Monster has been making wire for a long time; I've been using it on and off since 1993. They were more boutique then; more mainstream now, but this has helped them to offer a wider array of products at lower prices. Monster products can be found almost everywhere, and this typically hurts image and sales to enthusiasts like me. The good news is that Monster is big enough so they can make price point products for the masses while still offering cutting edge products for the enthusiast.
This speaker wire is by no means cutting edge, but it does have useful trickle down features that make it a high value solution. Much better than "zip" wire (twin conductor like lamp wire- the original speaker wire), the positive and negative leads are individually insulated, helix twisted, then encased in a clear PVC jacket. This results in an overall cable diameter of about 1/4-inch. The PVC outer jacket is smooth, making it easy to route and pull through the vehicle; I performed a full custom rewire of a medium sized SUV and had no difficulty in this area. The only downside to the outer jacket (and the reason I gave four stars) is that it has to be slit and trimmed back to expose the two inner conductors. This is a minor inconvenience compared to all the benefits the outer jacket provides (ease of install and additional protection), but you do have to be careful not to cut through the insulation of the inner wire or your finger (I slipped once and got my thumb pretty good- I found a good pair of cut-resistant gloves for day two of my install and will never work again without them!). As it turns out, I never did cut the inner jackets by mistake; I would say it is just as easy to make a bad cut on cheaper zip line. The outer PVC jacket is very tough but pliable; this renders the whole cable flexible enough to work with, but stiff enough to stay where you want it.
This is true 16-gauge wire and accepts blue (16-18 gauge) crimp-on connectors perfectly. Overall, a good quality, basic speaker cable- especially for the price. Recommended with a warning to be careful cutting the outer jacket, then highly recommended.
