The Giyofom Bus Bar Power Distribution Block is an electronics accessory for car audio and vehicle power distribution that keeps wiring organised while handling high current reliably. Neat, robust connections bring peace of mind when fitting amplifiers or adding auxiliary systems. Will build quality and protection features meet the demands of installers and DIYers?
⚡ At a Glance
- • Current Capacity: 250A continuous rating with a thicker 3.5mm copper busbar
- • Best for: Car audio installers, vehicle wiring upgrades and small marine systems
- • Not ideal for: Users who require built-in fusing or switching for each circuit
Handles 250A continuous and is rated to a maximum of 300V AC or 48V DC. A premium brass contact plate, nylon base and detachable cover improve insulation and connection protection.
Safe high-current distribution – Thanks to a 3.5mm copper busbar
A 3.5mm copper busbar is thicker than common 2.0mm brass bars, which lowers electrical resistance and reduces heat under load. Continuous 250A capability is supported by the combination of the copper bar and robust contact surfaces.
Secure, low-resistance power delivery for high-demand amplifiers and auxiliary systems, with reduced risk of overheating during sustained use.
Secure multi-point connections – With four stainless steel studs
Four stainless steel studs accept multiple ring-terminals and provide strong mechanical and electrical contact. Stainless steel resists corrosion, a practical advantage for vehicle and marine environments.
Multiple power feeds or distribution runs can be attached cleanly and reliably, simplifying complex installations and improving long-term connection integrity.
Protected, insulated mounting – With nylon base and detachable cover
A nylon base offers electrical insulation while flame-retardant plastic around the base adds safety in confined installations. A detachable cover shields terminals from debris and accidental contact.
Reduced risk of shorts and accidental contact, plus neater presentation and safer routing when wiring in engine bays, boots or boats.
