Oh I forgot that you already had a crunch huh? Well just from what I hear, people seem to think crunch is pretty low end. I think Crunch can deliver bass, but not clarity. Like most people say the cheaper amps can't give you really solid, punchy bass. Like if you listen to really fast beats that just keep hitting, and you like a sound quality system, then you probably need better than a crunch. But I guess just for bass, crunch is decent. Are you sure you can't keep your current crunch with those new cerwin vega subs? Maybe you should try that out first, see how it sounds, etc. To be honest, I'm REALLY tempted to get that 800 watt crunch amp you're considering. I mean, for 120 bucks, even if it does half that, I'd be happy. Damnn but I really told myself I'd only get RF or PPI next time. Let me know if you get it, I'd like to hear it...
