My friend and I are constantly getting blamed for our music distorting at high volumes at parties we host. Without having to invest in new equipment, is there a particular setup that will reduce the load on an amp and allow it to perform at higher volumes for longer? We usually have 2 amplifiers and substitute them when one gets hot and starts distorting, which is annoying. Between us we have 4 floorstanding speakers, each with an impedance of 4-8 Ohms. The main amplifier has four channels, and we are wondering if there is a specific way of wiring up the speakers in a way to reduce the load on the amplifier? The amplifier isn't hugely powerful, around 80w I think. Thanks!
