MaxLouder 12V 150dB Super Loud Car Horn Compressor Kit — Black, Compact Train-Style 180W Weatherproof

The MaxLouder 12V 150dB super loud car horn compressor kit is a compact, chrome-plated air pump and compressor that delivers a powerful 150 dB train-style horn for almost any vehicle without a separate air tank.

This compact compressor kit combines a non-rusting chrome zinc alloy housing with upgraded copper windings to produce a loud, stable horn tone while occupying minimal space. Designed for 12V systems, it installs quickly using the included mounting hardware and works straight out of the box — no additional air system or tank required. Weatherproofing features let it endure road and marine conditions, making it a practical upgrade for drivers and riders who need a reliable, attention-grabbing signal.

How loud is this horn and will it fit my vehicle?

The MaxLouder compressor is rated at about 150 dB at the source, producing a train-style trumpet sound that is far louder than factory horns. Its universal 12V design fits cars, trucks, SUVs, motorcycles and boats, so compatibility is broad. Because it’s a self-contained compressor, you don’t need an external air tank or complex plumbing.

• Output: approximately 150 dB sound pressure
• Voltage: 12V, Power 180W
• Fits: passenger cars, trucks, SUVs, motorcycles, boats
• No external air system required

What are the build quality and weatherproofing details?

The compressor uses chrome-plated zinc alloy to resist corrosion and a rubber dust cover over the air head to keep out moisture and debris. Internally, upgraded copper wire terminals and a copper coil help ensure stable conductivity and longer life under load. The design emphasizes durability for outdoor and marine use without sacrificing sound performance.

• Material: chrome-plated zinc alloy (non-rusting finish)
• Rubber dustproof cover for the air head
• Upgraded copper coil and terminals for better conductivity
• Rated to operate in harsh environments

How easy is installation and what electrical draw should I expect?

Installation is straightforward: mount the compressor using the included hardware, wire it to a 12V source and connect the horn output. The unit draws about 15A at no-load and up to roughly 20A under load; power ratings are 180W, so use appropriately rated wiring and a fuse. Because there’s no separate tank, setup time is shorter than traditional air-horn systems.

• No separate air tank needed — direct-mount compressor
• No-load current: ~15A; load current: ~20A
• Power: 180W, recommended fuse and wiring size required
• Mounting hardware included for quick fitment

What warranty and after-sale support does MaxLouder provide?

MaxLouder offers a one-year replacement warranty aimed at customer satisfaction. If the compressor fails under normal use within the warranty period, the company will replace it. Always follow the provided installation instructions and retain purchase information for claims.

• 1-year replacement warranty
• Support available for installation questions
• Keep receipt and installation notes for warranty claims
