My friend picked up 2 power acoustik mofo 15's before they were trully released. They were a shop demo for a day before he got them, and with a jbl 1200 watt amp running them, they are painfully loud in his 1997 mirage coupe. They definitally hit loud and clear, but when he found out that they were being released under the power acoustik name he told me that he wants to get rid of them though...
