Q: How does this hook up when there is a left and right on the sub?
A: Plug into the left jack or LEFE jack.
Q: Do you have to use the ground? My marantz has no place for it and neither does the CV subwoofer.
A: Although I found no reference for it I did use the ground wire and just connected each end to any available screw that went into the metal frame. Couldn't hurt anything and I felt better for making the extra ground connection.
Q: What is the wire gauge of this cable?
A: Good question, but not one that anyone outside the company can answer without cutting into one. AT $99 a pop, it's not likely anyone would do this unless the cable goes bad. The cables have a sheath hiding the true diameter and construct. In the AudioQuest family of cables, this one's in the middle of the lineup at about $100 for a 10-ft cable. The Boxer cable will cost about $200 and the Husky about $500 for the same length. How much is the extra quality sound worth? As much as you want to pay.

Enjoy cleaner, clearer, more naturally beautiful sound from a wide range of modern and legacy digital devices—CD players, cable boxes, HDTVs, powered speakers and subwoofers, soundbars, laptops, portable-audio players, game consoles, and more—with this high-performance, low-noise AudioQuest Carbon optical cable. Like all AudioQuest products, Carbon Optical cable is meticulously designed for outstanding performance and exceptional value. The single large fiber in most Toslink cables allows light from the LED source to enter at many different angles, causing signal paths of various lengths, smearing the data across time, reducing bandwidth, and causing a loss of information: audible signal distortion caused by the complex dispersion of light. AudioQuest’s Carbon Optical cable, however, features 19 narrow-aperture fibers of the highest-purity synthetic, creating a cleaner, more direct signal path with significantly reduced dispersion and lower distortion. Further, AudioQuest Carbon Optical cable uses precision-polished fiber ends. The non-metallic connection provides critical galvanic isolation, eliminating the transmission and pickup of induced radio-frequency noise. Includes 3.5mm mini-toslink adaptor. All standard lengths of AudioQuest Carbon Optical cable of 8m and greater feature a PVC outer jacket rated for in-wall use. Enjoy cleaner, clearer, more naturally beautiful and intelligible sound with AudioQuest Carbon Optical cable.

This AudioQuest Boxer BOXER03 subwoofer cable ensures efficient transmission, utilizing silver-plated copper conductors and a noise-dissipation system to reduce signal distortion. PE air-tube insulation preserves dynamic contrast for quality sound.
