How well do these subs handle daily?  I have around 2.7-2.9cuft NET MAX to work with (after port).  What frequency do they like to be tuned to?  I would like to daily beat and do comps so 38-40hz, or preferrebly lower?  I would probably run 1000-1100wrms daily and 3000 for comps (a memphis mcd1000.1 and a sundown 3000.1) with a second battery, big 3, and 130amp alt (factory 90amp). cliffs. box size tuning port size daily good/bad? what do u guys think?
