If you are connecting speaker lines directly to the amplifier, then you are running high level. As the cone moves the air inside of a specially designed enclosure (speaker box) deep bass, contained in the musical input signal, is produced. The subwoofer cable connects to the Subwoofer 1 Pre-out connection and to the subwoofer's Line-In right input. If you have a processor with very low output so you can use a Y-splitter. The speaker terminal outputs are the high level ones. It still sounds kinda low, specially when listening to music. High level and low level are referring to the source voltage. I believe there are three different inputs on the back of most subwoofers, red & white rca looking ones, the spring(?) connectors that are look like regular speaker ones, and finally the LFE. 5.0 out of 5 stars 1.
