Hi I have a peavey 400 watt combo/amp there is a place in the back of the amp thats for hooking up another cab.. its 125 watts at 4 ohms.. I was wondering If I bought an avatar cab. The 4x10 cab. Its 1200 Watts RMS. Would it be alright to hook up to the amp? I thought i knew it would but i read something and now im not sure. If you can help then.. thanks alot I heard about underpowering and i think if i understood right.. it can damage your stuff.
