Perfect

Solid built and well made. Worth the money and I expect will last a long time. Sonic Electronix is outstanding!

Best you can buy!

I bought this amp kit to power my Eclipse XA1200 amp which powers my Eclipse SW9102 titanium sub. I have no power issues at all using this cable. This stuff is thick and durable so don't go cheap and buy something else! Highly recommended to anybody!

good kit

Installed this kit into my 03 GMC sierra 2500HD with no issues. It worked very well with the Rockford T600-2 amp that I was running.

Great

This is the best wiring kit I have ever owned. I have had many wiring kits before and this is for sure the best. Real flexible.

Amazing

This Power and Ground kit is by far the best 4 AWG kit on the market, the wire is extremely flexible and is standardized, meaning it IS actually 4 AWG. It comes with butt crimp connectors to attach the remote wire and zip ties, All a great fuse holder. Highest quality I have ever seen. Make sure you buy replacement "MAXI" fuses, however.

Worth The Money

When you consider that this wiring kit extends your Rockford Warranty, it's a no brainier.

You have to have an install kit for your amp, and you want the good stuff, right? Get one!

Solid Wire!

This amp kit is great! A little bit more expensive than some kits but it will deliver solid, clean power to your system. The wire is without a doubt true to gauge and the accessories (rings, fuse, etc.) are of great quality!

yup go rockford!

I bought this obviously to power my system, gauge seemed true as is all of Rockford's proclamations, i wish i would have gotten one that was 3 ft longer though. This would be great for a truck or a mid sized car, if your putting it in a Cadillac though get the 20 ft cable.
