MONO AMPLIFIER - APPLICATIONS INPUT CONNECTIONS * This amplifier has RCA connections for low level inputs. Low level signal is carried through RCA cables. it is preferred to use low level inputs to the amplifier if the head unit is equipped with the low level outputs. SPEAKER OUTPUT CONNECTIONS You do not need to make any adjustment for the input connection of amplifier before you connect the speaker output. * Connect subwoofer wire to corresponding speaker output terminals of the amplifier. * Be sure to have the positive wire from the speaker to the positive speaker terminal of the amplifier and the negative wire from the speaker must connect with the speaker terminal of the amplifier. Reversing any of these connections will result in the speaker cones moving out of phase which causes bass cancellation. LEVEL CONTROLS Turn the VOLUM E control on the amplifier to Min initially. Once the initi al power sequence has been performed, set the CD/ RADIO volume control to roughly 80% of full. Insert a CD or tune to a radio station and slowly turn up the amplifier VOLUME control until you hear some distortion , and then back it off for clean sound.
