I will take pics tonight - the model is prs x720,
This is the info from pioneers website - this amp is very under rated, it is probably pushing more like 750 watts rms X1 at 4 ohms....
Talk about well-balanced: the 400-Watt PRS-X720 is both a sonic weapon of destruction and a fine musical instrument, capable of reproducing bombshell rock one moment and delicate classical the next. The built-in variable crossover and variable bass boost add to its flexibility, as does its bridgeable 1/2/3-channel capability. Terminals, inputs, and outputs are gold-plated, adding to the sonic purity. The PRS-X720 carries the Premier two-year warranty.
