I just got my two alpine type r 12 two ohm subs and my custom ported box specified to their specs. I would like help on picking out a amp for them. I dont have an unlimited budget but am willing to spend the money to get a amp that will last and is a good fit with these subs. also i need to buy a capacitator... any suggestions on which one to get? im totally new to car audio and dont know much about it so any help, suggestions, personal experiences are very much appreciated thanks
