The range covers a monoblock subwoofer amplifier, 4-channel models with and without Bluetooth, and a 6-channel model with staggered power for more involved speaker and subwoofer layouts.\u003c\/p\u003e\u003cp\u003eAll models use Class D amplification, operate from 9-16 VDC and have an IP67-rated amplifier body, excluding cables. That makes the series a practical fit for consoles, storage lockers, helm compartments and other protected boat locations where spray, salt air, vibration and tight mounting space are part of the installation.\u003c\/p\u003e\u003cp\u003eThe non-Bluetooth AP300\/1, AP300\/4 and AP600\/6 models include a built-in LCD display for manual control and can work with Fusion Audio app setup features when paired with a compatible Fusion head unit with built-in DSP. The Bluetooth AP200\/4BT adds direct smartphone audio streaming, an IP67-rated wired remote and AUX input source selection.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eMarine amplifier range with 1-channel, 4-channel and 6-channel configurations for subwoofer, speaker and mixed system layouts.\u003c\/li\u003e\n\u003cli\u003eClass D amplification keeps the chassis compact while supporting RMS power ratings from 200 watts to 600 watts, depending on the model.\u003c\/li\u003e\n\u003cli\u003e9-16 VDC operating range fits common 12 V marine electrical systems.\u003c\/li\u003e\n\u003cli\u003eIP67-rated amplifier body, excluding cables, for installations exposed to moisture, spray and dusty storage areas.\u003c\/li\u003e\n\u003cli\u003eIgnition-protected construction adds safety for marine and powersports installations where fuel vapors may be present.\u003c\/li\u003e\n\u003cli\u003eProtection circuits cover input under or over voltage, over temperature and output short circuit conditions.\u003c\/li\u003e\n\u003cli\u003eBuilt-in LCD control is included on the AP300\/1, AP300\/4 and AP600\/6 models for setup without relying only on hidden switches.\u003c\/li\u003e\n\u003cli\u003eBluetooth model includes a wired remote with IP67 rating and source selection for Bluetooth or AUX input.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThe JL Audio AP amplifier series is offered in four configurations so the amplifier can match the number of speakers, subwoofers and zones in the boat audio system.\u003c\/p\u003e\u003cp\u003eThe variants differ by channel count, Bluetooth availability, RMS power layout, chassis size and included control hardware. All four models use Class D amplification, operate from 9-16 VDC and have an IP67 rating for the amplifier body.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAP300\/1: 1 channel, Bluetooth: No. This monoblock version is for subwoofer duty, with 200 watts x 1 at 4 ohms or 300 watts x 1 at 2 ohms.\u003c\/li\u003e\n\u003cli\u003eAP300\/4: 4 channels, Bluetooth: No. This model works for four speaker channels or a bridged 2-channel layout, with 50 watts x 4 at 4 ohms or 150 watts x 2 when bridged at 4 ohms.\u003c\/li\u003e\n\u003cli\u003eAP600\/6: 6 channels, Bluetooth: No. This stepped-power model supports larger speaker layouts and mixed speaker plus subwoofer systems, with channels 5 and 6 carrying more power than channels 1 through 4.\u003c\/li\u003e\n\u003cli\u003eAP200\/4BT: 4 channels, Bluetooth: yes. This version adds direct Bluetooth audio streaming and includes a wired remote for source and control access away from the amplifier location.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eThe compact housings help when mounting space is limited behind the helm, inside a console or near an existing stereo system. The AP300\/1 and AP300\/4 measure 1.85 in x 10.43 in x 4.90 in, the AP600\/6 measures 1.85 in x 11.81 in x 5.90 in, and the AP200\/4BT measures 1.85 in x 7.28 in x 4.90 in.\u003c\/p\u003e\u003cp\u003ePlan power wiring, fuse protection and cable routing before mounting the amplifier. The AP300\/1, AP300\/4 and AP200\/4BT use a 35 A fuse rating, while the AP600\/6 uses a 70 A fuse rating. Keep signal cables and power cables routed cleanly to reduce noise and make future service easier.\u003c\/p\u003e\u003ch6\u003eSystem integration\u003c\/h6\u003e\u003cp\u003eThe RCA input range is switchable between 200 mV-2 VRMS for low-level input and 800 mV-8 VRMS for high-level input, which gives the installer flexibility when matching the amplifier to a marine stereo or source unit. The AP300\/1, AP300\/4 and AP600\/6 include variable crossover control from 20-500 Hz, depending on the channel layout, and all models include bass boost.\u003c\/p\u003e\u003cp\u003eThe AP200\/4BT is useful for small boats, tenders and simple cockpit audio systems where direct phone streaming is useful and a full stereo head unit may not be needed. For more integrated systems with Fusion DSP setup, the AP300\/1, AP300\/4 and AP600\/6 are the better fit within this range.\u003c\/p\u003e\u003ch6\u003eUse cases on board\u003c\/h6\u003e\u003cp\u003eThe AP300\/1 suits a dedicated marine subwoofer installation. The AP300\/4 fits a straightforward cockpit or cabin speaker system, while the AP600\/6 works for boats that need more channels or a speaker and subwoofer combination from one amplifier chassis.\u003c\/p\u003e\u003cp\u003eBoaters building a clean audio system in limited space, replacing an aging amplifier or adding power to a new set of marine speakers will get the most value from this series when the channel count and power layout are matched carefully to the speakers, impedance and wiring plan.\u003c\/p\u003e","brand":"JL Audio","offers":[{"title":"1 \/ No","offer_id":52715835195573,"sku":"QBP905520-V1","price":423.4,"currency_code":"USD","in_stock":false},{"title":"4 \/ No","offer_id":52715835228341,"sku":"QBP905520-V2","price":423.4,"currency_code":"USD","in_stock":false},{"title":"6 \/ No","offer_id":52715835261109,"sku":"QBP905520-V3","price":533.5,"currency_code":"USD","in_stock":false},{"title":"4 \/ yes","offer_id":52715835293877,"sku":"QBP905520-V4","price":465.75,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1340995_qbp905520.webp?v=1781720276","url":"https:\/\/www.qualityboatparts.com\/products\/qbp905520","provider":"Quality Boat Parts","version":"1.0","type":"link"}
