I have the following two cabinets: Hartke VX115 - 300 watts @ 8 ohms Hartke VX410 - 400 watts @ 8 ohms I have the following head: Hartke HA-3000 - 180 watts into 8 ohms The Samash guy said this should not be a problem, but after reading some replies to another post, I am beginning to wonder about that. I read some articles saying that more bass amps are blown by "underdriving" than by "overdriving". I want to stay with Hartke, so which amp should I get to properly drive these cabs or is this OK? Thanks in advance!!
