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.

Circuit Description 1000W Power Amplifier:
Power amplifier has up to 1000 Watt power, this circuit made one channel only so if you want to create a stereo in it must be made one again, actually this is more suitable power amplifier in use for Sound System or outdoor, so if only in use for the house I think is less suitable.
Maybe you've seen or even have an active speaker and there is written 1500 watts PMPO (Peak Music Power Output), make no mistake this is different from Power Amplifier Active Speaker, I often dismantle such Active Speaker in it only a power with power no more than 150 watts by using the transformer 2-3 Ampere. PMPO is not a real power which is issued by the Power Amplifier, but counting all the speakers that there is, for example: if there are 5 pieces of speakers on each channel and each speaker has a power of 10 W then it is 100 W PMPO.

Partlist 1000W Power Amplifier:
While this 1000 Watt Power Amplifier minimal use transformer 20 Ampere. And the output of PowerAmplifier DC voltage contains approximately 63 volts, with currents and voltages of this magnitude, this 1000 Watt Power Amplifier will not hesitate hesitate to destroy your woofer speakers to connect. To overcome that then before the speaker on connects to 1000 Watt Power Amplifier must be in pairsSpeaker Protector.
Actually if you want to create a Power Amplifier with great power does not have to make a PowerAmplifier with great power. Example: you want to create a Power Amplifier with 10 000 Watt power. You do not have to assemble a Power Amplifier with power of 10,000 watts, but you assemble thepower Power Amplifier Small but many, such as you assemble the Power Amplifier with 1000 Watts of power for as many as 10 pieces, it will produce 10 000 Watt Power Amplifier helpless.
Circuit uses power transistors pair of 5 x 5 x 2SA1216 and 2SC2922 and 2SC1583 use a differentialamplifier that actually contains 2 pieces of transistors that are in containers together. Why use such built-in amplifier differental tujuanya so identical / similar, could have uses 2 separate transistors but can result in amplifier so it is not symmetrical.
Tips combining speaker.
To get the speakers with great power combining techniques can be used in parallel series, combining each group of speakers should sepaker they will have the same impedance, the same type (Woofer, Mid Range or tweeter) and the same power. Number of merging these speakers should consists of 4 , 9, 16 ff, see picture
Example: The number of speakers have 4 pieces each of its 200 Watt power generated will be aspeaker at = 200 x 4 = 800 Watt. If there are 9 speakers 200 W then the result = 9 x 200 W = 1800Watt.
Circuit Description
IC TA8210AH By using this you can apply a series of audio power amplifier is the car audio system. In general, all the speakers in the car using a subwoofer speaker, and woofer. Because the car is not big room so the sound is being required is not too high. Audio amplifier circuit can work at a minimum voltage 12-volt DC, if supplied under voltage 12-voltamplifier work will be less than the maximum. This amplifier output power up to 200W or 2 x 100W stereo with 8 ohm impedance.

It may seem a little excessive, but since I had the programmer, the C compiler and some spare PIC16F627 chips, this solution to handling power on mute, 12V trigger powering and LED for status would be small, reliable and cheap.
Three relays would be involved.
Mains switching relay, to switch in the 225VA toriodal transformer
Output switching relay, to disconnect the speaker from the amp
Input switching relay, to remove any input so the output switching relay switches a very small current, prolonging its life (thanks to Mark Hennessy for this idea).
Two LEDs would be on the front of the box. One LED for standby, one (blue) LED for power on. The would both flash in turn when the power on sequence runs.
Finally, there would be two inputs. One small push button for mounting on the front of the case for manual power on/off, and one 12V trigger input, isolated using a standard opto-isolator in order to prevent earth loops.
Thats all there is to it. Without the PCB mount transformer, the PCB turns out pretty small. It has been desgined to fit my relays (and other components) I had available to me, but is provided as a scan below if you want to use (and modify it in your subwoofer/power amplifier project. The C file, and HEX file for the PIC micro is also provided.

The output power: 40 w 8 ohm and 60 w 4 ohm load. Preamplifier is used in the same 60 v rails as the power amplifier gain blocks can implement two transistors can provide about 20 v RMS output. This provides a very high input overload. List at least the recommended value is C8. 3300μf capacitor or two 2200μf capacitors connected in parallel would be a better choice. Darlington transistor types of alternative has MJ11014 (Q3) and MJ11013 (Q4) or TIP142 (Q3) and TIP147 (Q4). T1 transformer can be also a 24 24 v or 25 25 v type (ie. 48 v or 50 v center tapped). SW1 switch insert low-cut feature when open. In all cases, Darlington transistors are used as the output device is essential that the transistor (Q2) pass in close thermal contact with the sensor output transistors as possible.
