Is it possible to run an aftermarket EQ with a line output converter?

I have a ‘13 volt. The factory head unit runs to the LC7i, which then runs to the 5 channel amp. Is there a way to add an EQ to this setup? I have a Massive Audio EQ7X

If you are only using 1 pair of rca outputs from the lc7i to the 5 channel amplifier, then adding the eq would be easy. Output of lc7i to input on eq, output of eq to the amplifier.

theres 3 pairs of RCA running from the LC7i. The main outputs, the channel 2 outputs, and the channel 3 outputs each have a pair of RCA running to the Line In RCA on the Amp

That eq only has one pair of inputs.
If you want eq it may be easier to go with the LCQ-1 instead of the lc7i
