From what I understand, at times yes, and at times you're going to clip your amp
Box Rise included, different notes changes the impedence reaching your amp, and IIRC the Kicker is rated for 2ohms, on those occaisions when box rise doesnt make up for that lower ohm rating, your amp is going to clip/get hot/not like you
SOMEONE who has more knowledge enlighten him, because I'm not sure I'm right.
Use my statements as a starting point for someone new, people tend to talk more if they get the chance to prove someone wrong, dont use what I said as facts until someone verifies
