" parameter that I am not sure of it's function as to what speakers it affects. Does it just affect the rear "mid bass" frequencies? The manual really does not elaborate too much.

Thanks,
