I bought this kit for a customer who has 2- Hifonics Amps, a BRX2000.1 & a BRX640.4, the wires were flexible & a ease to run in a 04' Monte Carlo! I was alittle concerned cause of the price but let me tell you, this price is a SUPER STEAL! We are running about 2328watts of actual power & wire is holding up great... Definitely will buy again when I need a big power wire kit! For Sure... I'm a huge NVX fan wires & all, this is great too!! NVX MAN is out!!!
