My setup is a AudioMobile LDS-2 to take the signal from the rear speakers to the amp for my sub. This lds2 also supplies a power trigger wire to the amp to turn on the amp once it receives a audio signal.
This all worked up until yesterday when I installed a kenwood 4 channel amp behind my head unit, now the sub seems to require a high volume in order to turn on. Why is this? If anything the signal back there should be amplified even more, so why would this happen?
Does anyone know anything I can do to get the sub to turn on with a lower volume?
