FS: alpine subs, box and amp

i’m trying to sell my one neon and the kid that wants to buy it doesnt have enough cash so he wanted to trade or sell his system. i dont want it so if anyone is interested it would help me out.
he says they are
2-12" alpine type s subs in a sealed box
and a 600w alpine amp
and he said they are only 3 months old and costs around $1000 new
anyone interested?
