its all in the skill of the box builder/installer, you need the correct amount of air space and porting.even though kicker has specs they reccomend for thier subs i would never follow them.my box is the shit built by a true pro who basically works with only kicker products.all i can say is this little 10 will stomp systems with 2 or 3 15's even cars with L7 12's if i want to,or sound more realistic and crisp and thats how i like it.
ive had alot of systems in my 30 years on this planet and im sticking to this, this little square freak of a sub is freakin awesome
