Hey my bro just sold his car and didn't have room in his new truck to fit his 3 phoenix golds tantaum 12d's so he gave them to me. I'm still kinda new to car systems and everything and was wondering if anyone could tell how these subs are any good, and what kind of amp i should hook up to them. He only had an diamond audio 300 watt amp pushing them before. My price range for an amp is 250. Thanks!
