I was wondering if someone can answer this question for me. I have 2 "Mesa Powerhouse" speaker botoms, 1 is a 2x10 and the other is a 1x15. The 2x10 is rated at 600 watts @8 ohm and the 1x15 is rated at 300 watts @ 8 ohm. My amp is the "Genz Benz Shuttle 6.0". The amp is rated at 600 watts @ 4 ohms. When I connect both speakers to the shuttle can I damage the 1x15 being that i'm pushing 600 watts into a 300 watt cabinet? Or..... am I losing any power being that 1 cabinet is rated at 600 watts and the other at 300 watts. Thanks !!
