Size: 1/0 Gauge | Dual Amp Kit
I worked in the Car audio industry for a long time. I wish there were quality kits that didn't break the bank like this around when I was in the business. This is hands down the best 1/0 amp kit I have every used for the money. Out of all my time working in the car audio industry. The only place Ive seem people skimp on the most is the wiring and most of these shops arent going to tell you that those cheap cables and wires they are installing are to thin to feed your amps with an adequate amount of power and can even be a hazard. Anything over 1000 watts and over 12' of run. You should be using 1/0 gauge or larger. Anyway I myself did not want to spend an arm and a leg on an amp kit like Scosche, kicker, or fosgate amp kits so I did some research to see what I could find. People rave about these kits and the consensus is right. These kits offer quality wiring at a minimal hit to your wallet. What I was amazed at is the level of care that went into putting these kits together. The main blue power line is wrapped in wire loom for about 5 feet and you cut it where you need to install the fuse holder. They provide you with extra shrink wrap so that when you cut the wire you can shrink wrap the edges of the cable and loom so the loom doesn't come unraveled. The fuse holder is great quality. Its better than fuse holders on many of the more expensive kits Ive seen. The distribution blocks are not lacking in quality either. The cable really is true spec wiring. Its not all insulation like a lot of cheaper wires passing themselves off as a particular gauge. This kit gives you plenty of wire to install amps in the average car or truck. Though if you are doing a van or an SUV and installing your amps all the way to the rear of the vehicle. This kit may not be long enough. So year stop second guessing whether this kit is the quality that you are looking for, because it is. Just order it and be amazed when you first open it up and take a look.

Size: 4 Gauge | 6-Channel
I got this wiring kit for a full system upgrade to my 2016 Subaru Crosstrek. Because I was adding an Amp, Sub and replacing all 4 main speakers, I wanted a kit that had Power, Ground, speaker wire, and a full set of RCAs. This was the only kit I could find that came with a 6 channel RCA for a reasonable price. The great thing about this kit is that it comes with everything you need if you’re installing a 5 channel amp. The wire is all true gauge spec and I didn’t have to purchase any additional wiring or accessories to install. This kit made a HUGE difference because there was enough wiring for all the parts of the system and the quality of the wires is very good, so for the price, it added tremendous value to the system. I easily could’ve spent three times as much for the same wires if I had bought them all individually.

Size: 8 Gauge | Power Kit
This is OFC wire. Don't let the silver plating on the copper fool you. I was trying to tin the wires for installation since I didn't have any ferrules and the wire was not warming up with my soldering iron. I figured it just isn't powerful enough for 8 gauge wire. So I pulled out my torch which did work, but it actually melted off some of the tinning and you can see the exposed copper strands underneath. The fuse block is a quality piece and well built. The length of the wires was sufficient to wire an amp behind the back seat of an F150 supercrew. That's a pretty long run. The speaker wire was nice quality stuff too. They give you all the connectors you will need to wire a single amp. One strange issue that I did run into was that the nice braided end of the cable had a ring connector on it which was nice, but you can't use that on the fuse block. I had to cut that off about a foot from the end, strip both ends of the cable to insert into the fuse block and then connect the ring terminal to the battery. I think it would be a lot nicer if they included a short braided piece with the ring connector and the long cable with the braiding with a just straight end with a ferrule on it. The braided section was long enough to make it all the way past the firewall and into the cab. Very nice. I would buy this kit again if needed. I don't think you will find a better quality kit for the price. If you do this often and buy bulk cable and connectors obviously you don't need this, but for a one time installation for a DIYer, it was perfect.

Size: 1/0 Gauge | Dual Amp Kit
The quality of this wire kit is immediately apparent once you lift the box and open it. It's very very high quality heavy duty 99.9% OFC silver coated wiring with extremely soft flexible insulation. Don't be fooled by all the cheap CCA cables/kits out there for 1/4 the price cuz you'll end up regretting cutting that corner. Actually the 1st 6 feet of the main power wire comes with an extra layer of "tech flex" protective looming pre installed for added safety and stability in the engine compartment and all the potential sharp edges between the engine and cabin. The fuse block easily accepts 0 or 4 ga. wire (with metal inserts) and comes with 3 different ANL fuses rated between 100-300 (approx) and the added ability to accept mini ANL fuses if need be. Both of The distribution blocks are small in size but big in quality and wiring flexibility with 1x 0 or 4 ga input (with metal insert) and 4x 4 or 8 ga output (with metal insert). Just add the RCA and speaker wiring of your choice and done. Or this makes a great foundation to start wiring a system especially if you have intentions of adding or upgrading to more powerful gear in the future.
