how much would a used alpine amp and 2 twelve inche alpine subwoofers be worth? its about 3 years old. thanks ( would it be worth 250 bucks ??

 

How much was the stuff new?
If they're in good/excellent shape, expect about 1/2 of new price for the amp, and 1/3 of new price for the subs. anything more than that, and consider yourself lucky.

If they're beat up or show much wear, expect the price to go down with condition.
