Continuing a sweeping update of its amplifiers, MTX, recently unveiled new RTX amplifiers designed to match pro audio speakers and a new powersports amplifier line, the PS Series.
This follows MTX’s launch of new Thunder car and marine amplifiers last year and new Terminator amplifiers in 2024.
The RTX (Road Thunder Extreme) amplifiers are especially suited to working with MTX’s pro audio RTX speakers. They emphasize high-wattage capability and low-distortion performance, with power output up to 3,000 watts (see specs below). The line is due to ship around early January 2026.
RTX Series Specifications
Two Class D amplifiers with the following standard features:
- Variable low-pass and high-pass crossovers
- Adjustable bass boost (0-12dB at 45Hz)

- Thermal, overload, and short-circuit protection
- Built-in cooling fan and over-sized heatsink
4-Channel Amplifier RTX1600.4 Specs:
- 4Ω RMS Power Output: 250W x 4-channel
- 2Ω RMS Power Output: 400W x 4-channel
- 4Ω RMS Bridged Power Output: 800W x 2-channel
1-Channel Amplifier RTX3000.1 Specs:
- 4Ω RMS Power Output: 1000W x 1-channel
- 2Ω RMS Power Output: 2000W x 1-channel
- 1Ω RMS Power Output: 3000W x 1-channel
PS Series
The new PS powersports amplifier series has an iP67 waterproof rating and a small mounting footprint to suit UTVs and other powersports applications. The amplifiers are shipping with the following features and specs:
PS Series specifications:
- Fixed crossover points (low-pass at 80Hz, high-pass at 80Hz where applicable)
- RCA line-level inputs
- High Level Input capable via the RCA’s
- Auto turn-on via DC Offset or Remote
- Thermal and short-circuit protection
- Available in 1-channel, 2-channel, and 4-channel variations
- Configurations include 800 x 1-channel, 200 x 2-channel, 800 x 4-channel, 400 x 2-channel at 2-ohms
The 800 watt mono PS800.1 has a retail price of $499.95.
