I ordered this kit about six months ago, and in my book this the real deal when it comes to quality. I installed it in my vehicle and its currently wired to a 900 watts rms amp.(kit rated @ 1000 watts)
No issues have surfaced. The thickness is 4 gauge as advertised, not like others that make lame claims on their labels. So buyer beware of fakes when ordering your amp installation kits. I am very satisfied with this purchase! You know what they say "You get what you pay for!" It might be a little pricey but its worth the money. Kicker has good products and stands behind their name. I strongly recommended it to anyone who knows how to properly install sound systems.
