my friend got a new car and had no room for his subs and amp so he gave them to me.he gave me 2 Infinity 1230w 12" subs and 1 MTX Thunder421D amp. one of the subs has some wiring problem so im just going to throw it out and was wondering since im going to have 1 amp and 1 sub if i should get 2 completely new subs or just get another Infinity?
