    i know the deck has a good eq built in but when driving at times it would be great to have treble control at my fingertips from time to time .

    so im looking at installing Clarion EQS755 equalizer.

    problem is how would you connect this ?

    the eq has
    main in and aux in
    so from my deck what line would i use to go to the main in on the eq

    front pre outs or
    rear pre outs
    sub pre outs

    my setup i have 2 amps , 1, 4 channel amp for my fronts and rears
    1,mono amp for the sub

    off my deck now i am useing front,rear rca preouts to the 4 channel amp
    and the sub out for my mono amp

    so i just connect the front out rca off the hu to the eq input
    then run the 2 sets of rca to my 4 channel amp , front out and rear out. and leave the rear preouts disconnected on the back of the hu deck correct ?

    also hoping i could make use of the sub volume on the eq and do away with my inline sub volume knob

    would this be possible ?

    yeah, you would use the front rca out of the headunit to the main in of the eq, it splits it up for you into the Fr, Rr, and SW

    no, you simply run the sub out to your subwoofer amp, the eq will split up the input signal

    yes the eq only needs the main input, it will do the splitting up within, therefore giving you control through the eq

    ok thanks , guess for some reason im thinking i wont get as much base output useing front out from hu to the eq
    as i would useing sub out from the hu direct to my sub amp.

    but i do want to make use of the base volume knob on the eq.

    well, you won't have less output with the bass, but imo the built in eq of the headunit is better and what I would use personally, if it's bass volume adjustment you are after, I'd add a bass control knob and ditch that eq........
