Each zone provides low-voltage RCA outputs, with a stereo pair plus a mono subwoofer output per zone, so it feeds external marine amplifiers instead of driving speakers directly.\u003c\/p\u003e\u003cp\u003eFor planning fit behind the dash, the chassis measures 5.94 in x 3.90 in x 3.94 in (151 mm x 99 mm x 100 mm) with a mounting hole of 4.72 in x 3.25 in (120 mm x 83 mm). The front is rated IP67 for wet helm installs, but it should not be submerged or subjected to high-pressure spray.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e12V-only power requirement (10 to 15.9 VDC allowable) for negative-ground systems, with a 5A fuse and 1.5A maximum current draw\u003c\/li\u003e\n\u003cli\u003eFour-zone, 12-channel preamp output layout: a stereo pair plus mono subwoofer RCA outputs for each zone\u003c\/li\u003e\n\u003cli\u003eOutput modes per zone include Relative, Absolute, Fixed, or Off, with Fixed level options of 4V, 2V, or 1V RMS\u003c\/li\u003e\n\u003cli\u003eNMEA 2000 connection with LEN 1 using a Micro-C connector for network integration with compatible controllers and displays\u003c\/li\u003e\n\u003cli\u003eBluetooth audio streaming with Qualcomm aptX support, up to 35 ft (11 m) range, and pairing for up to 8 devices\u003c\/li\u003e\n\u003cli\u003eDual USB ports for media playback: USB 1 supports iPhone or USB storage with 2.1A charging, USB 2 supports USB storage with 500 mA output\u003c\/li\u003e\n\u003cli\u003eTwo stereo RCA AUX inputs with selectable 2V or 1V RMS input sensitivity\u003c\/li\u003e\n\u003cli\u003eAM\/FM tuner with RDS support, plus DAB+ tuning capability; SiriusXM support with a SiriusXM Connect tuner (sold separately)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and wiring\u003c\/h6\u003e\u003cp\u003eMount it in a location that stays ventilated and protected from direct, heavy spray. Power is a switched +12V feed (red) and ground (black), with the 5A fuse placed at the power connection point. There is also a +12V illumination input (orange) for tying into your dash lighting, and an amplifier remote turn-on output (blue) for triggering external amps.\u003c\/p\u003e\u003cp\u003eOn 24V boats, plan on a proper DC-DC conversion to a stable 12V supply before this unit. If your boat sees voltage sag at start-up or when heavy loads kick on, the built-in low-voltage alert behavior is a useful reminder to check battery condition, cabling, and charging system health.\u003c\/p\u003e\u003ch6\u003eAudio system planning\u003c\/h6\u003e\u003cp\u003eThis layout works well when your boat has separate listening areas that need different volume levels, like cockpit and cabin, or a tower and the main deck. Since each zone has its own RCA outputs, you can route signals cleanly to multiple amplifiers and keep wiring tidy in the helm and electronics bay. Zone naming and per-zone settings help keep control straightforward once the system is tuned.\u003c\/p\u003e\u003ch6\u003eConnections and day-to-day use\u003c\/h6\u003e\u003cp\u003eBluetooth is handy for quick playback from phones and tablets, while USB ports cover stored music and keep devices topped up. For hardwired sources, AUX 1 and AUX 2 accept standard stereo RCA inputs. If you run an NMEA 2000 backbone, the Micro-C connection makes it easy to place the stereo on the network so it can show up as a named device and integrate with compatible control options.\u003c\/p\u003e\u003cp\u003eThis unit is a good match for boaters building a multi-amp system where zone control matters, like cruisers with an interior cabin and an open cockpit, or fishing and tow boats that split speakers across helm, transom, and tower areas.\u003c\/p\u003e","brand":"JL Audio","offers":[{"title":"Default Title","offer_id":52256224116917,"sku":"QBP098712","price":786.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1284801_qbp098712.jpg?v=1771286676","url":"https:\/\/www.qualityboatparts.com\/products\/qbp098712","provider":"Quality Boat Parts","version":"1.0","type":"link"}
