Pretty good box overall, port area is a little small if you run high powered subs or listen to music centered around 30hz. About the best you can do with a underseat box without getting into seat lifts. 2 sundown E10s on 1200 watts absolutely hammers 35hz and up!
ANYONE WITH A FORD WITH B&O system run a kicker keyloc or Nav Tv to get real low end to your sub amps!!!
