How do i connect my velodyne sub to my onkyo 805?

Ok so i noticed that in the back of the subwoofer it has the red and white entrys so do i just connect the red or how do i do it?

[DerrellB]

A y splitter should do the trick.

oh ok does it make any difference in the sound?

3-6db gain in volume. The way I look at it, let that gain you some volume instead of using more amp than you have too!

+1. This is useful if you want to trigger the auto power-on of the subwoofer easily when you're playing movie/music at a moderate level of volume (though manipulate the subwoofer channel output level within the receiver's speaker settings can also do the trick).

If you don't have a Y splitter don't run out and buy one, just plug your sub woofer cable into either the L or R jack as indicated in your subs manual.

People claim that a splitter will give you a 3-6 db boost but in all honesty it's a placebo effect. You can achieve the same effect by simply increasing the subs gain in your receivers menu.

Edit> the main purpose for the L and R jacks on a sub is for 2 channel stereo amps.

If you look at the jacks one of them might be labeled LFE. I have a Velodyne and my left jack is labeled LFE.

As far as as the Y-spltter, I'm in the placebo camp. It does boost the output but does drive the internal amp harder. This can be achieved by just simply turning up the gain on the sub or receiver. Here's why, consider the amp a series of mosfet transistors, lets say your receiver is outputting 3 volts to the sub, that 3 volts is sent to the gate on the mosfet which in turn opens up the channel between the source and drain, thus your output. Increase that gate voltage with a y-splitter and that channel between the source and drain opens even larger, allowing more electrons to flow, thus making the sub sound louder. This can be achieved by turning up the gain by the same amount.

Granted this was a real simple explaination of how an amp works but you should get the jist.
