Driven by powerful, integrated Class AB amplifiers with 180 W RMS, the heavy-duty drivers with their rock-solid aluminum cones and heat-resistant voice coils easily transform the amplifier power into punchy bass.\u003c\/p\u003e \u003cp\u003eThanks to comprehensive setting options like the adjustable, high-slope lowpass filter and particularly sensitive phase control, the low-frequency reproduction can be perfectly adapted to the acoustic conditions inside the vehicle. Equipped with a 2-channel high-level input with an automatic turn-on function as well as a 2-channel low-level RCA input a seamless integration is guaranteed. And thanks to the especially shallow cabinet design the installation will be a no-brainer, especially if space is extremely limited – these small \"bass boosters\" may even fit under the seats, for example.\u003c\/p\u003e \u003ch3\u003eProduct Features\u003c\/h3\u003e \u003cul\u003e \u003cli\u003ePowerful, integrated Class AB amplifier with 180 W RMS power for punchy bass\u003c\/li\u003e \u003cli\u003eSolid and low-resonance diecast aluminium housing for precise bass reproduction and optimum heat dissipation\u003c\/li\u003e \u003cli\u003eHeavy-duty 10” \/ 250 mm chassis with extremely stable aluminum cone for compression-free transformation of the amplifier power into sound pressure\u003c\/li\u003e \u003cli\u003e2-channel highlevel input with Auto Turn-on function as well as 2-channel lowlevel input\u003c\/li\u003e \u003cli\u003eContinuously adjustable, steep-flanked lowpass filter\u003c\/li\u003e \u003cli\u003eParticularly sensitive adjustment of the phase\u003c\/li\u003e \u003cli\u003eCable remote control for volume adjustment included in delivery\u003c\/li\u003e \u003cli\u003eEspecially flat housing design - ideal for space-saving under-seat mounting\u003c\/li\u003e \u003c\/ul\u003e \u003cdiv id=\"technicaldata\" class=\"product--technicaldata-headline\"\u003e \u003ch3\u003eTechnical data\u003c\/h3\u003e \u003cdiv id=\"technicaldata\" class=\"product--technicaldata-headline\"\u003e \u003ch3\u003eTechnical data\u003c\/h3\u003e \u003c\/div\u003e \u003cdiv class=\"detail--technicaldata\"\u003e \u003ctable border=\"0\" cellspacing=\"0\" cellpadding=\"0\"\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003e\u003cstrong\u003ePower RMS \/ max.\u003c\/strong\u003e\u003c\/td\u003e \u003ctd valign=\"top\"\u003e180 \/ 360 Watts\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003e\u003cstrong\u003eWoofer diameter\u003c\/strong\u003e\u003c\/td\u003e \u003ctd valign=\"top\"\u003e10\" \/ 250 mm\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003e\u003cstrong\u003eInputs\u003c\/strong\u003e\u003c\/td\u003e \u003ctd valign=\"top\"\u003e2 x RCA \/ Cinch\u003cbr\u003e2 x Highlevel speaker input\u003cbr\u003e1 x Remote In\u003cbr\u003e1 x Remote control input\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003e\u003cstrong\u003eInput sensitivity\u003c\/strong\u003e\u003c\/td\u003e \u003ctd valign=\"top\"\u003eHighlevel 1.2 - 20 Volts\u003cbr\u003eRCA \/ Cinch 0.3 - 4 Volts\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003e\u003cstrong\u003eInput impedance RCA \/ Cinch\u003c\/strong\u003e\u003c\/td\u003e \u003ctd valign=\"top\"\u003e10 kOhms\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003e\u003cstrong\u003eInput impedance highlevel\u003c\/strong\u003e\u003c\/td\u003e \u003ctd valign=\"top\"\u003e33 Ohms\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003e\u003cstrong\u003eFrequency response\u003c\/strong\u003e\u003c\/td\u003e \u003ctd valign=\"top\"\u003e40 - 150 Hz\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003e\u003cstrong\u003eLowpass\u003c\/strong\u003e\u003c\/td\u003e \u003ctd valign=\"top\"\u003e50 - 150 Hz adjustable\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003e\u003cstrong\u003eSubsonic\u003c\/strong\u003e\u003c\/td\u003e \u003ctd valign=\"top\"\u003e16 Hz \/ 12dB\/Oct.\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003e\u003cstrong\u003ePhase switch\u003c\/strong\u003e\u003c\/td\u003e \u003ctd valign=\"top\"\u003e0° \/ 180° switchable\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003e\u003cstrong\u003ePhase shift\u003c\/strong\u003e\u003c\/td\u003e \u003ctd valign=\"top\"\u003e0 - 180° adjustable\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003e\u003cstrong\u003eSlope lowpass\u003c\/strong\u003e\u003c\/td\u003e \u003ctd valign=\"top\"\u003e24 dB\/Oct.\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003e\u003cstrong\u003eSignal-to-noise ratio\u003c\/strong\u003e\u003c\/td\u003e \u003ctd valign=\"top\"\u003e\u0026gt;
