Description:
This 12 gauge 4 conductor speaker cable from Monoprice delivers a ready-to-install option for in-wall audio runs where cleaner wiring and reliable signal transfer matter. The jacketed white PVC finish keeps the cable discreet behind baseboards or inside walls, and the CL2 fire safety rating makes it suitable for residential in-wall installations according to the manufacturer. 🎧
Key Points
This speaker cable includes four individually insulated conductors that are color coded to simplify polarity identification during installation. The conductors are manufactured from high-purity copper to reduce resistance and preserve audio clarity over runs up to 100 feet. The white PVC jacket provides a neat appearance for installations that require a visible run or termination at wall plates. 🔌
Technical Specifications
- Name: Monoprice 104037 Access Series 12 Gauge 4-Conductor Speaker Wire
- Conductor material: 99.9% oxygen-free pure bare copper
- Gauge: 12 AWG, 4 conductors
- Jacket: White PVC
- Length: 100 ft
- Rating: CL2 for in-wall fire safety
Usage Recommendations
Run the cable through walls and cavities following local electrical and building codes, and use the color-coded insulation to keep positive and negative terminals consistent at each speaker and amplifier. For best results in longer runs, keep connections tight and use proper wall plates or terminal blocks to avoid stray contact. Consider that PVC jackets are durable for indoor use but may not be suited for direct burial or exposure to outdoor elements. ⚠️
Positive Aspects
The four-conductor design allows for bi-amping or easier multi-speaker setups without additional parallel runs. The CL2 rating is a practical safety feature for fixed in-wall wiring, and the white finish helps the cable blend into usual wall and trim colors. The oxygen-free copper composition is intended to lower signal loss and maintain frequency response across mid and high ranges. 🎵
Note that while the CL2 rating covers many residential in-wall applications according to the manufacturer, some commercial installations require higher fire ratings or conduit use. Also keep in mind that PVC jackets add flexibility and protection but are less UV resistant than outdoor-rated alternatives.
