One amp, one power run, one ground — full system power for front stage, rear fill, and sub. Bridge the front channels to 140W RMS x2 for a high-powered front stage alongside the 500W sub channel, and you have a 3-channel configuration that rivals dedicated multi-amp setups.\u003c\/p\u003e\n\n\u003cp\u003eThe Club A5055 is built around JBL's Club Series amplifier platform, delivering clean, efficient power across all five channels simultaneously. The four full-range channels handle 50W RMS x4 at 4 ohms or 65W RMS x4 at 2 ohms — enough to drive JBL Club Series component speakers to their rated power. The dedicated subwoofer channel puts out 320W RMS at 4 ohms or \u003cstrong\u003e500W RMS at 2 ohms\u003c\/strong\u003e, with a \u003cstrong\u003e0–12dB bass boost at 45Hz\u003c\/strong\u003e and a \u003cstrong\u003e0\/180-degree phase switch\u003c\/strong\u003e for precise sub integration.

Both preamp (RCA) and \u003cstrong\u003espeaker-level inputs\u003c\/strong\u003e are supported for seamless integration with factory head units or aftermarket sources. An included \u003cstrong\u003eremote bass knob\u003c\/strong\u003e keeps subwoofer level control at your fingertips. Fuse rating is 30A x3 (90A total); recommended wiring is 4-gauge power and ground.\u003c\/p\u003e\n\n\u003cp\u003eThe Club A5055 is the ideal single-amp solution for a complete JBL Club Series system — pair with Club 64C or Club 64CSQ component speakers up front, Club 64 coaxials in the rear, and a JBL Club Series subwoofer for a fully matched, high-output system.

For a full JBL Club Series system: run channels 1+2 to front Club 64C or 64CSQ components (high-pass at 80Hz), channels 3+4 to rear Club 64 coaxials (high-pass at 80Hz), and the sub channel to a JBL Club Series subwoofer (low-pass at 80Hz). Set the sub channel bass boost to taste — start at 0dB and increase only if needed. For a 3-channel high-powered front stage, bridge channels 1+2 to 140W RMS and 3+4 to 140W RMS, and run the sub channel at 500W RMS into a 2-ohm load. A DSP processor between the head unit and amp will add time alignment and active crossover control for a significant performance upgrade.\u003c\/p\u003e\n\n\u003ch2\u003eFull Specifications\u003c\/h2\u003e\n\u003cdiv style=\"overflow-x:auto;\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eJBL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eClub A5055\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannels\u003c\/td\u003e\n\u003ctd\u003e5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Output (4Ω, Full Range)\u003c\/td\u003e\n\u003ctd\u003e50W RMS x4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Output (2Ω, Full Range)\u003c\/td\u003e\n\u003ctd\u003e65W RMS x4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBridged Power (4Ω)\u003c\/td\u003e\n\u003ctd\u003e140W RMS x2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSub Channel Power (4Ω)\u003c\/td\u003e\n\u003ctd\u003e320W RMS x1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSub Channel Power (2Ω)\u003c\/td\u003e\n\u003ctd\u003e500W RMS x1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFront\/Rear Crossover\u003c\/td\u003e\n\u003ctd\u003eHP\/LP Variable, 32–320Hz, 12dB\/oct\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSub Crossover\u003c\/td\u003e\n\u003ctd\u003eLP Variable, 32–320Hz, 12dB\/oct\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBass Boost\u003c\/td\u003e\n\u003ctd\u003e0–12dB @ 45Hz (Sub Channel)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhase Switch\u003c\/td\u003e\n\u003ctd\u003e0° \/ 180° (Sub Channel)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInputs\u003c\/td\u003e\n\u003ctd\u003ePreamp (RCA) \u0026amp; Speaker-Level\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFuse Rating\u003c\/td\u003e\n\u003ctd\u003e30A x3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Wiring\u003c\/td\u003e\n\u003ctd\u003e4-Gauge Power \u0026amp; Ground\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (W x H x D)\u003c\/td\u003e\n\u003ctd\u003e36cm x 5.1cm x 18cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e4.2 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I use the Club A5055 with my factory head unit?\u003c\/strong\u003e\u003cbr\u003eA: Yes — the speaker-level inputs connect directly to your factory head unit's speaker outputs without a line output converter. This makes it one of the easiest 5-channel amplifiers to integrate into an OEM system.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I bridge the Club A5055 for more front stage power?\u003c\/strong\u003e\u003cbr\u003eA: Yes — bridge channels 1+2 for 140W RMS at 4 ohms and channels 3+4 for 140W RMS at 4 ohms, while the sub channel runs independently at up to 500W RMS at 2 ohms. This 3-channel configuration delivers a high-powered front stage alongside serious sub output.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What subwoofer pairs best with the Club A5055?\u003c\/strong\u003e\u003cbr\u003eA: A JBL Club Series subwoofer rated 300–500W RMS is the natural match. Wire a dual voice coil sub to 2 ohms to take full advantage of the 500W RMS sub channel output. Contact us at Trinity Car Audio for a specific subwoofer recommendation based on your enclosure and goals.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Do I need a DSP processor with the Club A5055?\u003c\/strong\u003e\u003cbr\u003eA: Not for basic system integration — the onboard crossovers handle speaker protection and sub integration. However, a DSP processor adds time alignment, active crossover control, and equalization that will significantly improve soundstage imaging and overall system performance, especially with a component front stage.\u003c\/p\u003e","brand":"JBL","offers":[{"title":"Default Title","offer_id":49849840107748,"sku":"AMPCBA5055AM","price":479.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0842\/2522\/9028\/files\/JBL_Club_a5055_1605x1605_hero.png?v=1789257447","url":"https:\/\/www.12voltoutlet.com\/products\/jbl-club-a5055-5-channel-car-amplifier","provider":"12 Volt Outlet","version":"1.0","type":"link"}
