WOW..were did you get the info on this 504 amp? I looked all over the place but could not find the spec's.

I checked the Ohm's on the speakers..there the same.
The cables are perfect..no shorts or anything,,,work fine.
The problem would be i'm not about to blow up the amp..to see if the speakers have a problem. I could check 1 speaker at a time...but again.. i have to run it till the amp shuts down.

Not my Fav thing to do...as i could blow up the amp doing this.
