About Shenzhen HIH Electronic Technology Co., Ltd. - Car Audio & Visual Systems Supplier in China

Based in China, Shenzhen HIH Electronic Technology Co., Ltd. currently lists five active products in its catalogue. The company focuses on the Car Audio & Visual Systems segment, offering both amplifiers and power stabilizers for automotive applications. Its amplifier lineup includes a 2‑channel class‑AB car hi‑fi amplifier and a 3‑channel class‑A/B car hi‑fi amplifier. The power stabilizer series comprises units rated at 1500 W, 2000 W and 3000 W, designed to protect car audio installations from voltage fluctuations. All items are classified under electronic equipment intended for vehicle use.

Class‑AB and class‑A/B amplifiers are standard in the aftermarket, delivering low total harmonic distortion (typically ≤0.1 %) and signal‑to‑noise ratios above 90 dB. These devices usually operate from a 12 V DC automotive power source and are built to meet automotive vibration and temperature standards such as ISO 16750. Power stabilizers of 1500‑3000 W are employed to maintain steady voltage during high‑demand audio peaks, often featuring voltage regulation within ±5 % and surge protection. In the automotive sector, such equipment is frequently installed in passenger cars, SUVs, and light trucks, where reliable audio performance is a selling point. The five listed products represent the core of Shenzhen HIH’s current offering for global car‑audio distributors.

Product Range and Specialties of Shenzhen HIH Electronic Technology Co., Ltd.

Shenzhen HIH’s catalogue currently contains a 2‑channel class‑AB car hi‑fi amplifier, a 3‑channel class‑A/B car hi‑fi amplifier, and three power stabilizer models rated at 1500 W, 2000 W and 3000 W. All amplifiers are designed for 12 V automotive systems and target the aftermarket segment where installers seek compact, multi‑channel solutions. The stabilizers are positioned as auxiliary units to safeguard audio head‑units and sub‑woofers from voltage spikes during engine load changes. Materials typically include aluminum heat‑sinks, polymer enclosures, and automotive‑grade capacitors, which align with the supplier’s product descriptions.

In the car‑audio market, amplifiers are commonly graded by power output per channel (e.g., 50 W RMS) and efficiency class, with class‑AB offering a balance between linearity and heat generation. Buyers often require compliance with CE marking and RoHS restrictions on lead and mercury, as well as FCC Part 15 for electromagnetic emissions. Power stabilizers for automotive use typically meet IEC 61000‑4‑11 surge immunity standards and are tested for operation across a temperature range of - 40 °C to +85 °C. Standard packaging includes anti‑static poly‑bags within corrugated boxes, stacked on pallets sized for 20‑ft containers.

Trade and Export Information - Shenzhen HIH Electronic Technology Co., Ltd.

Car‑audio amplifiers and power stabilizers manufactured in China are exported globally, with major import volumes directed to North America, Western Europe, and Southeast Asian markets. Importers in these regions usually process the goods under HS Chapter 85, which covers electrical machinery and equipment, and they often request CE, RoHS, and FCC documentation. Logistically, the products’ compact size and weight allow consolidation into 20‑ft or 40‑ft containers, typically loading 1,200 kg of amplifiers or up to 2,000 kg of stabilizers per container. Customs authorities frequently inspect for compliance with the EU’s Restriction of Hazardous Substances (RoHS) and the United States’ FCC Part 15 limits on radiated emissions.

Chinese exporters of automotive audio equipment benefit from established supply‑chain hubs in Guangdong province, where Shenzhen’s proximity to ports such as Yantian facilitates sea freight. Export documentation commonly includes a commercial invoice, packing list, certificate of origin, and test reports confirming voltage regulation and THD performance. Buyers typically negotiate Incoterms such as FOB Shenzhen or CIF destination port, depending on their logistics preferences. While Shenzhen HIH does not list specific certifications, international buyers should verify that the supplied units meet the regulatory standards mentioned above before shipment.

Sourcing from Shenzhen HIH Electronic Technology Co., Ltd. - Buyer Guidance

When sourcing amplifiers from Shenzhen HIH, buyers should request the unit’s RMS power rating per channel, total harmonic distortion measurement, and a compliance test report for CE and FCC. A sample unit can be requested to evaluate enclosure durability and thermal performance under continuous load. Confirm that the supplied power stabilizers include voltage regulation specifications, surge protection ratings, and an IEC 61000‑4‑11 test certificate.

Buyers should also verify the presence of a RoHS declaration and, if required for European markets, an EU‑type examination certificate. Packaging details such as pallet dimensions, weight per carton, and moisture barrier film should be clarified to avoid damage during sea transit. Before finalizing the order, request a detailed pro‑forma invoice indicating the chosen Incoterm and any required pre‑shipment inspection.

What types of car audio amplifiers does Shenzhen HIH offer?

The supplier lists a 2‑channel class‑AB car hi‑fi amplifier and a 3‑channel class‑A/B car hi‑fi amplifier, both intended for 12 V automotive systems. These amplifiers are designed to deliver low distortion and are suitable for aftermarket installation in passenger vehicles.

What power capacities are available for the power stabilizers?

Three stabilizer models are listed with continuous ratings of 1500 W, 2000 W and 3000 W. They are intended to maintain stable voltage for high‑power audio setups and typically include surge protection features.

Which certifications should a buyer request for these electronic products?

Buyers should request CE marking and a RoHS compliance declaration for both amplifiers and stabilizers. Additionally, FCC Part 15 test reports are common for amplifiers, while IEC 61000‑4‑11 surge immunity certification is typical for power stabilizers.

What are the usual minimum order quantities (MOQs) for the amplifiers and stabilizers?

In the automotive audio market, MOQs often start at a full pallet load, roughly 1,200 kg for amplifiers or 2,000 kg for stabilizers, depending on packaging. Exact quantities should be confirmed with Shenzhen HIH prior to order placement.

How are the products packaged for international shipment?

Each unit is placed in an anti‑static poly‑bag and then boxed in reinforced corrugated packaging. Boxes are stacked on standard 1,200 mm × 1,000 mm pallets, allowing efficient loading into 20‑ft or 40‑ft containers.

Which Incoterms are commonly used for shipping from Shenzhen?

Buyers typically negotiate FOB Shenzhen when they arrange their own freight forwarder, or CIF to a destination port if they prefer the supplier to handle freight and insurance. The chosen term should be reflected in the pro‑forma invoice.
