I'm looking into purchasing an alpine swr-12d4 but want an amp that would be able to power 2 type rs if I decide to get another in the future (would recommend it be able to run my existing 4gsuge wires)? List a couple options if you want! I don't wanna break the bank but want people to hear me coming from a mile away! What alpine related system are you running?
