Installation Tip
(Please take your time to read this before performing installation)
1. Before removing OEM head unit, confirm that the fader, balance, bass and treble levels are at
the center/neutral or “0”on the OEM head unit. If this is not performed correctly, you may have
problem with the volume or the fader during or after the installation.
2. Before removing OEM head unit, set the volume on the OEM head unit at 50%. If this is not
performed correctly, you may experience weak sound, no sound or distortion after the
installation.
3. The factory amplifier memorizes the fader, balance and volume set up. Please set up according
to above recommendations before removing the OEM head unit.
Trouble Shooting –No Sound
Step 1 :Follow the above recommendations.
Step2: Please make sure ALL OEM connectors and Beat-Sonic connectors are securely connected. If
something’s not connected, something will not work.
Step3 : Please make sure the speaker wires on the Beat-Sonic sound module are connected to the
aftermarket high-level speakers wires accordingly to the instruction. (Please do not use the RCA cables)
If there are only Front L & R speaker wires on the Beat-Sonic sound module, please make sure that it’s
only connected to Front Left & Front Right only. Most Lexus models are equipped with the 2 channel
amplifier, and you can only connect two speaker wires. Beat-Sonic sound module will distribute sounds
evenly throughout all speakers just by connecting front left and front right speaker wires as suggested.
Step4 : Test factory amplifier and speakers by using the OEM head unit. If there’s no sound with the
OEM head unit, either the amplifier or the speakers are malfunctioning.
Step5 : Check fader on the OEM head unit, and make sure it’s at the center/neutral or “0”.
Step6 : Check the fuse.
It is very easy to miss and not connect one or more connectors during installation. Please take your time
and check if all connectors are securely connected, before reinstalling all your dash panels.
