Phase inverted preamps and Rel Subwoofers.

I have come to realize that my preamp is a “phase inverted” preamp.  This basically means that most recordings will sound better when you reverse the positive and negative wires on the back of your speaker terminals.  Since doing this my amp is getting hot.  I have Rel subs hooked to the terminals of the amp the normal way.  Could this cause the heat? Should or (can I) reverse the subs positive and negative positions on the (amp) along with the the speaker wires as well?  In this case the speakers positive and negative would be changed back the traditional way.

I know how to phase my subwoofers.  This is in regards to the mains.  The subwoofer set up was  in question due to the heat I am experiencing -which is likely not the cause based on some of this feedback.  I switched the speaker polarity back and am still experiencing heat so not sure at this point.

@erik_squires Thanks Eric.  I checked and they are in place.  I will just need to disconnect the subs for a period of time and check that next.

Sub inputs should be too high an impedance to cause the amp additional stress.

What’s your amp? Is it running in Class A? Is the bias set too high?

It’s a Modwright KWA SE.  It has a high bias and low bias switch.  I have it set on high bias.
