Review on NVX Copper Single Speaker XAPK8 by James Roper

One reviewer claimed the power cord was not copper. It is not true. Power, ground, and speaker wires are silver-tinned, oxygen-free copper. Silver plated copper wire, which conducts electricity with less resistance than ordinary copper wire and also has better resistance to corrosion. But it looks like aluminum wire. So I think I can understand the confusion. The weight should dispel any doubts. I am very satisfied with this kit. Loved the engine cover. A regular shell tears too easily in my opinion (hence the docked star). but I can absolutely recommend the product.
