8V and 17V DC to the amplifier. If the supply voltage is outside
of this range, correct the condition before attempting to power

phones are capable of reaching higher levels of audio output
when Bluetooth streaming or connecting by auxiliary input.
If you feel that the product is not loud enough, check your
phone settings to see if any adjustments can be made to im-
prove audio performance, or try using a different audio source
or Bluetooth streaming device to determine if performance
improves.

distortion can be heard if the vehicle charging system is below
+12V.

in-line to turn the audio system on/off.
• Check that +12V and GND connections are properly con-
nected
• Check if the fuse on the +12V wire located near the battery is
blown; if so, replace it with an identical fuse.
