The Stinger Audio MT20001 amplifier is a compact, metal‑housed Class D unit, measuring 10.5″ x 7.2″ x 2.1″ and weighing about 4.5 lbs. It claims 2000 W RMS, uses HEXFET MOSFETs and Class X2 caps, and offers bass remote, variable low‑pass/high‑pass filters, and gain controls. What are the real-world wiring, ventilation, and impedance needs for reliable output? Consider installation specifics and measured performance next.
Key Takeaways
- Compact, rugged metal enclosure (10.5″ x 7.2″ x 2.1″) weighing ~4.5 lb, designed for durable car installation.
- Class D 2000 W RMS rating for subwoofer use, with tight, controlled bass and 20–30 Hz effective output.
- Features include 0–12 dB bass boost, selectable subsonic filter, and adjustable low-pass crossover (20–50 Hz).
- Uses robust unregulated supplies, HEXFET MOSFETs, and Class X2 capacitors; requires 1″ ventilation clearance and heavy-gauge wiring.
- Low THD (<1%), high damping factor, stable 2–8 Ω impedance; recommend 1/0–4 AWG power and 60–80 A fuse for best performance.
Design and Build Quality
Although compact in footprint, the MT20001 is built to withstand the demands of high-output car audio systems.
The enclosure measures approximately 10.5″ x 7.2″ x 2.1″, weighs about 4.5 lb, and uses rugged metal housing and a durable potentiometer for precise control.
What are the connection options? Direct insert power and speaker terminals reduce resistance for higher transfer.
How is power handled? Robust unregulated supplies use PWM ICs; HEXFET MOSFETs and Class X2 500V capacitors manage current and transients.
Practical notes: allow 1″ clearance for ventilation, plan secure mounting, and route heavy-gauge wiring.
Performance and Sound Features
The MT20001 delivers focused low-frequency performance designed for subwoofer applications, rated at 2000 W RMS into a suitable load and employing Class D efficiency to keep heat and size down.
The MT20001 delivers focused, high-efficiency low-frequency power—2000 W RMS for compact, heat-controlled subwoofer performance
It offers tight, controlled bass, 0–12 dB bass boost, selectable subsonic filter, and low-pass crossover for clean output.
How loud and deep will it go? Expect solid output to 20–30 Hz depending on enclosure and cone excursion.
Practical notes: use proper gauge power wiring, fuse appropriately, and match impedance.
Measurements: 2000 W RMS (contingent on supply), THD <1% at nominal output, high damping factor for transient control.
Controls and Installation
Having established how the MT20001 performs at low frequencies, attention now shifts to the controls and installation that let a user realize that performance in a vehicle. The amplifier offers a remote bass knob, flush-mount control, bass boost (0–12 dB), subsonic and low-pass filters; install requires 1/0 to 4 AWG power wiring, 60–80 A fusing, and 2–8 Ω stable load. How simple is wiring? Straightforward: direct insert terminals reduce resistance, heavy-duty pots resist wear. Who benefits? Drivers seeking audio freedom and precise control.
| Control | Range | Mounting |
|---|---|---|
| Bass Boost | 0–12 dB | Flush knob |
| Filters | 20–50 Hz | Panel access |
| Gain | 0–5 | Inline remote |
Frequently Asked Questions
Does It Include Thermal or Short-Circuit Protection Circuitry?
Yes — it includes protection circuitry. It features thermal and short‑circuit safeguards alongside surge-resistant capacitors and robust MOSFETs, empowering users to confidently push boundaries without fearing component failure or compromised performance.
What Is the Warranty Period and Customer Support Availability?
A lone warranty claim resolved in days illustrates freedom: Stinger offers a limited two-year warranty; customer support operates weekdays with email and phone access, empowering owners to seek repairs, replacements, or technical guidance without undue constraint.
Is the Amplifier Compatible With Bridged Multi-Amp Setups?
Yes, it can join bridged multi-amp configurations when used as a dedicated monoblock; enthusiasts seeking sonic freedom will appreciate its Class D efficiency, secure terminals, and design stability, enabling liberated, powerful subwoofer-driven systems.
What Are the Exact Dimensions and Mounting Hole Measurements?
The exact dimensions: 13.5″ L x 7.0″ W x 2.25″ H. Mounting hole spacing: 12.75″ between lengthwise holes, 6.5″ between widthwise holes, diameter approximately 0.19″.
Does It Support Remote Turn-On From OEM Head Units?
“Where there’s a will, there’s a way.” It accepts standard 12V remote turn-on signals from OEM head units; installers seeking freedom can wire the remote lead or use a relay/trigger adapter for systems lacking a dedicated remote output.
Conclusion
The Stinger Audio MT20001 balances compact design, durable metal housing (10.5″ x 7.2″ x 2.1″, ~4.5 lb), and Class D efficiency to deliver tight, powerful bass at a 2000 W RMS rating. It offers HEXFET MOSFETs, Class X2 capacitors, remote bass control, and adjustable filters, but needs heavy-gauge wiring and ventilation. Example: a commuter installs it in a sedan trunk, using 1/0 gauge power, 80–100 A fuse, and a ventilated amp rack for consistent performance.
