fastfreight, thanks for responding.
with 2 subs, don't you twist both the red and yellow together, connect to positive speaker left or right, and either float the negative or ground the negative on the chassis for each sub?
you threw me a curveball with yellow being taped. i was mostly confused about the negative and idf you floated or grounded on chassis( and which screw you used
thanks for your time
