    Subwoofer/Amplifier and Line Out Converter Help Needed for CTS

    Hello everyone, I'm stuck and need a little help. I recently installed a 15" subwoofer and amplifier in my 2007 CTS, however it is not working properly. I have a secure power source coming from the battery to my amp, a secure ground from my amp to the car, and a remote wire running from my amp to a fuse spot that is powered on with the key. I have searched this forum and found others arguing whether to splice into the stock sub or the rear speakers in order to hook up the line output converter. I chose the rear left and right speakers to splice into. I found online a diagram of the car's stock amplifier with labeled wires, and located the (+) and (-) wires of both the left and right rear speakers. ( I found that the white and tan wires are the (-) and (+) for the left rear and tan and orange are the (+) and (-) of the right rear for anyone who has this quesiton.) So anyways I spliced the positives to positives and negatives to negatives but my sub woofer is hardily working. It acts as if it is not getting enough power and only vibrates? I assume i hooked up the line output incorrectly but I'm lost as to what I did wrong. Any help or suggestions? Is splicing into the stock subwoofer a better idea? How do i do this since it is just one speaker and not a left and right? Thanks in advance, Evan

    Hook the line out converter to the stock sub...the issue is the rear speakers don't get the frequency needed, the sub does.

    you can disregard one set of the wires for the line out converter when hooking up to the sub woofer, just hook up one set.

    Thank you very much, that was my guess but was worried you needed two speakers to properly install the LOC.
