box tuning, if I were to use a box around 5ftcubed and tuned to 32 hz, even though manufacture recommends 40 (i assume its recommending 40 at 5000 watts, im only putting 2000 in,

would that be alright, being in my first set up would I even notice a difference?

manufacture for a new version of my sub i couldnt find for my exact sub, same size and output though

5 Cubic Foot Optimum Enclosure: Vented 40Hz - (2) 5" round x 9.5" deep or slotted 10" x 5" x 9.5" 50Hz - (2) 8" round x 7"

just for a daily, i dont intended on competing, i mean I wish I could but I dont think 2000 watts is enough to compete
