dont get me wrong i started with kickers subs i even had the 2004 & 06 & 08 & 11 models but i think is time to go with round now lol i really like FI AUDIO now those SP4 look very nice
just asking cause kicker went down on quality i remember my two 2002 kicker l7 15s hit harder than my current two 2011 l7 15s they dont make them how they use to
