Vibe STEREO2-V1, Instruction Manual, Page: 10 / 16

Trouble shooting
● Before removing the amplifier, refer to the list below and follow the suggested procedures.
● Always test the speakers and confirm that they are wired correctly first.
● If in any doubt get help from a qualified auto electrician.
Amplifier Will Not Power Up
✓ Check for good ground connections. Ensure Ground cable is connected directly to bare metal and not a painted
surface.
✓ Using a multimeter check that remote terminal has at least 7V DC.
✓ Using a multimeter check that there is battery voltage of at least 10.5v DC on the positive terminal.
✓ Check all fuses.
✓ Check that the protection light is not illuminated. If it is lit, shut off the amplifier by disconnecting for thirty seconds and
then turning it back on.
Protection LED Illuminates When Amplifier Is Powered Up
✓ Check for shorts on all speakers wires. (i.e. no speaker wires should be joined together and no speaker wires should
be touching the cars chassis)
● The amplifier is designed to shut down automatically when the units temperature goes above 80 degrees. If the
amplifier feels very hot then this may be the reason for the amplifier not starting. Allow to cool down try again.
●
Remove the speaker wires and reset the amplifier. If the Protection LED still comes on then the amplifier is faulty. This
damage may have been caused by either failure to follow these setup guidelines or abuse.
Amplifier Gets Very Hot
✓ Check the minimum speaker impedance for the amplifier is correct.
✓ Check for shorts on all speakers wires. (i.e. no speaker wires should be joined together and no speaker wires should
be touching the cars chassis)
✓
Check that there is good airflow around the amplifier. In some applications an external fan may be required.
Blown Fuse(s)
✓ Check both positive supply and ground for shorts.
✓ Check that the positive wire is connected to the positive terminal on the amplifier.
✓ Check that the negative wire is connected to the ground terminal on the amplifier.
✓ Ensure that the correct rated fuse is fitted:
The VIBE Stereo 2 amplifier uses 1 x 30 amp fuse
The VIBE Stereo 4 amplifier uses 2 x 25 amp fuse
Distorted Sound
✓
Check the gain control is not set too high. If the speakers sound distorted turn down the gain until the
sound is clear.
✓
Check that all crossover frequencies are correct. See Setup section for more details.
✓
Check for shorts on all speaker wires.
✓ Check all speakers are wired correctly. With the correct polarity being observed on each connection.
