For a full 4-speaker system, run the amp in 4-channel mode with the crossover set to high-pass at 80–100Hz to protect your speakers from low-frequency content. To add a subwoofer, bridge channels 3+4 to drive a mono sub load and use channels 1+2 for the front stage. Pair with JBL Stage3 or Club Series speakers for a matched system. 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\u003eSTAGE GT 60041\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAmplifier Class\u003c\/td\u003e\n\u003ctd\u003eClass-D\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannels\u003c\/td\u003e\n\u003ctd\u003e4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Output (4Ω)\u003c\/td\u003e\n\u003ctd\u003e65W RMS x4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Output (2Ω)\u003c\/td\u003e\n\u003ctd\u003e90W RMS x4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Output (Bridged 4Ω)\u003c\/td\u003e\n\u003ctd\u003e180W RMS x2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePeak Power\u003c\/td\u003e\n\u003ctd\u003e1,240W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency Response\u003c\/td\u003e\n\u003ctd\u003e20Hz – 20kHz (±1dB)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTHD+N @ ROP\u003c\/td\u003e\n\u003ctd\u003e1%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Sensitivity (Low)\u003c\/td\u003e\n\u003ctd\u003e1V – 25V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Sensitivity (High)\u003c\/td\u003e\n\u003ctd\u003e0.2V – 5V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCrossover (Variable)\u003c\/td\u003e\n\u003ctd\u003e32Hz – 320Hz (HP\/LP)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBass EQ\u003c\/td\u003e\n\u003ctd\u003e0 – 12dB @ 45Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtection\u003c\/td\u003e\n\u003ctd\u003eDCP, OVP, UVP, OCP, OTP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e9V – 16V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFuse Rating\u003c\/td\u003e\n\u003ctd\u003e20A x2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Weight\u003c\/td\u003e\n\u003ctd\u003e2.2 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 Stage GT 60041 with my factory head unit?\u003c\/strong\u003e\u003cbr\u003eA: Yes — the high-level input (0.2V–5V) connects directly to your factory speaker outputs without a line output converter. This makes it one of the easiest amplifiers to integrate into an OEM system.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I bridge the Stage GT 60041 to run a subwoofer?\u003c\/strong\u003e\u003cbr\u003eA: Yes — bridge channels 3+4 for 180W RMS at 4 ohms to drive a subwoofer, and use channels 1+2 in stereo for the front stage. Set the low-pass crossover on the bridged channels and high-pass on the front channels for a clean system integration.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is the Stage GT 60041 compatible with start-stop vehicles?\u003c\/strong\u003e\u003cbr\u003eA: Yes — the 9V–16V operating voltage range is specifically designed to handle the voltage fluctuations of modern start-stop electrical systems without shutting down or causing noise.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What speakers pair best with the Stage GT 60041?\u003c\/strong\u003e\u003cbr\u003eA: JBL Stage3 and Club Series speakers are the natural match — the 2–4 ohm stable output pairs perfectly with JBL's 3-ohm Club and Stadium Series drivers.

4-channel lineup — built on premium \u003cstrong\u003eKorean Class-D technology\u003c\/strong\u003e and engineered to deliver clean, high-output power across all four channels with the flexibility to adapt to virtually any system configuration. Whether you're running a full front and rear speaker stage, bridging into a 2-channel setup for component midranges, or pushing a compact subwoofer alongside your door speakers, the 800.4 has the output and the versatility to handle it all.\u003c\/p\u003e\n\n\u003cp\u003eThe 800.4 puts down \u003cstrong\u003e220W x 4 @ 2 ohms\u003c\/strong\u003e, \u003cstrong\u003e100W x 4 @ 4 ohms\u003c\/strong\u003e, and a powerful \u003cstrong\u003e440W x 2 bridged @ 4 ohms\u003c\/strong\u003e at 14.4V — real, usable power across every configuration.

Pair it with a quality 4-channel RCA signal from your head unit or DSP processor for best results. A 4-gauge power and ground wiring kit is the minimum recommendation, with a 100-amp fuse inline on the power run as specified by Ruthless Audio. Keep power and ground runs as short as possible, and route RCA cables away from power wiring to eliminate noise.\u003c\/p\u003e\n\u003cp\u003eWhen bridging the 800.4 to 2 channels, verify your speakers or subwoofer can handle the increased output and are rated for a minimum 4-ohm bridged load. Use the onboard clip light to set your gain — back off the gain until the clip light extinguishes at your typical listening volume, then fine-tune from there.
