STINGERSPW14TR Pro Series 4-Gauge Translucent Red Power Wire

For the price per foot of this wire made for car audio, you really can't beat it. Very Flexible, and not cheap! Definitely able to handle whatever amplifier you are hooking up to it! I personally bought it to wire into a distribution block so that I can hook up 2 different Amplifiers to 1 pair of 10" sub woofers and 1 pair of 12" sub woofers. It's going to be loud, and I don't think I could have found a cheaper, great quality wire.

It's good flexable cable. Remember, for it to be rated a certain Ga. it needs to be able to carry a certain load legally. So, it does look thinner, but if it fries - we know who will be at the receiving end of a lawsuit!

This is high-quality cable, and the gauge rating is most likely correct. I have samples of five different 4 gauge wires. The first sample I obtained from a local car audio installation shop. It was thick, but it seemed too light to be made of copper. So, I ordered small quantities of 4 other different brands found online, including a piece of very expensive SAE J1127 SGT type 2 low voltage automotive/marine cable. This latter cable has thicker strands and is much less flexible, but it was the only cable with detailed specifications, and I wanted a piece to compare with the other samples. I measured the overall weight and wire diameter of all cables, and I tested the insulation for heat resistance. I had planned to test the resistance of the wire, but my VOM's lowest setting is 20 ohms (accurate to about .05 ohm), and this proved insufficiently low to obtain meaningful results from testing 1-foot lengths of cable.The bottom line is that I found the Stinger Pro to be the best value of all samples. I like its weight, look, and feel. It works very well with marine-grade 4 gauge solder lugs, using liquid flux, solder pellets, and adequate heat. Its insulation held up well to the soldering heat, and it seems more mechanically durable than other similarly-priced cables.I see two reviews that question the accuracy of Stinger Pro gauge ratings. My measurements show that it has approximately the same wire diameter and overall weight as the very expensive SAE J1127 cable, and the Stinger Pro 4 gauge wire fits snugly in a 4 gauge marine-grade solder lug. It does not come close to fitting into an 8 gauge lug. Hence, I cannot understand suggestions by other reviewers that the Stinger Pro gauge rating is overstated.The only feature of the Stinger Pro cable that I question is the tinning. The fine strands are all nicely tinned, but I don't know whether this is an advantage. The tinning certainly must add to the weight and thickness of the wire (meaning less copper), and depending upon the alloy used in the tinning, resistance might be increased. For example, common solder alloys have only about 12 percent the conductivity of copper. Therefore, all other things being equal, I would prefer pure, untinned copper wire in my power cable.Clearly, at its price, the Stinger Pro is not the "best" wire you can buy, but it is better than many others, and I find it to be satisfying.You should always over-engineer electrical systems, and this especially important when using consumer-grade products. I am using the Stinger Pro cable to supply two 300 watt RMS (into 4 ohms) audio amplifiers in my SUV. The 4 gauge runs to a fused power distribution block, from which two 8 gauge Singer Pro wires run to the amplifiers, one powering four speakers in the doors, and the other powering a 10 inch subwoofer within the rear fender trim panel. Of course, even at moderately high sound levels, each amplifier is not likely to supply more than 25 watts to the speakers for any extended period of time, but to be safe, I used the full 300 watt rating for my calculations. Conservatively assuming that the amplifiers are 50 percent efficient, an output of 300 watts would require 600 watts of input power, or a maximum of 50 amps at 12 volts for each amplifier (a total of 100 amps maximum). According to the Handbook of Electronic Tables and Formulas for American Wire Gauge, 4 gage wire is adequate for transmission of 134 amps in chassis circuits, and the voltage drop for a 2-foot length (1 foot to the fuse block and 1 foot nominal for the return circuit) at 100 amps in a 12 volt circuit is only .1 volt. Similarly, 8 gauge wire is adequate for transmission of 74 amps, and the voltage drop for a 9-foot length (including the return ground wire) at 50 amps in a 12 volt circuit is only .6 volt.Remember that the transmission length must include the length of any ground wire running to the frame or body of the vehicle. The importance of adequate grounding cannot be overemphasized. Noise, such as alternator whine, in an otherwise properly functioning automotive audio system is almost always traceable to improper grounding. The distance from the body or frame grounding point to the battery is thought to add negligible resistance, provided the vehicle ground wires and straps are adequate. To be certain that my vehicle was adequately grounded, I ran additional 1 gauge "stiff" automotive cables from the battery to the frame, from the frame to the firewall, and from the frame to the body near my rear grounding point. The total length of these ground cables was less than 36 inches, and the voltage drop at 100 amps for a 1 foot length of 1 gauge wire is a negligible 0.025 volt.In sum, I do not hesitate to recommend the Stinger Pro power cable for automotive audio power supply applications.

seems to be 4 ga. but not really copper, maybe coper clad at best. didn't really look to close.It won't have the same ampacity as a copper conductor.

After reviewing many options for 4 gauge power wire I chose Stinger ProSeries 4 wire due to other excellent reviews. It is a terrific product and due to the many fine strands of wire, very flexible which I needed to run from battery to rear deck of our SUV. Also ordered a few feet of the same in black for the ground. In summary a pleasure to use and I recommend this product for any appropriate use of 4 AWG power wire. Service from the retailer was outstanding; I received my order in just a few days. Definitely a 5 star product and service.

I bought this for running two amps within my truck. It ran from my distribution block to the amp for my power wire. This wire is exceptional for its price. Very flexible and easy to run. The outer coating was easy enough to cut, but it was maybe too soft. Other than that it works just like it is supposed to. The wire is great and I would recommend to anyone.Can't beat the amazon price per foot of this wire!

i had some spools of this wire that was from years back, this is alittle less quality ,

This is the real deal. Actual 4 gauge of copper, not copper coated aluminum. The construction consists of hundreds of tiny strands resulting in a very compliant cable. The insulation is soft flexible rubber-like material that is easy to strip, perhaps a little too easy. Be very careful when pulling your run, it doesn't take much of an edge to cut the material.Given it's priced less than inferior products you can't do better.
