I am a complete greenback when it comes to the issue of matching an amp head with a cabinet(s). I am terrified that by making some silly little mistake I will destroy some expensive speakers. But, alas, it is time to upgrade to a bigger setup. Here are my questions: 1) If you are running only ONE cabinet, does it have to be at least the same wattage as the head? (assuming the ohms are the same). Will a 400w(8 ohm) head will require a minimum of a 400w(8 ohm) cabinet?? AND a 400w(8 ohm) head will FRY a 300w(8 ohm) cabinet?? Or will this only happen if it is driven at very high volumes?? 2) If you run TWO cabinets out of one head, what are the amperages meant to be? Question: A 400w(8 ohm) head will drive a) TWO 200w(4 ohm cabs)?? b) TWO 400w(4 ohm cabs)?? c) TWO 200w(8 ohm cabs)?? d) None of the above!!!! Please help me out if you can.Thanks!!
