to get a signal going to my Power Acoustik Amp(980watts) i used a line output converter getting signal from my sub on nmy 03' a4 with bose....it gets signal to my amp fine BUT it seems that the amp will only run one sub of my 2 12"s....i tried running wires from the stock sub into both the L and R input of the line out converter but still only one of my subs will work....what do i do? i was thining about trying to tap a signal from the bose amp instead of trying to get both L and R signals form the sub....but i have no idea which wires to tap on the amp.....please help

It sounds like you're trying to install it between the stock sub wiring and your new amp. The LOC should be installed between the head unit and your new amp. If you install the LOC after the stock sub amp you might be overdriving the LOC. The problem of only being able to run one sub goes back to your other question about the wiring of the subs. Your amp may not be able to handle the load you're giving it.
