YES

Reverse the left and right inputs.

Check the pre-amp (RCA/Mini-Din) cables for open connections and make
corrections. Did you find open connections?

NO

You’re done

SOUND IS NOW IN...

Opposite Channel

Problem is in the speaker or speaker
wire of the silent channel. Check
speaker leads for pinched, shorted, or
open connections.

Check speaker cables for shorts. Check for
excessively low speaker  impedance.  Fixed?

YES

NO

You’re done

Check voltage supply to ensure sufficient voltage is
being delivered. Is amp getting enough air to cool
off? Did that solve the problem?

YES

You’re done

NO

I

f using passive crossovers, are the

connections correct?

YES

NO

Same Channel

Problem is further up the signal path.
Reconnect RCA’s to amp as normal.
Reverse RCA inputs at crossover.

SOUND IS NOW IN...

Opposite Channel

Problem is in the crossover. Contact
your dealer.

Same Channel

Reverse RCA outouts of head unit

SOUND IS NOW IN...

Opposite Channel

Problem is in the RCA cables.

Same Channel

Problem is in the head unit

Voltage at amp may be
dropping below minimum
limits.

Power output of amp may exceed
power handling of parts. Upgrade as
needed.
