I need an amp that would be the best match for my Rockford Punch 1 sub (150RMS, 300Max). I need an amp that will make this thing thump hard in my car, also it is in a ported box. I know that matching RMS to RMS is the best, but most amps are over rated and the RMS and Max are not the real RMS and Max because they were tested on a 14.4V system.

Thanks in advance
