Pre amp line driver

[r.sok]

Am I supposed to mount it closest to my h/u and then do my rca run or after the long run of rcas and mount it near the amp

Close to your H/U

I have a question. I have an eq/line driver with a master volume on it. Do I match my amps gains to the head unit of eq? If so do I max the volume on the eq and then set the head unit volume to 3/4 an set the gains from there?

no. The 3/4 volume rule you see on yahoo answers and some other sites found on google is not what you should go by at all, ever.You use a tool that can detect distortion in an analog signal, measure the signal of your HU to find maximum distortion-free volume, then connect HU to EQ and adjust EQ output until you reach max distortion-free (unless the voltage goes higher than your amps max input voltage, in which case, back it down to that voltage), and then connect output of EQ to amp, and match amp gain to input voltage/measure the signal as you turn it up and stop when you see distortion. an O-Scope or DD-1 would be the tool you want to use for this.

Thanks for the info! I knew the 3/4 rule wasn't the best way to do it but at the moment I don't have an o scope. Thanks again!
