Save your money on this. Had this sub for about 7 months and only had it installed for about 4 months and the voice coil went bad on it had everything professionally installed all gains and crossovers set correctly just stopped playing one day. All products were bought from this website, I contacted customer support about it and they said they only have a 90 day warranty so there was nothing to be done. Would not recommend this subwoofer. There are other companies out there that offer 1 to 2 year warranty and stand behind their products.
