Description
SLA-M 60.4 - Compact Marine Power for Demanding Powersports Systems
The SLA-M 60.4 is a super mini waterproof amplifier built for tight marine and powersports installations where space, durability, and clean output all matter. Its compact chassis keeps installation flexible while the marine-ready protection helps it stand up to wet, exposed environments.
- Efficient Class D performance: Class D design gives the SLA-M 60.4 strong output in a small footprint, making it a practical match for boats, UTVs, and other compact audio builds.
- Power matched to real systems: 90 Watts x 4 at 2 ohms; 60 Watts x 4 at 4 ohms; 180 Watts x 2 bridged at 4 ohms.
- System tuning control: crossover and filter ranges include 20Hz - 4kHz, with 0.26V - 5V input sensitivity.
- Marine-ready construction: IP65 protection helps protect the amplifier in exposed installations, while RCA/high-level input support keeps system integration straightforward.
- Compact installation: the chassis measures 3.9 x 3.3 x 1.6 (in) / 100 x 85 x 40 (mm), with T.H.D. 90dB.
The SLA-M 60.4 is designed for builders who need compact marine-grade amplification without giving up practical tuning, clean signal handling, or installation flexibility.
