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. Thanks 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 highlevel input with automatic turn on function as well as a 2-channel lowlevel 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\n\u003cp\u003ePowerful, integrated Class AB amplifier with 180 W RMS power for punchy bassSolid and low-resonance diecast aluminium housing for precise bass reproduction and optimum heat dissipation Heavy-duty 8\" \/ 200 mm chassis with extremely stable aluminum cone for compression-free transformation of the amplifier power into sound pressureIntegrated Class AB amplifier with 180 W RMS powerContinuously adjustable, steep-flanked lowpass filterParticularly sensitive adjustment of the phaseCable remote control for volume adjustment included in deliveryEspecially flat housing design - ideal for space-saving under-seat mounting\u003c\/p\u003e\n\u003cp\u003ePower RMS \/ max. 180 \/ 360 WattsWoofer diameter 8\" \/ 200 mmInputs 2 x RCA \/ Cinch2 x Highlevel speaker input1 x Remote In1 x Remote control inputInput sensitivity Highlevel 1.2 - 20 VoltsRCA \/ Cinch 0.3 - 4 VoltsInput impedance RCA \/ Cinch 10 kOhmsInput impedance highlevel 33 OhmsFrequency response 45 - 150 HzLowpass 50 - 150 Hz adjustableSubsonic 16 Hz \/ 12dB\/Oct.Phase switch 0° \/ 180° switchablePhase shift 0 - 180° adjustableSlope lowpass 24 dB\/Oct.Signal-to-noise ratio \u0026gt; 92 dB (A-weighted)Distortion (THD) \u0026lt; 0.4 %Operating voltage 10.5 - 16 VoltsFuse 25 A Maxi-fuse (APX)Additional features Diecast aluminum housing, cable remote control for volume adjustment, Auto Remote switch Dimensions (H x W x D) 78 x 245 x 345 mm \/ 3.07 x 9.65 x 13.58\"\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Helix","offers":[{"title":"Default Title","offer_id":53492459209085,"sku":null,"price":259.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0561\/6998\/8144\/files\/32_2ed713e2-b195-4205-bb81-3e6fb8124b3e.png?v=1727431111","url":"https:\/\/www.bigsoundslowskirts.com\/products\/helix-u-8a-ultra-compact-underseat-20cm-8-active-amplified-subwoofer_163328748864_","provider":"BigsSoundsLowSkirts","version":"1.0","type":"link"}
