Hi guys, question. I got an LH500 head. Hartke's site said that it runs at 4 ohms. The music store I got it from had two cabs hooked up to it, and I had a long discussion with the bass guy there, and he told me that one 4 ohm cab would be ok for it, and would give me the total 500 watts. Well, I order a cab from Avatar, and when it comes in, I finally open my head. I look at the back for the connections, and it has two 8 ohm outputs. Now, am I running it at 500 watts and it will work, or am I risking melting my cones? The thing that aggravates me is that everyone told me it would be ok. Please help me guys. Thanks!
