It can drive four speakers in stereo or support bridged channel pairs for higher-power applications. This makes it suitable for upgrading factory or aftermarket speaker systems while retaining control over system configuration.\u003c\/p\u003e\u003cp\u003eWith output ratings of 4 x 185 watts at 4 ohms and 4 x 375 watts at 2 ohms, the GP-1500.4 is built for systems using compatible full-range speakers. It can also bridge into two 4-ohm loads at 750 watts per channel pair. The amplifier supports four-channel stereo, dual stereo bridged, stereo plus bridged mono, and dual bridged mono operating modes.\u003c\/p\u003e\u003cp\u003eThe built-in variable electronic crossover helps tailor the signal sent to connected speakers. Selectable full-range, high-pass, and low-pass modes allow installers to configure channel pairs for component speakers, coaxial speakers, or compatible subwoofer duty. Variable high-pass and low-pass controls cover a 40 to 400 Hz range.\u003c\/p\u003e\u003cp\u003eThe amplifier accepts both RCA low-level and speaker-level inputs, providing connection options for aftermarket receivers and many factory audio systems. Its adjustable 0.2 to 9V input sensitivity range supports level matching to the source unit. A low-noise preamplifier circuit is used ahead of the amplifier section.\u003c\/p\u003e\u003cp\u003eCrunch equips the GP-1500.4 with SPEED-FET MOSFET output components, a pulse-width-modulated power supply, and an aluminum heat sink using Quick Thermal Dispersion technology. Switchable bass boost provides 0, +6, or +12 dB settings. The compact chassis can serve as the power stage for a four-speaker upgrade or a mixed system using stereo speakers and bridged channels.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour-Channel Design:\u003c\/strong\u003e Powers up to four speakers from one chassis.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-Ohm Stable Outputs:\u003c\/strong\u003e Delivers 375 watts per channel at 2 ohms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBridged Channel Pairs:\u003c\/strong\u003e Provides two 750-watt outputs into 4 ohms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Electronic Crossover:\u003c\/strong\u003e Select high-pass, low-pass, or full-range operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh- And Low-Level Inputs:\u003c\/strong\u003e Connects with factory or aftermarket source units.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitchable Bass Boost:\u003c\/strong\u003e Offers 0, +6, and +12 dB settings.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe GP-1500.4 uses a black and red aluminum heat-sink chassis with Class A\/B circuitry. Its power section incorporates a high-energy PWM power supply and SPEED-FET MOSFET components. Nickel-plated brass terminals with screw-down connections provide the amplifier's power and speaker connection points.\u003c\/p\u003e\u003cp\u003eMount the amplifier in a secure, ventilated location away from moisture and excessive heat. Use up to 4 AWG power and ground wire, use speaker wire up to 12 AWG at the amplifier terminals, and protect the power connection with appropriate fusing. Configure each channel pair for full-range, high-pass, or low-pass use, and maintain a 2-ohm minimum load per unbridged channel or a 4-ohm minimum load when bridged.\u003c\/p\u003e","brand":"Crunch","offers":[{"title":"Default Title","offer_id":45623991664710,"sku":"GP-1500-4","price":139.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71JMGioEtNL.jpg?v=1784373086","url":"https:\/\/audiowatt.store\/products\/crunch-gp-1500-4-4-channel-car-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
