Description
MMATS Pro Audio LSX Series Amplifiers
LSX covers the high-output part of the MMATS amplifier lineup, from compact multi-channel power for mids/highs to very large mono power for subwoofer systems. The family now includes 4-channel, 2-channel and mono models so the system can stay within one amplifier platform as power requirements grow.
Match LSX output to the complete electrical system: A multi-channel LSX amplifier serves a different job from a mono subwoofer model. Use multi-channel LSX models where several full-range or mid/high amplifier channels are needed, and mono LSX models for dedicated subwoofer power. For 4K/8K/12K builds, verify alternator, battery, cable, fusing and supported impedance before quoting. For in-store product matching and a turnkey installation quote, contact SMS Car Audio.
Current LSX lineup
- 4-channel: LSX600x4, LSX900x4, LSX1400x4, LSX2600x4
- 2-channel: LSX4000.2D
- Mono: LSX1000.1D, LSX2000.1D, LSX4000.1D, LSX8000.1D, LSX12000.1D
Why we use LSX: the line gives us useful power steps without forcing a small system into an oversized amplifier or a large system into multiple undersized amps. The larger models are intended for systems where electrical support is planned from the start.
What matters before choosing one
- Electrical: the 4K, 8K and 12K mono models demand serious alternator, battery, cable and fuse support.
- Impedance: final speaker/sub wiring determines which model makes sense and how hard the charging system will be loaded.
- System role: use the multi-channel models for full-range/mid-high duty and the .1D models for dedicated subwoofer power.
- Warranty: the 2026 MMATS dealer sheet lists LSX with a 1-year warranty.
In-store / quote-only product. SMS Car Audio matches the amplifier to the vehicle, speakers/subwoofers, final impedance and electrical system before sale.
Where this fits in the build
An amplifier should be chosen around the channels, load, speaker or subwoofer plan, available electrical support and how hard the system needs to play.
