Q: My Toyota rear speakers stopped working but front speakers are fine — is it the connector?
A: Selective speaker failure (front OK, rear dead) on Toyota audio systems is frequently caused by corrosion on the rear speaker output pins (Pins 9–12) in the 13-pin amplifier connector. Inspect the connector before replacing the amplifier.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
