2 12" Rockford Punch IIs in a brand new store bought double box and a Pioneer 760 watt amp used lightly for about a year with some monster cable for $300. It all looks good, he said it's hardley been used for about a year (can trust him, friend of mine) Also, he said if it doesn't work he'll give me my $ back, and like I said, he's trustworthy. Problem is, I know nothing about stereo stuff as far as value goes. Is it a good deal?
