Good, good and great

November 10, 2014

Got the 1metre length and the 5m length, Great quality of deliverance from head unit and crossovers, Very flexible and easy to use on tight angles

Just one thing, its so thin after few bents, felt like it could break easily, just a feeling of the softness of the wires, maybe it was just me but its great rca to go with.
