{"title":"5-Channel Marine Amplifiers","description":"\u003cp\u003eA \u003cstrong\u003e5-channel marine amplifier\u003c\/strong\u003e is the most efficient way to power a complete boat audio system — four speakers and a subwoofer from a single amplifier, a single power run, and a single amplifier footprint. For boats where amp rack space is at a premium or where simplicity is more important than maximum output in each channel, a 5-channel is the definitive choice.\u003c\/p\u003e\n\n\u003ch3\u003eArchitecture: 4+1\u003c\/h3\u003e\n\u003cp\u003e5-channel marine amplifiers use a 4+1 architecture: four full-range channels for speakers and one high-power mono channel for a subwoofer. The mono channel typically gets more power than the sum of the four speaker channels — because bass requires more power to produce SPL than midrange and treble at the same perceived volume. A typical 5-channel marine amp might be rated at 75W × 4 for speakers and 500W × 1 for the sub.\u003c\/p\u003e\n\n\u003ch3\u003eWhat to Look For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndependent crossover on the mono channel\u003c\/strong\u003e — adjustable low-pass filter (typically 40–250 Hz sweep) lets you tune the sub's upper frequency limit to blend with your speakers\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHigh-pass filter on speaker channels\u003c\/strong\u003e — rolling off the bass from your coaxials protects them and lets the sub handle the low end cleanly; your speakers will play louder and cleaner when they're not trying to reproduce 40 Hz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInput sensitivity adjustment per channel group\u003c\/strong\u003e — lets you match input signal level from your head unit's preamp outputs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMarine-rated construction\u003c\/strong\u003e — conformal coating, corrosion-resistant hardware, designed for boat environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eOcean Rock Audio stocks 5-channel marine amps from Kicker, JL Audio, Fusion, and more.
