well if you are running it at 2 ohms stereo than you are fine, but that also means that it is not bridged,
bridged is when you take the Left positive and Right negative speaker outputs terminals to your drivers!!!, ( Mono)
Stereo is just Left positive and negative to one speaker, and Right positive and negative to another!! (Stereo)
double check your load Dex, and tell me if it is either bridged or stereo, can only be one or the other!!,
as for the epicenter, i would use it if you want the extra thump, thats what it does, it doubles the decibel level of the signal for each ocatave that it goes down... for example middle C' on a piano, is at 0db's , then if you go down to the next lower C, it would be +3db's of signal (bass) increase!!
And you should only have the line voltage set at 2 volts, unless your cd player is an upper end model and puts out 4 volts, or even if you have the epicenter you have is a line driver as well and i generates 8 volts but other than that lower the line level voltage on the amp!!!! , all of these suggestions will greatly vasten the life of your amp and the over all sound quality!! trust me!!!
