What is the Amplifier ?
An electronic amplifier, amplifier, or (informally) amp is an electronic device that increases the power of a signal. It does this by taking energy from a power supply and controlling the output to match the input signal shape but with a larger amplitude. In this sense, an amplifier modulates the output of the power supply.
Numerous types of electronic amplifiers are specialized to various applications. An amplifier can refer to anything from an electrical circuit that uses a single active component, to a complete system such as a packaged audio hi-fi amplifier.

How to connect a amplifier in car *STEP BY STEP*
1) Mount your amplifier on a solid surface that will not conduct electricity. In other words, do not mount it on a metal surface.
2Disconnect the negative battery terminal. Make sure you know how to reactivate your radio before doing this, if your radio has a security system.
3Pass the power wire through the firewall. You can put it through an empty rubber grommet in a factory hole.
If there is no available hole, use a power drill and steel bits to drill one. Start with a pilot hole and then work your way up to a size that will fit your wire. Paint the hole's edges to protect against rust.
4Put a rubber grommet in the hole to keep the wire from chaffing.
5Run the power wire to the battery. Start from the interior of the car, and make sure the wire won't get pinched or caught on anything. Run the wire under the carpet by removing the rocker panel and kick panel covers.
6Install an inline fuse holder for the power line 18 inches (46 cm) or fewer from the battery terminal connection. It is best to install it as close as possible to the connection.
Consult the owner's manual or the manufacturer of your amplifier to determine the size fuse you should use.
7Connect the power wire to the amplifier.
8Secure the wire with plastic wire ties.
9Run your RCA cables and remote turn-on lead from the back of the head unit to the amp. Snake them through the car in the same way you did the power wire, but do it on the opposite side of the vehicle. This will prevent noise in the system.
10Connect the speaker wires from the amplifier to the speakers. Situate these wires away from the power wires.
11Connect the amp's negative terminal to the car's chassis ground. Use a short negative power wire that is the same diameter as the positive wire that leads to the battery.
12Insert the main power wire fuse once all the connections for the other wires are in place.
13Connect the negative battery terminal.
14Set all of the input level gain controls to their lowest setting.
15Set bass, treble and loudness levels to 0.
16Set equalizers to their center, or neutral, position if you have them.
17Put in a CD with music that you are familiar with. Choose something strong and clean sounding.
18Turn up the deck's volume until you hear distortion, and set it just below that level. If you don't hear distortion even at the loudest setting, the head unit is in good shape.
19Repeat this process for the input gain, and then with all the other components.
20Play more music and adjust the settings as you prefer.

How to Bridge an Amplifier
Bridging an amplifier allows you to cut the number of channels the amp uses in half and double the power sent to each speaker. It is commonly used in car stereo systems, allowing a powerful mono signal to be sent to a subwoofer. Here are instructions on how to bridge your amp safely.
1-1) Make sure your amp can be bridged. This should be indicated on the documentation that came with the amp. If the amp is used or lacks documentation, go online and check for the specifications on the manufacturer's website

.
1-2) Understand that bridging your amp will cut your channels down by half. A two-channel amp can be bridged to one channel and a four-channel amp, to two channels
Bridge a Two-Channel Amp
2-1) Know the layout of your equipment. On your two-channel amp, you should see 4 terminals: a positive (+) and a negative (-) for channel 1 and the same for channel 2. Let's label each terminal as follows:
Chanel 1 : A (positive) B (negative)
Chanel 2 : C(positive) D(negative)
2-2 ) Connect the amp to one speaker.
Connect the red (or ribbed) speaker wire to terminal "A.”
Connect the black (or non-ribbed) speaker wire to terminal "D."
Bridge a Four-Channel Amp
3-1)Know the layout of your equipment. On your four-channel amp, you should see 8 terminals: channels 1 through 4 each have a positive (+) and negative (-) terminal. Let's label each terminal as follows:
Channel 1
“A” (positive)
“B” (negative)
Channel 2
“C” (positive)
“D” (negative)
Channel 3
“E” (positive)
“F” (negative)
Channel 4
“G” (positive)
“H” (negative)
3-2) Connect the amp to the first speaker.
Connect the red (or ribbed) speaker wire to terminal "A.”
Connect the black (or non-ribbed) speaker wire to terminal "D."
3-3) Connect the amp to the second speaker.
Connect the red (or ribbed) speaker wire to terminal "E.”
Connect the black (or non-ribbed) speaker wire to terminal "H."

How To Connect Tweeters To Car Audio Speakers In a Car + crossovers
If you have a pair of tweeters that you want to install into your car to gain more treble in the music you listen to and don't have an active crossover box, then you can still connect the tweeters to the car speakers in your vehicle, by creating a passive crossover system. A active crossover is the best option for car audio, when installing tweeters because it separates the mid and the high frequencies and only sends the correct frequencies to the appropriate drivers, so you will gain more sound quality along with better sounding clarity. But if you don't have this type of crossover and want to connect them to your car speakers, then you have to protect the tweeter, this is by soldering a small electrical capacitor to the positive terminal, inline with the speaker wire. The capacitor acts as an high pass filter and is there to protect the tweeter's voice coil getting damaged, as the bass frequencies get filtered out.
1) First of all you need to connect speaker wires to both tweeters, this is so you can connect them to each car speaker. So using a pair of 12 or 14 gauge speaker wires, a soldering iron and some solder wire, connect the striped wire to the positive (+) terminal on the tweeter, then the plain black wire to the negative (-) terminal and solder them on, to make the connections secure, to prevent cracking occurring late on. Repeat this step for the other tweeter.
2) Now that you have connected the speaker wires to the tweeters, you are now ready to connect them to your car speakers in your vehicle. So remove the car speaker from its mounted location, this is by removing the front protective grill and then getting an screwdriver and unscrewing all the screws.
3) Then remove the car speaker from the hole and turn it upside, so you can access the terminal connections. Strip the insulation off the wires, if they don't have braid on the ends. Then connect the striped wire to the positiver terminal on the speaker, it will be marked as an (+) symbol. Then connect the plain black wire to the negative terminal on the speaker, it will be marked as an (-) symbol. Repeat this step for the other speaker and tweeter. Once you have made the connections, then test if the tweeters are working, this is by powering on your head unit and playing an random track.

How to Connect a Subwoofer to an Amplifier
Audiophiles know that a stereo is not complete until you've added a subwoofer to your system. The subwoofer is a speaker specifically designed to give precise sound to low frequency audio, such as the bass . Whether in your car or your home theatre, a subwoofer is a must for a true and complete audio experience. Read the steps listed below and learn about how to connect a subwoofer to anamplifier.
- Turn the amplifier and the subwoofer so the backs are facing you. You will be able to clearly and accurately see the labels on top of the outputs and plugs.
- Locate the plug on your amplifier that is labeled Sub Out, LFE (low frequency effects) Out or Line Out.This is the terminal used to connect the subwoofer to the amplifier.
- Connect the cable that was included with the subwoofer to the amplifier's terminal. Alternatively, you can connect an RCA cable that can be purchased at any electronics store.
- Connect the other end of the cable to the terminal on the back of the subwoofer marked Line In.
- Insert an audio disc that has deep bass sounds and press play. Human ears are the best devices for gauging whether your subwoofer is set up properly. Set the phase control on the amplifier to zero and the output to minimum. Throughout the song, adjust the levels until you're satisfied with the amount of bass coming out of your subwoofer.
