Can we connect speakers with A/B dual inputs to a single-output amplifier? Thanks in advance. Eric

    There are speakers with two pairs +/_. Left speaker A +/_ and B+/_; Right speaker A+/_ and B+/_, so 4 wires per speaker. My old amplifier had four outputs for my 2 speakers, but the one I have now has only two: Left speaker +/_ and Right speaker +/_. Would it be possible to parallel A+B on the speakers? Thanks in advance.

    Hello,
    Unless I’m mistaken, the amplifier is designed for 8-ohm speakers.
    What is the impedance of your speakers?
    If the impedance is the same value, wiring in series doubles the impedance, wiring in parallel halves it.
    So be careful not to go below 8 ohms.

    According to the label on my speakers: high impedance 6 ohm, low 8 ohm. High power 60 W and low 120 W for music.
    Brand Technics SB-EH 590.
    Thanks in advance.

      I therefore invite you to perform a series wiring montage
      Output of the amp R+ to the right speaker in A+, A- connected to B+, B- connected to the amp in R-
      Output of the amp L+ to the left speaker in A+, A- connected to B+, B- connected to the amp in L-
