Best cable you can get.

I bought this cable knowing it was a great cable. I've been told it doesn't get better than this. I have it connect to my 1500 Rockford Fosgate amp and 2 12" L7 square kickers. It sounds great and hear nothing but bass coming from my speakers. Must buy!

Great Kit

Great kit, I have a kenwood 1800 watt amp that I am using. The one thing that I really liked about this kit is that the power wire is actually long enough to reach my trunk space and I have plenty of slack left over.

Rockford delivers again!

I have always been a big fan of rockford and usually like to stick to just a few brands. Had this amp kit on my last civic hooked up to a rockford P1000-1D amp and this kit delivered the power! This is a true 4-gauge amp kit unlike some of the other kits on the market. Will never buy a different brand amp kit again!

awesome wiring kit

this kit was perfect for my setup. the included 100 amp fuse was just the right size for my amp. also the extra strands of wire compared to regular cable made it able for me to not need a capacitor in my system. The fuse block could be a little farther from the end lug, and the lugs would be a lot better if they were soldered on ins ted of crimped but its perfect for the price.

Good overall

This was a pretty good buy but it wasn't perfect. It didn't come with any crimps for my ground wire to connect to my amp. Luckily I had a lower level kit that I didn't want to use with my system laying around. I saw another review about the fuse holder. Same here. Wasn't something I had seen before and took me a little while to figure it out. I used this to connect my 2 Kenwoods in my 97 civic myself 6 months ago. All the cords were a good length except maybe the power cord. It fit but I didn't have really any slack. The wire was definitely true gauge wire. Haven't had any problems since I've hooked it up. Little pricey for the inconveniences but it does the job well.

Hard to find in stores.

The products from Sonic are top notch. They had everything I needed that I couldn't find in the store. They arrived quick and well packaged.

Good kit-

It was a good kit, I did have a couple problems figuring out the fuse block (it was nothing that I had seen before) but I figured it out. Other than that- it was a good kit at a great price.

meets your needs

This wiring kit has almost everything you need only thing I would suggest is buy some more 16g speaker wire.

Great buy!

Bought this kit to wire up my 10DCVR122 loaded enclosure & a Kicker CX.600.1. Kit comes with everything needed to wire up your system. All wires provided are more than enough which is good for someone like me who moves it around every once in a while. I'm 100% satisfied with this purchase & I would recommend it to anyone. I personally would buy again!

Pros
Comes with everything needed
Delivers the power your system needs
Great quality

Cons
Didn't come with stickers(lame)

How Can It Get Any Better?

If your looking for a 4 gauge kit, especially for the money. Look no further, you can spend $50 more on a 4 gauge kit & the quality just won't get any better. The most flexible cables I've ever used, & very true to the 4 gauge spec. As soon as you open the box & take your cables out, you immediately know that you purchased the highest quality wire that money can buy. The kit came with everything needed for the install, no problems with the fuse holder, no problems whatsoever. I've had this kit 8 months & running, I recommended this kit to a friend (which is super picky about his wiring ect) & he wouldn't ever buy a different brand of wiring now. I highly recommend this wiring kit, I imagine a man could keep this wiring kit well over 10 years & never have a problem out of it.. If I get another vehicle, I'm taking it out and transferring it over.. Well worth it, don't spend money on a cheap kit & have to wind up buying this kit & being out of more money. Trust me, it's the best, absolutely no regrets here, 110% satisfaction.

Great kit

This kit powers my setup with no problems. True 4gauage wiring. Fuse was a bit tricky but managed to get it on there.

Great Quality!

Great wiring kit. Only thing that I had trouble with was the fuse holder. It took a few minutes to figure out!
