Stinger Audio MT-600.4 1000W RMS Compact 4-Channel Amplifier

In this review the Stinger Audio MT-600.4 is presented as a compact, high-efficiency 4-channel car amplifier best suited for drivers who need reliable multichannel power in limited space. The single biggest reason to consider it is the combination of a Digital Class-D power stage with advanced HEXFET MOSFETs that deliver strong output while keeping heat and size down, making it a practical choice for installs where space and power efficiency matter.

Key Features

• Digital Class-D: Provides high efficiency and tight power delivery, so the amp can run cooler in confined installations without sacrificing output.
• Compact and Sturdy Design: The small form factor and rugged construction make it easier to mount under seats or in tight trunks while standing up to road vibration.
• Robust Unregulated Power Supplies: Designed to deliver consistent performance and efficient power transfer for steady output across channels.
• Advanced HEXFET Power MOSFET: Uses reduced on-resistance and faster switching speeds to improve reliability and electrical efficiency under load.
• Direct Insert Terminals: Power and speaker terminals are designed for lower resistance connections, which helps maximize delivered power and reduce voltage loss.
• Crossover Filters: Built-in high-pass and low-pass filters allow running tweeters or midrange speakers without an external crossover for simpler system integration.

Who It's For

This amp is aimed at enthusiasts and installers who want a compact 4-channel amplifier to power a full car audio setup-driving front and rear speakers or powering a set of mids and a pair of tweeters with bi-amping options. It suits vehicles with limited amplifier mounting space and owners who prioritize efficiency and reliable build quality.

Customers who need ultra-high-end audiophile refinement or a fully regulated power supply for extreme power tuning may prefer a larger, more specialized amplifier. Also, those sensitive to any potential distortion at very high volumes should audition the amp in their vehicle before committing.

Pros & Cons

Pros

• Compact footprint and sturdy construction that make flexible mounting straightforward.
• Efficient Digital Class-D design combined with HEXFET MOSFETs for strong power with lower heat.
• Built-in high-pass and low-pass crossovers remove the need for extra external components in many installs.
• Direct insert power and speaker terminals lower resistance for better power transfer.

Cons

• Some listeners report occasional distortion at extreme volumes, so high-output systems should be tested prior to purchase.
• Unregulated power supplies may not suit setups that require perfectly stable voltage for highly tuned systems.
