I don't know what i want. I am looking for something to save on space. I want it to sound good, and be able to punch a little, like I said I don't want to be one of those people driving down the road rattling the cars they pass becuase of their powerful bass, but I want enough power that I can hear and feel the bass over road noise when going 70 miles per hour. I used to have a Jeep wrangler with a couple of RF 10" subs I think, not sure exactly which ones. They were powered by a RF Punch 150a, I think. The amp cost me like 250.00 at best buy about 3 years ago. Those sounded good enough, but took up more space then I would have liked. I would trade some( and by some I don't mean a lot) of thump in order to save the space.
