    Good amp. Powers my 12 nicely. I had a 12 and 10 hooked up and had plenty power for that. I’m sure it would push two 12’s

    I bought the kicker to go with my shallow mount dual kicker 10" subwoofers. The sound is amazing for such a small box. You can't go wrong. great product that really bumps!!
