Common Concerns Answered
Will the 400W total power be enough for my speaker setup?
The MS-AM402 delivers 200W RMS per channel at 2 ohms, or a bridged 400W RMS at 4 ohms. This output is sufficient for most 6.5" or 7.7" component speakers and many 10" subwoofers. For exceptionally large or high-excursion speaker systems requiring significantly more than 200W per channel, a higher-output amplifier may be necessary.
I've heard about units failing prematurely. What's the reliability?
While isolated incidents can occur with any electronic component, the Fusion MS-AM402 is constructed with marine-grade materials and conformal coated circuitry specifically to combat the corrosive marine environment. Proper installation, including correct wiring, fusing, and mounting, is crucial for ensuring long-term operational reliability and preventing potential failures.
Is this amplifier truly built to withstand the marine environment?
Absolutely. The MS-AM402 features a marine-grade chassis with stainless steel end caps and bottom plate, coupled with conformal coated circuitry. This robust construction provides superior resistance to corrosion from salt air and moisture, making it a reliable choice for offshore and coastal applications.
