Description

The Mercury 2 core figure-8 speaker cable combines 32 strands per conductor (16 copper + 16 copper-clad aluminium) in a flat parallel configuration with red and black PVC sheathing. Each conductor carries a 0.81mm² cross-sectional area and the cable is rated to 10A maximum current, making it suitable for low to medium power speaker runs, automotive wiring and general-purpose DC distribution where polarity identification matters.

Designed for automotive audio installations, home speaker wiring and 12V/24V DC systems, the figure-8 profile sits flat against surfaces and feeds easily through vehicle door jambs, under carpets and along skirting boards without the bulk of round twin-core cable. The red/black colour coding provides instant polarity identification during installation, reducing wiring errors in multi-speaker setups or automotive harnesses where swapped polarity causes phase cancellation or reversed fan direction.

The mixed copper/CCA conductor construction balances conductivity with cost and weight. Pure copper strands carry the bulk of the current while CCA strands add mechanical strength and reduce material cost on longer runs. The 3.2 x 6.4mm overall dimension keeps the cable low-profile while the PVC sheath provides abrasion resistance against vehicle bodywork, carpet backing and timber edges. Supplied on a 100m reel, the cable can be cut to length on site without waste.

Frequently Asked

What's the maximum power this cable can handle for speakers?

At 10A maximum current and typical 4-8 ohm speaker impedances, the cable handles speaker runs up to approximately 80-160W per channel on home audio systems, and higher wattages on automotive 12V systems where voltage is lower. For home hi-fi above 100W per channel or runs longer than 10m, consider stepping up to a larger CSA cable to minimise power loss.

Can this be used for mains voltage applications?

No. The cable is designed for low-voltage DC applications (automotive 12V/24V, speaker-level audio signals, low-voltage LED lighting). It does not carry mains voltage ratings or certifications and must not be used on 230V AC circuits.

What's the difference between copper and copper-clad aluminium strands?

Copper strands offer higher conductivity and carry most of the current. Copper-clad aluminium (CCA) strands have an aluminium core with a thin copper coating, reducing weight and material cost while adding mechanical strength. The mixed construction is common in automotive and budget speaker cable where pure copper would add unnecessary cost on longer runs.

How is the cable terminated?

For automotive and speaker applications, the cable is typically stripped back 6-8mm and crimped into ring terminals, spade terminals or bootlace ferrules, or soldered directly to terminal posts. The stranded construction makes it flexible enough to wrap around screw terminals on older speaker binding posts.
