Description Shipping information

The JBL Apex PA1254 is the high-output big brother of the Apex series. While it maintains the same ultra-compact footprint as its smaller siblings, it nearly doubles the power, making it the ideal choice for driving high-performance marine speakers or even a pair of subwoofers in a space-constrained environment.

Serious Power, Minimal Footprint

The "1254" stands for its massive 1250W Peak Power capability. Despite being smaller than a shoe, this amp is a powerhouse:

  • High-Output Class D Efficiency: Delivers a clean 75W RMS x 4 at 4 ohms, or a punchy 125W RMS x 4 at 2 ohms.

  • Bridgable for Versatility: Need to power a sub? Bridge the channels to get 250W RMS x 2 at 4 ohms. This allows you to run a "3-channel" setup (two speakers + one subwoofer) with ease.

  • Ultra-Compact Aluminum Chassis: Measures only 170mm x 85mm x 45mm, allowing it to fit into storage cubbies, under consoles, or behind fairings where traditional amps simply can't go.

Marine-Grade Touches

Like all Apex units, the PA1254 is built to withstand "worst-case scenario" weather:

  • Marinized Protection: Features a conformal-coated PCB to prevent corrosion from salt air and moisture.

  • Harman Torture-Tested: Every unit is subjected to UV-light blasting, salt spray, and extreme temperature cycling (freezing and baking) to ensure it won't fail when you're miles from the dock.

  • Weather-Resistant Control Cover: A removable plate protects the gain and crossover settings from direct water contact and accidental adjustments.

Why Choose the PA1254 over the PA454?

If you are running premium speakers (like the JBL Club or Stadium Marine series) or if you want the option to add a subwoofer later, the PA1254 is the better investment. The extra "headroom" ensures your music stays crystal clear at high volumes, even over the roar of a 300HP outboard engine.
