I have two 12" gerlman concept subwoofers. These subs will make you be heard for block, very hard hitting with anything. Its will take a good sized amp to power both of these. But with no matter what size they should perform just fine. If any questions call or text me mon-fri 6-9 or weekends anytime between 9am-9pm. 785-443-5663. thanks for looking. The price is for both subs.
