Right now Im running 3.6cu at 32hz in the trunk of my 01 mustang but once I upgraded to dc lvl 4s my box has been shredded and rattles really bad so its rebuild time. Im looking for similar tuning, maybe a little higher like 34 or something with similar airspace, but I cant decide I want a single 6" aero forward ported,slot port it through the deck, or a slot side port? definitely going to double baffle this time.
