The speed of the switches must be much higher than the desired frequencies of the input signal.

We designed specific circuitry that reduces distortion further and increasing the sound quality and power.Īmplifier, Class D – In simple terms, a Class D amplifier is an electronic amplifier where the power devices, usually MOSFETs, are operating as binary switches, being either fully on or fully off. The “gain” of an amplifier is the ratio of output to input power or amplitude, and is usually measured in decibels (dB).Īmplifier, Class A/B – Class A/B amplifiers have been long known for their ability to produce great quality (Class A portion) while having efficiency better than pure Class A amplifiers.

Basically the amplifier acts as the power source for the car sound system by modulating the power generated by the car battery to allow the speakers to reach their full potential. When adding aftermarket components, an amplifier is often necessary to provide additional output to the speakers and subwoofers. The “head” unit (such as a radio or CD player) in a car has limited power and typically does not have the power to operate additional or larger speakers. AWG is identical to the Brown and Sharpe (B & S) wire gauge.Īmplifier – Simply put, an amplifier (amp) is a device for increasing the power of a signal. The science of production, effects and transmission of sound waves through various mediums, and the effects of absorption, diffraction, interference, reflection, and refraction.Īlternator – A device that is turned by a motor to produce AC voltage, which is then rectified (turned into DC) and used to supply voltage to the vehicle’s electrical system.Īlternator Whine – A whining that is heard when the RPM of an engine increase – usually the result of a voltage differential created by more than one ground path or a poor ground path (ground loop).Īmerican Wire Gauge (AWG) – A standard of the dimensional characteristics of wire used to conduct electrical current or signals. AĪccessory (position) – Refers to the position of the key in the ignition switch A wire showing 12 Volts (+) when in this position.Īcoustics – The study of sound. Please note this particular amp needs a healthy electrical system that is capable of delivering the current the amp demands. This amp can comfortably power speakers with all channel(s) being used at a 2 ohm load.ġ Ohm Stable – An amplifier that is capable of delivering power at a 1 ohm load is usually reserved for serious subwoofers that can take the power. Wattage starts to get very expensive once you get up that high and the gains are minimal.4 Ohm Stable – The lowest impedance accepted by the amplifier will be 4 Ohm, which won’t be a problem, as most automotive speakers are 4 ohm impedance.Ģ Ohm Stable – Amplifiers capable of powering speakers at lower impedance produce more power. The guys with 10,000 watt systems are just insane and seem to have endlessīank funds. There are 1 watt sound competition classes!!

In order to increase the sound level 3dB, you must double the wattage.Ī set of speakers with a sensitivity of 90dB is usually measured at 1kHz with 1 watt of power from 1 meter away. They will be louder with less wattage-keeping your volume level lower, in turn keeping the noise levels lower. If you don't have much wattage to play with, then get speakers with a high sensitivity rating, say 90dB or higher.

3dB is the smallest change in sound level detectable by the human ear. So, for the stock head unit, I would say it is roughly 160/4 channels =40 watts max per channel/2= 20 watts RMS per channel.ĥ0 watts won't be much louder than than 20 watts. In higher end amps, the true RMS value may be given though. RMS is the 'nominal' or 'continuous' power from an amp and is generally half of the amp's 707 of peak.īut, In the audio world, the term RMS is used a bit more loosely.
