Its compact footprint helps solve the common challenge of finding room for an amplifier in space-limited installations. It can power four full-range speakers or be configured for two bridged channels.\u003c\/p\u003e\u003cp\u003eWith 75 watts RMS per channel at 4 ohms, the PA1254 is suited to driving compatible speakers with controlled, full-range output. It delivers 125 watts RMS per channel at 2 ohms, while bridged operation provides 250 watts RMS to each of two 4-ohm loads. Separate front and rear level controls support balanced system tuning.\u003c\/p\u003e\u003cp\u003eThis amplifier is built for systems exposed to demanding outdoor conditions. Its ultra-compact aluminum chassis and conformal-coated circuit board support use in marine and powersports environments. The Class D design provides efficient power delivery in a small enclosure.\u003c\/p\u003e\u003cp\u003eFlexible crossover controls allow the PA1254 to fit a range of speaker and subwoofer layouts. The front channels offer selectable full-range or high-pass operation, while the rear channels add selectable low-pass capability. Crossover points at 60, 80, and 120 Hz help divide frequencies between speakers and a subwoofer.\u003c\/p\u003e\u003cp\u003eBoth low-level RCA and high-level speaker inputs are provided for integration with aftermarket or factory-style source units. High-level installation can use the included adapters and the amplifier's DC-offset signal sensing turn-on feature. This makes the PA1254 a practical foundation for upgrading a four-speaker system or building a compact multi-channel setup.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour-Channel Class D Power:\u003c\/strong\u003e Supplies efficient amplification for compatible full-range speakers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e75W RMS Per Channel:\u003c\/strong\u003e Delivers rated output at 4 ohms across four channels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBridgeable Channel Pairs:\u003c\/strong\u003e Supports two-channel bridged operation at 4 ohms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelectable Crossovers:\u003c\/strong\u003e Helps match amplifier output to speakers or subwoofers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh- And Low-Level Inputs:\u003c\/strong\u003e Connects with speaker-level or RCA source signals.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConformal-Coated Circuit Board:\u003c\/strong\u003e Adds protection for demanding outdoor installations.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe PA1254 uses an ultra-compact aluminum chassis measuring 9.53 inches wide, 1.75 inches high, and 3.3 inches deep. Its conformal-coated PCB is intended for harsh-condition use, while the compact enclosure supports mounting where larger amplifiers may not fit. Power and protection indicators provide operating-status feedback.\u003c\/p\u003e\u003cp\u003eInstall the amplifier in a secure location with ventilation, avoiding a heat-sink-down orientation. Use 10 AWG power wiring, a properly fused battery connection, and a solid chassis or battery-negative ground connection. For low-level input, connect RCA cables and a remote turn-on lead; for high-level input, use the supplied adapters and set the input selector to HI.\u003c\/p\u003e","brand":"JBL","offers":[{"title":"Default Title","offer_id":45632131924038,"sku":"JBLPA1254","price":289.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71XHaYkKkbL.jpg?v=1784395716","url":"https:\/\/audiowatt.store\/products\/jbl-jblpa1254-4-channel-powersports-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
