Why does my brand new Clarion EQS746 1/2 DIN Graphic Equalizer with Built-in Crossover not making any sound

Kindly get in touch on [email protected]

the remote is connected to 12v constant

the prq can be used after a head unit before crossover and amps. it is a preamp/equilizer and you must have an orion amp in the signal chain that uses the 5 pin din plug to provide power to the prq via phantom power. if you have a crossover it must be a brand with the same 5 pin din pinout input and output. the din pinout is 1\+15v, 4\r. ch input, 2\ground, 5\l. ch input, 3\-15v. left to right or clockwise on din. the power can be supplied to the prq with an optional 100 pps power supply unit. rca from head unit feed the input and the 5 pin din is the output .

You can use either the front or the rear, it won't make any difference which one you use.

This answer will require a very detailed technical solution, therefore I recommend contacting a local car audio professional or Clarion customer support directly here:
