This person does not know what he is talking about.second one is for a second amp, don't have to plug anything into it.
Ah, I thought you meant you had two sets of sub outs, your sub amp should have stereo inputs, and only using one will cause you to only have sound from a single channel, which means you will only get certain parts of the music. If your amp only has a single channel sub in, you can use a 2 into 1 RCA adapter to make sure you get all of the sound.my head unit has 6 total rca outs. left front, right front, left rear, right rear and then 2 designates dub outs. i just didnt get why it would have 2 for subwoofers unless you have 2 seperate amps running on their own.
couldnt i just use a a pair of rcas as in a 2 chennel set of rcas? and connect both ends on my head unit and both ends to the stereo input and be good to go?Ah, I thought you meant you had two sets of sub outs, your sub amp should have stereo inputs, and only using one will cause you to only have sound from a single channel, which means you will only get certain parts of the music.
