Nope had American Bass in it from day 1. I started out with some cheap ass subs. D4 subs....8 subs on 2 amps....and that was still risky being 150 watt subs was just to get it playing.Saw this in augusta. I thought you were running hifonics then?
Each sub is in it's own sealed chamber....seems right so if I loose a sub it wont kill the rest of the build. It works I can drop any 1 sub and loose less then 2db but it will keep playing with out any problems.
Sealed is 2 cubes per. aprox
Ported is aprox 46-48 cubes
My loudest has been around 480sq inchs of port....much less then I built this for.
