    RCA outs on HU and which amp goes where///

    Im hooking up two amps...one for my subs and the other for my front components and rear speakers. The back of my HU has 3 rca aouts (front rear and sub). Should I run the 4 channel amp out the rca out labeled front? Or should It be rear? Should I run the sub amp to the sub RCA out or chain it from the 4 channel amps 'sum output' RCA? Im confused as to which amps to hook up to which RCAs coming off the HU.

    THANKS!

    Here's what I would do:

    -4 ch amp: designate 2 channels for front and 2 channels for rear.
    -Hook the front pre-outs up to two channels on the 4 ch amp.
    -Hook the rear pre-outs to the other 2 channels on the 4 ch amp
    -Make sure your speaker wire connects to the right terminal on the amp for each speaker location.

    -Mono amp: Hook the sub pre-outs to this

    By doing this, you can utilize your HU's bells and whistles like sub control, LPF, HPF, and creating different frequencies in all the drivers.

    ^^^

    x2

    That way isn't the only way to do it but it is the method that makes the most sense (and the way your head unit is designed to be utilized ~ is why it has three sets of preouts with one being a dedicated subwoofer output)
