i have a acura tl and i am wiring a line out converter to the rear stock subwoofer wires..

there is 4 wires on the converter.. do i wire them all to the two wires on the stock sub? if not, how would i install this?

 

Why are you running an LOC to the stock subwoofer wires? Just curious. Usually you run it to either the front or rear speakers and then you have your RCAs that run to the amp.

 

because my headunit has a "subwoofer" adjustment and if i run the loc off the stock sub i will be able to control all the subwoofers through the headunit

 

Well just wire up the left side or the right side and get a splitter so that the one channel feeds into both RCA inputs on the amp. Or you could try it with just one RCA first and see what happens, but your amp will have two RCA inputs.
