Car Audio and Home Amplifier Parts
Die cast heatsink housings and structural parts for car audio and home amplifier products, combining thermal dissipation with a finished exterior surface.
Product Overview
Housing and Heatsink in One Casting
Car amplifiers and home amplifiers need a rigid, attractive enclosure that also removes heat from the output devices. A die cast body performs both roles, and by machining the mounting faces and fins accurately we ensure the thermal path from device to ambient is as short and effective as the design allows.
Zhigao is a manufacturer of car audio and home amplifier parts serving customers in Europe, North America and Asia. Every order is produced to your drawing and inspected against your specification before shipment, with full documentation supplied.
