Connecting speaker leads to both right outputs, A&B, will only play the right channel of the sound (in mono) when both pairs of speakers, A and B are turned on. This won't damage the amplifier or speakers, but you won't be listening in stereo.

How do you use an amplifier?
Amplifiers comes in IC packages diagram is triangle with +/- input by adding a resistor r1 in series to the - input the gain can be found by adding a resistor from output to the - input The + terminal must be satisfied with the proper resistor
How work amplifier?
amplifier consists of active components like transistor fet etc,. for example transistor, it produces high output is common emitter configuration. when u give weak signal to the base of the transistor and the output is taken in collector terminal(amplitude of the weak is increased, so the output is high ) its known as amplifier
When using two 8 ohm speakers with a terminal of 8 ohm should you use parallel or series wiring?
They should be in parallel so that both speakers will (a) get the full damping effect of the low amplifier output resistance, and (b) receive the maximum available voltage swing from the amplifier before limiting and distortion occur. If they sound the same in series, that cancels the effect of 40 years of 'techno' articles on speakers in glossy audio magazines :).
How do you hook up in-ceiling speakers?
If you have standard ceiling speakers (with no transformer), you hook up the speaker wiring, Black to the left terminal, and Red to the right terminal. If you have 70V commercial ceiling speakers (with a transformer), you bypass the transformer by either just using the Black and Red wires off of the transformer, or bypass the transformer by hooking the Black wire to the left terminal, and the Red wire to the right terminal. If you have a 70V commercial speaker system (uses transformers on speakers and a 70V PA amplifier), strip the ends of the appropriate wires you are going to hook up to your 70V system. Do not strip the ends of the other wires you aren't going to be using. Hope this helps! Thanks!
What is the use of operational amplifiers in circuits?
An operational amplifier is typically used where it is desirable to control a voltage over a wide range of levels; i.e., in analog mode as opposed to the on-off limits of a digital signal. An operational amplifier in simplest form will have a non-inverting and an inverting input terminal and an output terminal, each of which are analog in function. The output terminal will tie into external circuit components that eventually connect back to the inverting terminal. The key to its performance is that when a change is made to the voltage on the non-inverting input terminal, the output of the amplifier will change in voltage level, whether increasing or decreasing, to the level that causes the voltage appearing at the inverting terminal to equal that of the non-inverting terminal. In that way the output voltage is a predictible value that is useful for automatically controlling a flow valve or other device. Of course, it can also be used to just to act as a signal conditioner for sensors, audio devices and countless other applications.
What does rem mean on an amplifier?
On an amplifier, rem. usually stands for remote. For an automotive audio amplifier, the remote connection could be for a gain remote. This is usually a dial at one end and a phone jack like connection on the other. This allows you to turn down the gain or volume on the amplifier wherever you wish to mount the remote. If there is a terminal (screw and clamp for attaching wires) under the rem label, then it is for remote shut off. The remote shut off for external amps for like subs or higher end speakers connects a thin blue wire from the head unit or radio to the amplifier. For head units or radios, the remote connection connects to the ignition system. Both of these allow the amplifier to shut off while the key or radio is in the off status. For home theater amplifiers the remote connection could be for a few things. It could be for an IR or Infrared receiver, or to be controlled from another device. These two usually is a 3.5 millimeter female jack terminal. If it looks like a 2 prong 110V receptacle, it will cut the power to another device when the amplifier shuts off.
What does sub vcc means in car amplifier?
It is the power supply terminal.
Where is the ground on an operational amplifier?
An opamp has a ground terminal on one of the pins.
How to Install a Car Amplifier?
Adding an amplifier is a great way improve the sound quality of your system. It can add enhanced detail and realism as well as volume and impact. The transformation of sound is unmistakable and will make driving much more enjoyable. Before installation, determine a good place to locate your amplifier. Good places are usually under a seat, in a trunk, or cargo area. Amplifiers have a tendency to get warm and will need a location that has enough space and ventilation. Since most amplifiers systems do not come with wires, you will need to purchase an amplifier wiring kit. Since the wires you install will be connected directly to the battery, disconnect the negative battery terminal to prevent electrical damage. Run the main power cable from the battery to the amplifier location. Connect this wire to the positive battery terminal. Be sure to remove the fuse located on the power wire before installation. Route the entire power cable through the firewall, through the door, and under the carpet to your amplifier. You may need to remove the back seat when routing the wire into the trunk. Next install the signal cables from the receiver to the amplifier. Run the signal cable on the opposite side of the power cable. Connect the amplifier turn-on lead to the stereo and install it along with the signal cable. Connect both cables to the amplifier. You will need to install a ground lead to the amplifier. This wire should be short and connect directly to a metal component of the car. This could be the chassis or frame of the vehicle. Your final connection will be from the amplifier to the speakers. Use good quality wiring for your speakers. Different quality speaker wires will have a noticeable difference in the quality of the sound. 12 gauge wire is the recommended size for cars. If you need to make longer runs in bigger vehicles then use 16 gauge wire. When all your connections are complete, you are ready to install the fuse located near the battery and reconnect the negative battery terminal. Be sure to reference your owner’s manual for the optimal settings on your amplifier. When routing wire through your car, try to find existing wire connections to pass them through
Where can I get a LAX terminal map?

How do you hook up speaker wire to a speaker?
Each speaker needs to be connected using two wires. One wire is "grounded" and the other carries the alternating sound signal. This question is very simple to ask but is much more complicated to answer because you don't say anything about the kinds of terminals there are on the speaker or the amplifier! On the speaker are there threaded posts with thumb nuts? Or clip-on-wire connectors? Or some other system? On the amplifier what type of speaker output terminals are there: are they screw-down types which need a loop of wire under a washer? Or sockets for phono plugs? Or some other system? There are so many possible wire/terminal combinations it doesn't make sense to write a long essay on all the possible hook-ups you could use. If you cannot work it out from the User Guides that came with the speaker or the amplifier then it is best either to ask a friend who knows about speakers to show you what to do, or ask someone at any store that sells hi-fi systems.
Can I connect two 4 ohm speakers and a 8 ohm speaker?
I depends on "how" you are connecting them. If you connected the 4 ohm speakers in series (positive terminal of one to the negative terminal of the other). This will leave a negative terminal of one unconnected and a positive terminal of the other unconnected. then connect them in parallel (the unconnected positive terminal of the 4 ohm speakers to the positive terminal of the 8 ohm speaker and the unconnected negative terminal of the other 4 ohm speaker to the negative terminal of the 8 ohm speaker. This will produce an overall 4 ohm load for 1 channel (assuming you are connecting to a stereo) Or if you are connecting to a stereo with two 8 ohm outputs. Connect the 8 ohm to one channel then connect the above mentioned series connected 4 ohm speakers to the other channel for a total load of 8 ohms on both channels. Parallel connections will equal less than the individual speaker load. The formula for this is: R X R/R + R where R is ohms for each speaker ie. Two 8 ohm speakers in parallel would be 8 x 8 (64)/ 8 + 8 (16) which is 4 ohms. Series connections you just add them together ie. Two 8 ohm speakers in series would be 8 + 8 or 16 ohms. FYI. If you measure the speakers with an ohmmeter it will be less than what it says on the speakers. Speakers are measured in "impedance" which takes into account "reactance". The resistance of the speaker coil will change slightly with different frequencies applied so an 8 ohm speaker may read as 5-7 ohms (more or less) with an ohmmeter. A 4 ohm may read as low as 2.5 ohms on the same meter. Some output transformers can handle half the ohms but it is always safer, as a general rule, to go "up" in speaker impedance without any damage. It's not wise to vary any with a system with solid state (transistor or IC) output coupling. Hope I didn't get too technical. There is lots of good info on the internet about speaker configurations.
