im running 4 of them off of a ZRS 9000D
they produce some nasty lows

i am doing high 150s at the kick off of music. if i could just get my deck to stop skipping

it starts skipping like crazy once i hit around 156

anyone looking for a great all around sub these are the subs to buy. especially now that the price has dropped so da*n much on them.

mine are for sale in classifieds if anyone is interested.

the only reason im getting rid of them is to rebuild for this coming season. im going back to 12s looks like ill be running 8 of their new ZRS line of subs
