so i went into a local car audio shop today and ordered myself a dd audio 3500 12 inch sub. im going to be replacing my kicker 15 inch l7. now i know its obviously gonna sound better than the kicker...but will it be just as good in terms of spl? loudness? its going to be powered by a kicker dx 1000 watt amp. same thing i powered my l7 with. so im pretty excited about it but im just curious about those little things. plus will it be able to hit high and low basses good to? its going to be in a ported box but im not sure how big.
