"Regarding the Y splitter - unless the sub's dual voice coils are not wired together (unlikely unless you buy a DIY driver like the Tempest), there is no difference in sound. Adding a Y splitter doubles the voltage and it adds 3 dB in volume and - yes - helps with sleepy auto-on circuits. If Velo recommends it then go for it."
Your new subwoofer is equipped with speaker-level and line-level inputs. Use the LINE LEVEL jacks when connecting your subwoofer to a pre-amp, signal processor, integrated receiver, line-level crossover, or receiver with pre-amp level outputs. These devices will often have a Low Frequency Effects (LFE) jack which is dedicated for subwoofer use. When using the line level jacks, some receivers may not provide enough signal to have the unit’s auto-on feature operate properly. Additionally, this lack of signal may also cause the subwoofer to produce less output than it is capable of. To alleviate this condition, we recommend the following steps:
1) If using line level jacks, BOTH THE LEFT AND RIGHT INPUT SHOULD ALWAYS BE USED – never use just the left or just the right input. If the subwoofer’s input comes from the LFE channel of your receiver, use a “Y” splitter to divide the single input into two inputs for the Left and Right subwoofer inputs. This dual male-to-female “Y” splitter can be found at your local electronics store. If using line level connections from a preamp or signal processor, use both Left and Right inputs from your preprocessor or preamp and connect them to the Left and Right inputs on your subwoofer.
