I got the sub for 270 shipped and paid 300 for the amp.. Sub used .. About 10-12 hours.. Amp used the same.. Retail is.. 500 on the amp i believe.. So totally i have about $570 invested.. I dont need the money, and i might be able to sucker some young kid for 800 in the summer time.. All they have to do is hear it.. And they usually think it's more than what it is
