Hey guys Im trying to add a subwoofer and amp to my truck and I hooked up my line out converter to the factory harness thats going to the stock bose amp on the back wall but when I plug my amp in and go to a song nothing is coming out of the subwoofers but If i plug my phone directly into the amp they will play. I was wondering what are the wires that I should use or if there is another way I have to do this here is a pic of what I have done and isnt working

I used:

green / green black
white /blue, black

for the wires for speakers wires as for thats what I read to use but for some reason its not working for me!

You'll need to tap into the subwoofer output. You're tapped into the front outputs. The amp has already filtered them through the high pass crossover built in, so you're not getting any sub frequencies out of them. The sub outputs are as follows: Subwoofer (+) BLUE\GRAY PIN 1

Subwoofer (-) GRAY\BLACK PIN 5

Located in the black connector on the far right of the amp in your picture.

Thank you! I happened to figure that out on my own that night! my SLE truck those wires worked fine and on my new SLT truck they didnt do anything!

Hate to being up an old thread, but my line convertor has 2 sets of wires going in. It has a single RCA out, do I HAVE to hook up both sets of wires or will 2 work? Tapping into a 2015 with bose amp
