DB LinkCK4Z 4 Gauge Competition Series Amplifier Installation Kit-Blue

Nice amp kit for the price. The 4-gauge power ground cables are actually 4-gauge - not 6 or 8-gauge covered in a super thick insulator pretending to be 4-gauge! The RCA cables are decent and have nice flexible housings to route and snake through to your interior easily. A covered ANL fuse holder (with 100-amp ANL fuse included), matching ring terminals, remote wire, and split loom are also included for a complete install.Speaking of the fuse holder - I don't understand the reviews where people complain about the fuse holder not being waterproof; if you wanted a waterproof fuse holder, then buy a kit THAT SAYS it has a waterproof fuse holder! Don't buy this (knowing it's not waterproof as easily shown in the product photo) and then complain about it.However, What keeps me from giving this kit 5 stars is one detail that other reviewers mentioned: I don't like how DB Link precuts about a foot of the 4-gauge for the battery connection. It would have been better if they left the cutting to the customer, as I had to change the installation plan slightly to work with the precut cable. Other than that, this is a solid installation kit gives you real 4-gauge for the money.

I bought this kit for my first time installing my own car system. I've learned much and can safely conclude that this kit is relatively inferior and low quality, but it's perfect for beginners installing a subwoofer amplifier.The only major gripe I have about the kit is that the RCA cable that came with the kit is utter crap and had to be replaced. It picked up noise from an unknown source. This wire was run along side a Rockford Fosgate RCA cable. The RF cable did not have any noise whatsoever and upon replacing the DB Link (DB Research) cable, the noise disappeared.The fuse holder and fuse/fuse type really do suck, but again, it works. The fuse holder functions, but there is room for improvement, such as making it water proof and not simply a fuse tent. The fuse they include with the kit (if I recall correctly) is either a 100 amp or 150 amp ANL fuse. Which is fine for high powered applications such as monoblock subwoofer amplifiers, but if you're going to run a multi-channel amplifier like me, it's best to get a lower amp fuse/fuse holder and swap it in. A rule of thumb I learned was that AGU fuses were for low to medium power while ANL were for high power.As for the crimping, yes, the alloys used are a bit harder than the norm, but nothing I couldn't hand crimp myself with a proper crimping tool (that you can get for ~$40 average from any brick and motor hardware store probably even less online). Oops, I made it seem like it was easy. No, it was a bit strenous for me, but I didn't have to hammer anything.The speaker wires seem okay, and are roughly 18 AWG (compared to the 16 AWG I bought at Wal-mart anyways). 18 AWG is plenty for regular speakers and the bigger sizes like 14 and 12 should only be used for high power subwoofers.

Wire was a good quality, appeared to be true 4 gauge wire. Length of power wire was adequate to run from the battery to the trunk of my 2014 Mustang, but not much extra with which to work. Note that on my car, the battery sits at the back of the engine compartment on the passenger side, and I made a run nearly direct from battery to trunk staying on the same side of my car - so the length may not be adequate for longer vehicles. The power cable came pre-cut at about one foot for the fuse, but only had one connector attached so get ready to crimp or solder. Fuse itself appears to be of good quality, but fuse holder is a bit tacky, excessively large, and not the easiest to mount. It also required reinforcement to close as securely enough for me to be comfortable. The fuse holder is the main reason I took off one star. Otherwise, it works great and if you don't need to make a really long run it will do the job. Competitively priced.

If you're looking at buying this product, you're definitely on a budget. It's a good price for the wires that are included (copper is still expensive for some reason).The fuse holder is really not even splash-resistant - it should only be mounted horizontally.The terminals on this are made of the harder alloy that's fairly standard in these type of kits; it's not easily crimped like normal copper is.If you are shopping in this price range, you probably won't have the appropriate tools to crimp the larger terminals. Professional install tools are really expensive. I have a heavy duty crimper and, still, I had to take a hammer to first the terminal clasps, then to the crimper handle (yes, inelegant, I know).If this were to be your only purchase on an AMP install, it does include almost everything you need, but with the stereo wire, I'd assume it's only meant for a 1 or 2 channel amp . . . speaker wire is cheap though.

It should be said that I'm not comparing this to some $100+ Monster cable kit or something of that caliber, but for what it is, it does the job great. I'm currently powering a dual 10" setup in my F-150, subs are rated 300W RMS each, and it seems to work perfectly. I've never had an issue in 6 months now, and I've had it up nearly to the max. I used to have my Pioneer amp hooked up via a KnuKoncepts 4GA kit in my last vehicle, and the wire was so effing thick, I couldn't fit it into the terminals of the amp, but this wire fits great.
