Is this PE Jacket + PET + HDPE Insulation so it does not corrode like the pictures? This wire I got from WireZone, very cheap! I am needing wire for 6 speakers, 250', that is near a salt pool. Suggestions?
1 Answer
Hi Phil:

I am still waiting to hear from our Factory regarding the specs of our CL3 speaker wire. Our wire not only features a CL3 rated outer jacket where it is certified to install in a wall for all residential applications and most commercial installs. The exception for industrial applications the cable can not mount in a heating/cooling duct (that would-be a cable with an outer plenum jacket). The CL3 will not burn only melt and not give off toxic fumes if a fire does break out. An uncertified cable would spread a flame-like a fuse between the stud bays. We also add a UV coating in the outer jacket, allowing it to use as a direct burial cable. I have never seen a cable look like your image and especially our cable. I will post the specs on our page when I receive them. I will send you an email as well. By the way, a rule of thumb when selecting as speaker cable with full range signal: 1 to 80 feet; 16 AWG, 81 to 200 feet; 14 AWG and 200 plus; 12 AWG. When running, just a Low-Frequency signal like for a subwoofer; 0 to5 0 feet; 14AWG, 50 plus; 12 AWG. Note if you are using a Volume Control or Speaker Selector most of their input and output connectors are made to accept 16 AWG. 14 AWG will work but is tight. Most amplifiers/Receivers and speaker connections will allow up to 12 AWG.

If sealed with proper heat shrink connectors, can this cable be used to install marine speakers?
1 Answer
Hi Manuel:

Our cable is multi-strand and Oxegen Free Copper. Two keys specs for Marine application. True Marine cable adds a coating of tin to each conductor and the jacket is oil and heat resistant. You might want to tin the exposed ends of the cables. There is a reference to SAE (Society of Automotive Engineering) rated cables. These would be for connecting Speakers only. The outer jacket is CL3 rated (fire retardant, approved for in-wall application for all residential and most commercial). It does not burn or give off toxic fumes. We add a UV protection so it can be used for direct burial. I hope that helps.

i'm looking to run speaker wire from an inside receiver, to 4 outdoor speakers. Can i use this wire w/o running conduit under my deck or would rodents/weather be a concern?
1 Answer
HI Josh: You can run this wire above ground; I might try and attach the wire to the bottom of your deck, so it is in the air rather than just laying it on the ground. It has UV protection in the jacket as well as being fire retardant (CL3). TL/5159

what gauge is best for outdoor speakers that the wire will be in the sunlight and on west facing wall
1 Answer
Hi Ron: All three gauges of our CL3/FT4 direct burial custom install cables feature a UV additive to the outer jacket so there is no problem being exposed to sunlight. And depending where you live in Oregon sunlight might not be a problem anyway. I know, I live in Lake Oswego myself. The rule of thumb when considering which gauge wire to use on runs up to 80 feet ; 16 gauge, 80 to 200 feet; 14 gauge and 200 feet and longer 12 gauge. Also if you are using a speaker selector or indoor volume control they typically work best with 16 gauge input/output. If you are running low frequency for a sub than 14 gauge up to 50 feet and 12 gauge beyond that. TL/4394

Will the wires corrode? I used a different brand of wire that claimed to be weatherproof, but it corrodes every season, and I have to cut it back about 3' to fine uncorroded wire.
1 Answer
Hi Devon: Are you terminating the wire with standard wire nuts or with something like our aqua blue wire nuts with silicon filler? I have not had any complaints regarding corrosion. And all tech emails and upload your plans come through me. TL/4132

You stock Monoprice 104045 100 ft 18AWG CL2 Rated 2-Conductor Oxygen Free Pure Bare Copper Speaker Wire Cable, I wanted to ask if this was suitable for outdoor use and UV safe, also what is the main difference with 12/14/18AWG thickness?
1 Answer
Hi Mike: We do not stock Monoprice cables. They are another Brand not associated with our OSD brand. But all of our OSD Branded speaker cable are CL3/FT4 rated certified for all residential in-wall/in-ceiling installations and most commercial applications except running the wire in heating and cooling ducts (that would require Plenum rated). All of our jackets are thicker and are UV treated so they can be used as direct burial. Regarding the gauges of the speaker wire a general rule is 0 to 80 feet use 16 gauge, for 80 to 150 ft use 14 gauge wire and 150 feet and beyond 12 gauge. Good luck TL/3769

What is the difference between a 14 gauge and 16 gauge wire. i would like too know what wire is best for outdoor speakers
1 Answer
Hi Dave, The larger the gauge of the speaker cable, the longer the run can be. However, gauge ratings can be confusing. Smaller gauge numbers equate to larger sizes; therefore, for up to 80 feet, you can use 16-gauge cable. For runs longer than that, consider the 14 gauge to ensure that volume capability and sound quality are not degraded. CL/MA 1820

What is the difference between a 14 gauge and 12 gauge
1 Answer
Hi Kathy, Longer wire runs require thicker the cable, and the 12-gauge speaker cable is the thicker of the two. If your longest run is over 100ft, go with the 12-gauge speaker cable. CL/MA 1528
