3Sixty.2 With dd-1

[seminolesubking]

Hey,

I have a stock headunit in my malibu maxx. I have the speaker level going into the 3sixty.2 and then i am using the rca outs on the 3sixty to my highs amp and sub amp. my question is how do i use the dd-1 with the 3sixty.2 properly (since the 3sixty has gain like adjustments on it also)?

Thanks Guys
