Questions and answers
Kenwood kac 7252 blows fuse immediately after start up, eliminated external issues so issue is internal on amp, whst should I look for internally to fix?
If a Kenwood KAC-7202 amplifier blows a fuse immediately after startup, check the following internal issues:
1. Incorrect wiring – Ensure the subwoofer impedance matches the amp's supported load. Wiring dual voice coils to 1 ohm when the amp does not support it can cause overload.
2. Polarity issues – Incorrect speaker polarity can stress the amp.
3. Short circuits – Inspect for shorts in speaker wires, power wire, or inside the amp.
4. Ground connection – Confirm the ground wire is securely connected to a clean, bare metal part of the chassis.
5. Fuse rating – Use a fuse with the correct capacity, equal to or slightly above the unit’s fuse rating.
6. Internal component failure – Blown internal components like transistors or capacitors can cause immediate fuse failure.
Check all wiring and connections before assuming internal damage.
