Aftermarket Underseat Subwoofer for 1 series/ 1M? Post Reply Thread Tools: Search this Thread 07-03-2011, 06:18 PM … Underseat subwoofer spec? Bimmerpost ☰ Model Selection G20Model Year: 2019 + Previous Generations F30 / F31Model Year: 2012 - 2018. In layman terms the outputs from the Harman Kardon cannot be plugged directly into an after market amp as there is too much power. to/2A2iTeQ Makita Impact: … Audison connect RCA cable 2. This means that the amplifier and the very fast digital switching remains un-hearable in the audio bandwidth for music.Bmw f30 underseat subwoofer. In addition, circuit engineers can design better circuits for power and sound quality as the tolerances of SMT components are superior to larger "through-hole" components.īecause of their lower mass SMT components withstand shock and vibration making them perfect for audio designed for all vehicles.ģ00KHZ HIGH SPEED PULSING: The switching speed of the Class D chip puts the amplifier sampling frequencies at over 100 times higher than human ears can hear. With Surface Mount Technology the typical "through-hole" placement and the larger tolerances from human placement is dramatically improved. With this focus on engineering, ALPHA delivers big sound while remaining very musical in a compact chassis is the result. Only a few holder head units will not use this function.įull Range Super D-Class® circuitry delivers high efficiency/high power technology to deliver maximum wattage. ![]() The AUTO TURN-ON function will work with 90% of all source units because they are equipped with "high power" output. Using this feature eliminates the need to use the REM (turn on wire). ![]() When the source unit is turn off the amplifier is also turned off. Thus, the amplifier will also be turned on. The amplifier detects a voltage rise (6 volts) with a "DC Offset" over the connected input signal on the HIGH LEVEL INPUTS when the head unit or source unit is switched on. Monitor overload and speaker short protection with illuminated indicators on the amplifier end panel. LED System Protection Circuitry Diagnostics Angled for ease of access during installation. Secure connection for all power, ground and speaker connections. Nickel-plated, high temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant. The Twin Turbo Coil PS is a Pulse Width Modulated power supply keeps voltage constant through the Ultra-Fi output devices. Heavy duty aluminum alloy heat-sink efficiently moves heat from the MOSFET where it can be cooled. It produces very musical high power with high efficiency for cooling and minimal distortion. The Ultra-Fi™ MOSFET is designed for music production vs just electronics output power. Check specifications for specific frequencies for this amplifier.ĭeveloped over 4 decades of engineering to deliver the highest level of sound quality and power efficiency, Hifonics ALPHA Full Range Super D-Class® circuitry results in lower distortion, higher current efficiencies and while producing less heat than conventional amplifier designs. See specifications section for specific frequencies.Ĭontrol of amplifier output with on board electronic crossover to tailor specific frequencies to speakers and subwoofers. Nickel plated RCA connectors for audiophile signal quality and maximum signal throughput with minimum distortion and maximum external noise rejection.įlexible installation allows this amplifier to run in either two channel or bridged mono mode.Īccu-Cross crossovers allow for complete control of the signal directing to all speakers. Maximum low voltage signal from the source unit comes into the amplifier through a low voltage circuit which delivers minimal distortion through the amplification process. WARNING: Cancer and Reproductive Harm - Low Noise Preamplifier Circuit ![]() TURN ON CIRCUIT: Switched - Remote Turn-On / Signal Sense On, HEATSINK SIZE: Length 16.0in x Depth 9.25in x Height 2.37in Amp Variable High Pass Crossover 12dB per OctaveĪmp Variable Low Pass Crossover 12dB per Octave
