Can I use standard car audio power cables in a boat?

Yes, some car audio power cables can be used in a boat, but it is important to check that they are suitable for the marine environment.

A cable that works well in a car is not automatically the best option in a boat.

What is the difference between standard and marine cables?

Marine cables are often designed to better withstand moisture, corrosion and other stresses.

For example, they may have tinned copper conductors and insulation suitable for marine use.

Tinned copper means the copper conductors have a thin layer of tin that helps protect against corrosion.

Can I use OFC cable?

Yes, OFC cable consists of copper with a low oxygen content and has good electrical conductivity.

However, this does not automatically mean the cable is suitable for marine use.

Tinned copper cable with suitable insulation is often a better option in environments where the cable is exposed to moisture or salt.

Can I use CCA cable?

CCA stands for Copper Clad Aluminium and means the cable has an aluminium core with a thin copper layer.

CCA has higher electrical resistance than pure copper and therefore requires different sizing considerations.

For marine installations, copper cable intended for that environment is normally recommended.

What should I consider when routing cables?

• Size the cable according to current consumption and cable length.

• Use correct fuse protection.

• Protect cables against abrasion and mechanical damage.

• Use suitable cable lugs and connections.

• Protect connections against moisture and corrosion.

• Follow the manufacturer’s installation instructions.

Important: Cable length has a major influence in low-voltage systems. Cables that are too long or too thin can cause voltage drop that affects the equipment’s operation.
