I have a MTX three sub woofer box rated at 4 ohms. I wanted to wire them to 2 ohms, unfortunately they are 12 ohms woofers wired in parallel. My question is what is the best amp to get in a $300 - $400 budget. I want something with at least 750 watts RMS because my box is rated 750 rms. any suggestions will be very appreciated thank You All
