NVX MAN IOWA

The following review is for BAK02BL, which is a part of the bundle you are viewing.

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!!!

The following review is for BAK02BL, which is a part of the bundle you are viewing.

Not as thick as I though but it's good for my 1000 Watt amp. Have bought one for my truck 2 years ago and it seen like that one was big then this one but the same name and guage.

good wire

The following review is for BAK02BL, which is a part of the bundle you are viewing.

This wire is worth the money. I can't say what guage it is for sure, gut it's a full 1/2 inch or more thick and it is copper. The fuse and rca jacks are really nice also. The only thing wrong is the zip ties are so old they are brittle. Other than that, well worth it.
