As you're building your car's sound system, don't forget the speaker wire. No matter how good your speakers or amps are, your investment is worthless if your speaker wire can't handle the high power that lets your speakers strut!

Rockford Fosgate's triple-wire Gamma Geometry™ design makes Riot Series speaker wire outperform normal speaker wire by using three cores (positive, negative, and an "inductive control core" of pure dielectric) in a tight, weave design. Unlike conventional twisted-pair design, the conductors repeatedly cross each other at the optimum 90 degrees, resulting in significant noise canceling. Since the wires are not twisted, there is no coil effect, and no additional resistance.

If you want smooth highs, focused midrange, and tight bass, Riot speaker wire is IT! You'll enjoy higher output, stronger bass and better imaging from your music when you switch to Riot speaker wire. CPRG13 13-gauge speaker wire is priced per foot — enter the number of feet desired in the "quantity" field of your shopping cart. 1-year warranty.

Product Research


Gamma Geometry Technology: Gamma Geometry is a new development in cable technology. Positive and negative conductors are woven together with a "Inductance Control Core" of pure dielectric (insulator). Positive and negative conductors cross at an optimum angle of 90 degrees, reducing the proximity effect. Conductors remain physically close maintaining excellent noise rejection. By reducing proximity effect and maintaining noise rejection in a single design, Gamma Geometry achieves significantly better signal accuracy and faster, quieter signal transfer.
