trying to setup my line driver

I have a Kenwood deck with 2v outputs
And I bought a hifonics hfeq (4 band eq/line driver) with 9v output.
Amps are mb quart onx4.125 for the highs and hifonics bxi2608 amp for bass.

My question is how do I properly set the gain for the hfeq input and set the output gain to match?

There has never been an automotive audio amplifier built that would not max out with 2 volts of input.  Who said you needed a line driver?

Well its a 4band eq with a built in line driver
But it also keeps my gains down on the amplifier and not use as much voltage.

But I'm just wanting to setup the hfeq input levels the proper way so there's no distortion

1. Turn gains on amps and EQ all the way down.
2.  Wear hearing protection
3.  Start car and turn on system.  Turn all tone controls and EQ controls to flat, turn off any loudness or other DSp control
4.  Play a 1500Hz test tone in your CD player
5.  Turn up volume on head unit to about 80% of full or until you hear the beginning of clipping (the tone changes.)  Set the volume to just before the sound of clipping begins or 80% if no clipping.
6.  Turn the output on the EQ to max.  Turn up the input gain slowly until you hear the onset of clipping again.  Back it off until the clipping sound clears.
7.  Adjust the gain on your amplifier the same way: turn it up until you hear the onset of clipping, then back it off until it clears.
8.  Turn the head unit volume down to zero.  Insert a music CD that you like listening to.  Turn up head unit volume to your normal listening levels.  If you detect any clipping or distortion, turn the EQ input gain DOWN until it sounds better.  Leave it there.

Got it thanx!!
I heard there's a way to do this with a dmm for more accuracy.. do I just take the voltages of rca and match with eq outputs?

There is no way to detect line level clipping with a DMM.
