energeaster 14 Gauge Wire 100FT, 2 Conductors Electrical Wire Red Black Cable, Low Voltage 14 AWG Copper Clad Aluminum Extension Cord for Speaker Wire, LED, Automotive 12V/24V DC

What it is and why I picked it up

I put the Energeaster 14‑gauge red/black cable through a few real‑world jobs—landscape LEDs, a small 12V fuse block in a vehicle, and a pair of bookshelf speakers—to see how a budget, copper‑clad aluminum (CCA) low‑voltage cable holds up. On paper, it’s a straightforward value play: 100 feet of bonded red/black conductors in a flexible PVC jacket, rated −35°C to 105°C, meant for 12V/24V DC systems like LED strips, automotive accessories, and general low‑voltage hookups.

CCA is lighter and cheaper than full copper, and that’s the tradeoff most shoppers are evaluating. My aim was to find out where this cable shines, where it compromises, and how to spec it correctly so you don’t run into voltage drop or durability issues.

Build quality and handling

Out of the box, the cable coil was tidy and didn’t spring into a tangled mess. The jacket feels a notch thicker than many bargain “zip cord” options, which pays off when pulling past sharp edges or through corrugated loom. It’s supple in the hand, easy to route, and it doesn’t kink easily. The bonded conductors separate cleanly by hand; I could peel them apart without fighting the webbing, and they stay together well enough during pulls.

Stripping was uneventful with standard 14 AWG notches—no gummy residue, no jacket tearing. The conductor is clearly CCA: aluminum core with a copper skin. That copper cladding helps with surface oxidation resistance and solderability, though for repeated flex points or environments with vibration (e.g., under‑dash harnesses) I had better results crimping insulated spades or using ferrules instead of tinning the ends.

The jacket is marketed as flame‑retardant, moisture‑resistant, and resistant to acids and alkalis. I can’t lab‑verify all of that, but practically, it feels durable, and it shrugged off a week of damp mulch in the garden without taking on water. There’s no UL/ETL marking on the sample I used, and there’s no direct‑burial rating claimed, so treat it appropriately: low‑voltage, out of the wall cavities unless your local code allows, and in conduit or protected if you’re going outdoors long‑term.

Electrical performance and what to expect from CCA

Here’s the key point with CCA: it has higher resistance than pure copper. For 14 AWG, expect roughly 1.5–1.7× the resistance of copper. In practice, the run length and current matter more than the label. I measured a resistance in line with typical 14 AWG CCA, and that informed how I used it:

• Short, modest‑current runs (LED strips, small amps, sensors): no issues.
• Long or high‑current 12V runs: plan for voltage drop or choose heavier gauge/pure copper.

A quick example for 12V lighting: a 5A load over 50 feet one‑way (100 feet round trip) on 14 AWG CCA can drop around 2V. Many LED strips will visibly dim with that much drop. If you must go that distance, break the load into shorter home‑run segments, step up to 24V where possible, or jump to 12 AWG copper.

For audio, resistance matters but the context is kinder. On an 8‑ohm speaker at living‑room distances (say, 25 feet one‑way), the additional resistance of 14 AWG CCA is still small relative to the load and didn’t audibly change the system’s response in my testing. I wouldn’t use it for long runs to low‑impedance (4‑ohm) towers, but for modest setups it’s fine.

In use: LEDs, speakers, and a 12V fuse block

• Landscape LEDs (24V): I ran multiple 8–12W spotlights over 20–30 foot segments. At 24V, the system tolerated the modest resistance well, brightness was consistent, and the jacket handled being pulled through conduit and clips without scuffing. The red/black pairing made polarity checks quick.

• Small speaker run: For a secondary room, I used a 20‑foot one‑way run to 8‑ohm bookshelves. The cable stayed flexible enough to route behind trim, and banana plugs crimped firmly onto the conductors. No noise issues, and no perceptible loss versus 14 AWG copper at that length in casual listening.

• Automotive 12V accessories: I added a fused distribution block and a low‑draw relay. The cable’s flexibility was great for making tidy looms, and it accepted standard crimp terminals well. Under‑hood wiring demands some caution: keep it away from high‑heat zones (headers, turbos) and protect with split loom. The 105°C rating is decent, but localized engine bay hotspots can exceed that. As always, fuse close to the source and size for the conductor.

Durability notes

• Jacket toughness: Better than typical budget CCA cords I’ve used. It resisted nicks when pulled through plastic grommets and stapled channels. I’d still avoid metal staples; use plastic cable clips or insulated staples sized correctly.

• Moisture and UV: The jacket didn’t absorb water in short‑term outdoor use. For permanent outdoor installs, I would use conduit or UV‑rated raceway, since there’s no explicit UV/direct‑burial rating.

• Corrosion: The copper cladding helps, but in marine or salt‑spray environments I’d step up to tinned copper marine‑grade wire. For general indoor/outdoor low‑voltage use, the CCA held up fine across a few weeks of exposure testing.

Practical sizing advice

To decide if this cable fits your job:

• Keep 12V runs short when pulling more than ~3–4A. If you need 8–10A over distance, consider thicker wire or moving to 24V where the same wattage draws half the current.

• For LED strips, home‑run multiple feeds back to the power supply rather than daisy‑chaining long distances.

• For speakers, 14 AWG CCA is acceptable up to ~25 feet for 8‑ohm loads; for longer runs or 4‑ohm speakers, 12 AWG copper is safer.

• Always fuse to protect the conductor (not the load). For 14 AWG CCA, I keep branch fusing conservative.

What I liked

• Flexible, thicker‑feeling jacket that resists kinks and handles pulls well.
• Bonded red/black conductors keep wiring organized and polarity obvious.
• Easy to strip and terminate; works well with crimp connectors and ferrules.
• Sensible temperature range for low‑voltage and light automotive work.
• Good value for general‑purpose 12V/24V DC projects, especially at 100 feet.

What could be better

• It’s CCA, so resistance is higher than copper; long/high‑current runs need planning or a heavier gauge.
• No listed direct‑burial/UV rating; protect outdoors with conduit or raceway.
• Not a substitute for in‑wall building wire or mains AC; it’s purely low‑voltage hookup cable.

Who it’s for

• DIYers building LED lighting, small electronics, and 12V accessories who want a flexible, tidy two‑conductor cable at a budget price.
• Hobby audio users wiring short‑to‑medium speaker runs without chasing audiophile marginal gains.
• Vehicle upfitters adding low‑draw circuits, relays, or accessories with attention to routing and heat protection.

If you regularly push 10–20A over distance, or you do marine/outdoor permanent installs, I’d steer you to full copper, heavier gauge, and UV/marine‑rated jackets.

Tips for best results

• Use ferrules in screw terminals to prevent strand splay, or choose quality crimp connectors sized for 14 AWG.
• Keep polarity consistent—bonded red/black helps, but label both ends on long runs.
• For LEDs, prefer 24V strips and distribute power feeds to minimize voltage drop.
• Bundle with loom or braided sleeve where there’s movement or abrasion, and avoid tight bends near terminations.

Verdict

The Energeaster 14‑gauge red/black cable is a solid, budget‑friendly low‑voltage workhorse. The jacket quality and handling are better than I expected at the price, and for the typical 12V/24V tasks—LED lighting, light automotive accessories, small speaker runs—it performs reliably as long as you plan for the higher resistance of CCA.

Recommendation: I recommend it for general low‑voltage projects where runs are modest and currents are reasonable. You’ll appreciate the flexible jacket, easy termination, and tidy bonded conductors. If your use case involves long distances at higher currents, permanent outdoor exposure, or environments that demand strict ratings (marine, in‑wall, or high‑heat under‑hood), step up to heavier‑gauge, full‑copper cable with the appropriate certifications.
