That makes them more versatile in terms of installation as well as performance. \u003cstrong\u003eImproved Circuit Design\u003c\/strong\u003e To prevent circuit shutdown, Pioneer’s new digital amplifier circuit “Protection Control System” senses its internal temperature and automatically moderates input level accordingly. Stable, durable circuitry lessens the risk of high input power for the unit to achieve 1 Ω connection. This design enhances the flexibility to connect multiple subwoofers to a system. \u003cstrong\u003eVariable Low Pass \u0026amp; High Pass Filter\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFor extra flexibility, variable LPF and HPF make audio frequency more adjustable according to subwoofer characteristics and personal listening preferences.

Well, we won’t hold it against you. In fact we’ll even help you build onto your system. Speaker level inputs allow you to connect your OEM unit (or any unit that doesn’t have the typical RCA-type inputs) without having to buy add-on adapters. So, the install goes faster, you save money, and you’ve got a Pioneer amp in your vehicle. \u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e“Hi-Res” Certified Amplifier\u003c\/li\u003e\n\u003cli\u003eCompact Design for Versatile Installation Options\u003c\/li\u003e\n\u003cli\u003ePerfect match for Pioneer TS-Z Series “Hi-Res” Certified Speakers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGeneral\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRCA Inputs: 4-CH (Gold Plated)\u003c\/li\u003e\n\u003cli\u003eAmplifier Class: CLASS-D\u003c\/li\u003e\n\u003cli\u003eHi-Res Certified: Yes\u003c\/li\u003e\n\u003cli\u003eBridgeable: Yes\u003c\/li\u003e\n\u003cli\u003eWarranty: 1 Year\u003c\/li\u003e\n\u003cli\u003eSpeaker Level Input: Yes\u003c\/li\u003e\n\u003cli\u003eFuse Rating: 30A x 2\u003c\/li\u003e\n\u003cli\u003eBass Boost Remote: Yes\u003c\/li\u003e\n\u003cli\u003eAutomatic Signal Sensing and Turn-On: Yes\u003c\/li\u003e\n\u003cli\u003eHi-Volt Input Level Control: 200 mV to 6.5 V\u003c\/li\u003e\n\u003cli\u003eTerminal Type: Block\u003c\/li\u003e\n\u003cli\u003eLoad Impedance Allowance (Ohms): 1 to 8\u003c\/li\u003e\n\u003cli\u003eProtection Control System: Yes\u003c\/li\u003e\n\u003cli\u003eDimensions: 252mm (W) x 60mm (H) x 215mm (D)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003ePower\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eContinuous Power (RMS) Output @ 1Ω: 125W RMS x 4\u003c\/li\u003e\n\u003cli\u003eContinuous Power (RMS) Output @ 2Ω: 150W RMS x 4\u003c\/li\u003e\n\u003cli\u003eContinuous Power (RMS) Output @ 4Ω: 100W RMS x 4\u003c\/li\u003e\n\u003cli\u003eContinuous Power (RMS) Output - Bridged @ 4Ω: 300W RMS x 2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eAudio Adjustments\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLow-Pass Crossover Frequency: 40 Hz\u003c\/li\u003e\n\u003cli\u003eLow-Pass Slope (dB\/octave): -12dB\u003c\/li\u003e\n\u003cli\u003eHigh-Pass Crossover Frequency: 500 Hz\u003c\/li\u003e\n\u003cli\u003eBass Boost Frequency: 50 Hz\u003c\/li\u003e\n\u003cli\u003eBass Boost Level: 0 dB to 18 dB\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eAudio Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFrequency Response: 10 Hz - 50 kHz\u003c\/li\u003e\n\u003cli\u003eTotal Harmonic Distortion (THD): \u0026lt; 0.5% (100 Hz)\u003c\/li\u003e\n\u003cli\u003eSignal-to-Noise (SN) Ratio: \u0026gt; 95dB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PIONEER","offers":[{"title":"Frankies Auto Electrics","offer_id":50837863399697,"sku":"10005709","price":405.21,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0901\/6285\/6209\/files\/61e9534493e2483fbda4491abb297673.jpg?v=1734969715","url":"https:\/\/abcd3032.myshopify.com\/zh\/products\/pioneer-gm-dx874-class-d-4-channel-bridgeable-amplifier","provider":"Tayyab Zak","version":"1.0","type":"link"}
