Need help knowing how to match a car subwoofer and amplifier? Tired of your friends constantly asking you to pair a sub and amp for them? Watch this video (or send it to a friend) and learn about the three major points of matching subwoofers and amps: The Total RMS of the System The Final Impedance of the System Types of Amplifiers In this video we use the 750 watts RMS Kicker CVX (CompVX) subwoofer and the Kicker ZX750.1 amplifier (750 watts RMS @ 2 ohm) as an example of a perfectly matched subwoofer and amp.

Bandpass Designer Software calculates 4th order bandpass theoretical enclosures and boxes. Download >> Input Parameters: The following Theile Small speaker parameters are required for input. These values should be included with your speaker manual or can be found on the manufacture's web site.  Qts -  Total Q of the speaker Qes - Speaker electrical Q Fs - Free air resonance of speaker in Hz Vas - Volume of air equal to the speakers spring characteristics in liters Pmax - Maximum power of the driver in watts Diameter - The diameter of the driver in cm Xmax - The amount of cone movement in one direction in mm Dp - Diameter of the port(s) in cm Ports - Number of ports The following speaker parameters are user defined inputs. These values should be inputted by user preference.  Gain: dB increase of the system: S: Ripple S = 0.5 - Degraded response pronounced ripple S = 0.6 - Slightly degraded response sl...

General Description: The TDA1015 is a monolithic integrated audio amplifier circuit in a 9-lead single in-line (SIL) plastic package. The device is especially designed for portable radio and recorder applications and delivers up to 4 W in a 4 Ω load impedance. The very low applicable supply voltage of 3,6 V permits 6 V applications.  1 to 4 W audio power amplifier Special features: single in-line (SIL) construction for easy mounting separated preamplifier and power amplifier high output power thermal protection high input impedance low current drain limited noise behaviour at radio frequencies Circuit Diagram: 1 to 4 W audio power amplifier circuit diagram Datasheet for TDA1015:   Download

GENERAL DESCRIPTION: The TDA1013B is an integrated audio amplifier circuit with DC volume control, encapsulated in a 9-lead single in-line (SIL) plastic package. The wide supply voltage range makes this circuit ideal for applications in mains and battery-fed apparatus such as television receivers and record players. The DC volume control stage has a logarithmic control characteristic with a range of more than 80 dB; control is by means of a DC voltage variable between 2 and 6.5 V. The audio amplifier has a well defined open loop gain and a fixed integrated closed loop. This device requires only a few external components and offers stability and performance.  4 W audio power amplifier with DC volume control Features: Few external components Wide supply voltage range Wide control range Pin compatible with TDA1013A Fixed gain High signal-to-noise ratio Thermal protection PINNING: power ground amplifier output supply voltage electronic...

General Description: The LM4910 is an audio power amplifier primarily designed for headphone applications in portable device applications. It is capable of delivering 35mW of continuous average power  to a 32Ω load with less than 1% distortion (THD+N) from a 3.3VDC power supply. The LM4910 utilizes a new circuit topology that eliminates output coupling capacitors and half-supply bypass capaci-tors (patent pending). The LM4910 contains advanced pop & click circuitry which eliminates noises caused by transients that would otherwise occur during turn-on and turn-off. Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. Since the LM4910 does not require any output coupling capacitors, half-supply bypass capaci-tors, or bootstrap capacitors, it is ideally suited for low-power tors, or bootstrap capacitors, it is ideally suited for low-power sumption are primary requirements. ...
