Also agree with Racamuti.
Simple test to check for the proper polarity hook-up of your speakers. Disconnect the speaker cables from the Power Amp.
Take a D cell battery and momentarily connect one speaker cable wire to the positive side of the battery and the other wire to the negative side of the battery. The correct polarity will cause the speaker cones to move forward. The wrong polarity will cause the speaker cone to pull inward.
