I am going to power up zones 2 & 3 with a separate receiver/amp and have the following at my disposal: JBL MPX300 power amp (Tons of power - no pre amp features), a NAD 3300 (vintage 1989 - very clean) and an HK 25 loads of effects. I don't really know how to hook up the MPX 300 but I know it's used by DJ's for huge power; should I use a receiver with various features or try to use the power amp and control the 2 zones via the V2400? I plan on using the presence soon, but need to get the speakers 1st. Please, any adice would be a help
