What are ya'lls opinion on an amp for two type r 12's, they are both dual 4ohm so I would wire them down to 1 ohm. I have them in a probox super bass box. I have a planet audio amp 1500 watt right now thats pushing 1,000 watt rms at 1 ohm right now and I'm not really happy with it. I don't really wanna spend over $300 if possible. Thanks guys.
