Post from: Pro Audio Microphones
u can put a switch on the lil blue remote wire do not put it on the power wire
There are many sites that list schematics for high power amps (check google), and can be modified for more power. But it will be cheaper to buy one already made than to buy all the components and build it yourself.
If that was the advertisement, then their ad is misleading. Even if they were advertising max watts, the total would still only be 75 watts x 2 = 150 watts RMS. Max would be 150 watts x 2 = 300 watts. Perhaps the 75 watts is into 8 Ohms? However, even if it is and the amplifier can double its power into 4 Ohms (most amps on the market will not fully double in ooutput power by cutting the impedance in half) the total watts would still max out at only 600 watts.What model of amplifier is it? Since there are so many other variables that will determine the amplifier’s worth, if you can tell me what brand and model of amp it is, I can help you with what it’s worth.H a p p yH o m eT h e a t e r i n g !Xe♫
try to find your product here http://www.memphiscaraudio.com/ or you can put your model number in the search field on the Internet and go to different sites that sell it and look up the specs there
By ‘testing’ the audio amplifier, we want to find out how well it amplifies different input frequencies. A square wave can be made by adding together many different harmonics of sine waves.http://www.bores.com/courses/intro/freq/3_ft.htmThus, by passing a square wave into the input of the amplifier and measuring the output on an oscilloscope, you can see how linear the amplifier is by the shape of the output signal.Loss of low frequencies will cause the output square wave to have rounded edges. Loss of high frequencies will show up as ripples on the square wave output.Cheers,A.
(m)An audio amplifier is an electronic amplifier that works with audio frequencies (generally 20 hertz to 20,000 hertz).OverviewAn audio power amplifier is the final stage in the audio playback chain and its purpose is to amplify the electrical audio signal from its preceding stage to a level that can drive the loudspeaker(s). The preceding stages are low power audio amplifiers which perform tasks like pre-amplification, equalisation, tone control, mixing/effects, etc or audio sources like record players, CD players, cassette players, etc. By “low power” it is meant that the signals are usually limited to those required to drive headphones (less than 500 mW).While the input signal may be only a few hundred millivolts, the power amplifier’s output may have a power of many watts.Early audio amplifiers were based on vacuum tubes (also known as “valves”). Most modern audio amplifiers are based on solid state devices like transistors, FETs and MOSFETs, but there are still aficionados who prefer tube based amplifiers, as they have a ‘warmer’ sound. Audio amplifiers based on transistors became practical with the appearance of cheap transistors in the late 1960’s.ApplicationsImportant applications include public address systems, home and car sound systems. The sound card in a personal computer contains several audio amplifiers (depending on number of channels), as does every stereo or home-theatre system.Design parametersKey design parameters for audio amplifiers are frequency response, gain, noise, and distortion. These are interdependent, increasing gain often leads to undesirable increases in noise and distortion. While negative feedback actually reduces the gain, it also reduces noise, oscillation and distortion.[
basically, they are the same.
Use a volt meter to see where the power stops
It may be the RCA cords themselves.
Running the main power off the battery is the best way. The only time you should install a second battery for your system is when you are planning on running multiple amps and subs the would require more power, then your car battery wont have enough power that your system needs. Before thinking about adding another battery a power capacitor will help a system with the power need to run the everything efficiently.
