  • Kenwood amp question

    Hi, I just bought a Kenwood KAC-719 subwoofer amp off ebay and it came with no instructions.

    For inputs it has two phonos for line level input and 2 inputs for speaker level input, I want to connect the amp to the subwoofer output from a 5.1 soundcard, but am not sure whether i need to connect it to both rca inputs. I am making my own phono to 3.5mm cable, so i can have the subwoofer out split into 2 rcas.

    The second question i have is about the subwoofer out connections, it has four screw terminals, the middle 2 have "speaker out" and + & - printed above, the outer 2 have the greek letter sigma then servo II, does anyone know if these connections are connected in parallel with the others allowing 2 subs (or a DVC sub) to be connected in parallel?

    Hope this is reasonably clear, and thanks in advance for your help

    It would help A LOT if you posted some pics. Don't want to say anything, 'cause I'm not sure what you are talking about. The general rule for bridging the outputs of an amp is to hook the + wire from the sub to the + of one channel, and the - wire from the sub to the - from the other channel. Ussually they're not the middle peaker outputs. The amp has to have RCA(Cinch) inputs. Now, some amps have low level inputs, and hi level inputs. Don't connect them both at one time. Use a wire that has 2 RCA's, that go into the amp, and a jack for your soundcard. (that's if it has jacks)

      Sigma servo II is a kenwood thing, deals with running the amp in TRI mode, 2 regular speakers with one sub wire up togeather. You can download the manual PDF at kenwoods site. Also, most of their amp are similar in connecting so If you cannot find documentation, find an amp that is as similar as possible.

        Basically i was surprised to see that it had 2 rca channel input as it is a mono amp.

        Thanks for the help

          All mono subs have 2 RCA inputs.
