It is intended to give an aftermarket system more hands-on tonal adjustment than a typical head unit provides. Front, rear, and subwoofer outputs support systems using separate amplifiers for speaker zones and bass.\u003c\/p\u003e\u003cp\u003eThis equalizer is suited to listeners building or refining a multi-amplifier vehicle audio system, as well as installations retaining a factory radio with speaker-level outputs. It accepts RCA\/CD input, high-level speaker input, and a front-mounted 3.5 mm auxiliary input. An input selector lets the user choose the connected source rather than relying on a single source connection.\u003c\/p\u003e\u003cp\u003eSeven center frequencies cover low bass through upper treble: 50 Hz, 125 Hz, 315 Hz, 750 Hz, 2.2 kHz, 6 kHz, and 16 kHz. Each band offers up to 12 dB of cut or boost for targeted tonal changes. Separate master-volume, front-to-rear fader, and subwoofer-level controls provide straightforward system-level adjustment.\u003c\/p\u003e\u003cp\u003eThe built-in line-driver stage is specified to deliver more than 9 volts of maximum output through the RCA outputs. This can help provide a stronger preamp-level signal to compatible external amplifiers. The unit also includes selectable 60 Hz, 80 Hz, and 120 Hz subwoofer low-pass settings, with 12 dB-per-octave crossover slopes.\u003c\/p\u003e\u003cp\u003eThe HFEQ7 fits into an upgrade path between the radio or media source and external amplifiers. Its half-DIN chassis can be mounted in or under the dash when suitable clearance is available. With front, rear, and subwoofer outputs, it can serve as a central control point for a three-zone amplified audio system.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeven-Band EQ:\u003c\/strong\u003e Adjusts seven fixed frequency ranges from bass through treble.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e9-Volt Line Driver:\u003c\/strong\u003e Supplies a high-output preamp signal through the RCA outputs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree Input Types:\u003c\/strong\u003e Supports RCA, speaker-level, and front 3.5 mm auxiliary sources.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActive Crossover Outputs:\u003c\/strong\u003e Provides filtered front, rear, and subwoofer signal paths.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelectable Subwoofer Crossover:\u003c\/strong\u003e Chooses 60 Hz, 80 Hz, or 120 Hz low-pass points.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Level Controls:\u003c\/strong\u003e Includes master volume, subwoofer level, and front-to-rear fader controls.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe HFEQ7 uses a compact half-DIN chassis with illuminated blue control knobs and a front-panel auxiliary input. Its layout places equalizer sliders and primary level controls within reach for in-dash or under-dash use. Mounting hardware is included for installation.\u003c\/p\u003e\u003cp\u003eConnect the unit between the source unit and external amplifiers, using RCA input when available or the high-level input with a factory-radio speaker output. Use the front, rear, and subwoofer RCA outputs for their respective amplifier channels, and connect constant or switched +12-volt power through a 2-amp in-line fuse, chassis ground, and a remote-turn-on lead. Confirm mounting depth and route power, signal, and remote wiring away from moving parts before final installation.\u003c\/p\u003e","brand":"Hifonics","offers":[{"title":"Default Title","offer_id":45631922798662,"sku":"HFEQ7","price":97.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/81ykpyYOVYL.jpg?v=1784389501","url":"https:\/\/audiowatt.store\/products\/hifonics-hfeq7-7-band-half-din-car-audio-equalizer","provider":"Audio Watt Store","version":"1.0","type":"link"}
