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.

Plenty of cable

An excellent install kit with easy to work with cable. Very flexible due to it's multiple high strand count and tough but supple insulation.. I had to make some very tight turns and this cable worked great for that. Rockford makes sure you have plenty of extra cable and all the connectors needed for a custom wire length. A added plus is that it extends your FACTORY warranty when used in conjunction with a Rockford amp.(check specifics)

Rockford 4 G wire

This is a great kit. I feel a person could buy this and never have any
problems. Buy this knowing you are going to get a high quality kit.
Just make sure it is the size wire you need.

Monster Cable

Ok so I didnt realize my Pioneer gm6400 power wire was undersized. requires 4awg and I had 10awg. My amp was cutting off at high decibels and kinda hot with my recently upgraded 6x9 momos thought I needed a bigger amp until I noticed the wire..
I installed this Kit and what a difference, I am getting 14v to the amp and now I can crank up the volume with no problems and the amp is barely warm.
Great product recommend for anyone with an amp and adtermarket speakers. Thanks Sonic

Wiring kit that changed it all

Great flexible wires, true 4 gauge. I couldn't be happier with this wiring kit. I hooked it up to a Rockford T1000-1bcCP and it made a clear difference. I will stick to Rockford in my future audio set-ups and Sonic is going to be my choice of store.

Nice cables.

I don't use anything other than Rockford cables for any setup, the cables are nice and heavy, but very flexible which is good when your running cables at turns and angles, but still has a strong and durable jacket that withstands pulling through narrow openings, also, they are filled up to the stated gauge, not like grey market knock-offs that I have tried and thrown away, lost time and money on. They are expensive but worth the $$$.

Perfect Kit!

Kit comes with all the connections I needed to install the kit in my car (wires, connectors, etc.) the only problem I came into was because the wire is a TRUE OVERSIZED 4AWG, my 4awg terminals on my amp just barely fit the wires. But at least the advertising is true and definitely delivers some good power.

TRUE 4 GAUGE...

The rockford system is always the TRUE guage vs other brands out there that have thick insulation and hardly no copper in fact some companies will pass 8 guage off as a 4 guage in their book and increase the insulation. Know when you buy rockford fosgate wiring you are truely paying for the copper.

Oversized

Not under, but oversized. Had to shave a few strands just to fit the holes in a rofo punch 1000 bd. Really flexible, heavy wires. Reeks of legitimacy.
