Yes, there are many types and models of amplifiers. Some have built in LINE OUT options and others require work. Active speakers are just speakers with their own built in amplifiers that supply power only to their own speakers or additional Sub Woofer.
With some Guitar AMPS it is necessary to daisy chain (Think Jimmy Hendrix) the input jacks from one amplifier and bridge the guitar signal from one channel to the input of the second amplifier via a jumper cable. Phase (Timing of the speakers) becomes a challenge or in Hendrix case an asset, but it works.
When you have only one channel jack and no Line Out options you can simply MIC the speakers of the first Amp and play the sound through a second (PA) amp.
you need to choose speakers according to the power supply of amplifier, so that the amplifier can wrok. Besides, to create good sound effect, you need to take your room area into consideration, if the room is small, amplifier and speakers with high power is not necessary. You can visit website of Unify company, they have many packages for amplifier and speakers, hope it can help somehow.
It's entirely possible to use four 70W speakers with a 150W amplifier but the method will depend on the speakers and the amplifier specification. We will assume that the amplifier will deliver up to 150W per channel, so two speakers will be used on each channel. If the amplifier is rated to drive a 4 ohm load, then two 8 ohm speakers can be wired in parallel and connected. In this instance, take care NOT to drive the amplifier too hard. It will overdrive the speakers at about the same time that it will begin to show a distorted output. This is a condition that can easily damage speakers so be very conservative with the volume control. If the speakers are 4 ohm speakers, they can be wired in series to provide a total impedance of 8 ohms. If the amplifier is rated to deliver 150W into 4 ohms, then the total power to the speakers will be lower than to a single speaker. The benefit is that no speaker can be over-driven and there is a good amount of headroom for safety.
A: Absolutely
The subwoofer is the actual speaker making the loud bass. The amplifier is what powers the subwoofer and makes it work how it does. It only uses the low frequencies from the audio source and amplifies it.
A1: The output impedance of a power amplifier is always less than 0.1 ohms. There are no 4 ohm amplifiers on the market! A2: I actually just bought a new car radio/CD player that specifically shows 4 ohm speakers on the sticker. It is designed to work optimally with 4 ohm speakers. If you use 8 ohm instead, it will work, but you will not get the full power output that is specified. The amp can only kick out so much voltage and so much amperage - if it is designed for 4 ohm speakers, and 200 watts (stereo, so 100 watts per speaker), it can supply 20 volts (P = V^2 / R). If you used 8 ohm speakers to this amplifier, each speaker would only get 50 watts powered at full output voltage. Alternatively, if it is designed for 8 ohm speakers and 100 watts per speaker, it can provide 40 volts. If you used 4 ohm speakers instead, each speaker could be given 200 watts at 40 volts, resulting in severe overheating and damage to the amplifier.
They are called "PA" speakers. PA meaning "Public Address" is a large loudspeaker design to deliver sound to a large group of audience. You'll often see these large speakers at clubs, concerts, and cinemas. There are two types of PA speakers. "Passive" and "Active" speakers. The passive speakers doesn't have a built-in amplifier. These speakers will require the use of a power source called an "Amplifier" to power these speakers. The active speakers have a built-in amplifier and doesn't require the use of an amplifier.
No, 15 watt speakers are rated far to low to be used with an external amplifier.
You need an amplifier for any speakers if they are to function.
Yes the as are pas iv not active
You should get a amplifier if you want good sound quality out of your speakers.
Amplifiers are rated to operate within a range of impedances. Typically, a domestic amplifier will drive a minimum impedance of 8 Ohms or 4 Ohms. Using speakers that have an impedance lower than the amplifier rating is likely to increase distortion and can damage the outputs of the amplifier if the levels are too high. Using speakers that are significantly higher than the minimum rating will not cause damage to either the amplifier or speakers but it will reduce the power that is delivered to the speakers. In most domestic systems, this limitation of the power output is not likely to be an issue. Any amplifier rated to drive into 4 Ohms will work well with speakers of between 4 and 8 Ohms. An amplifier with an 8 Ohm rating should be used only with speakers of 8 Ohms or higher.

Yes you can. Contrary to popular belief, an amplifier rated with a higher output than the speaker rating rarely damage the speakers. If the amplifier overdrives the speakers, the sound quality will be dramatically affected. Most listeners will turn the level down to reduce the distortion being heard. The amplifier's power rating is the maximum power that it can produce and it does not mean the output power will be at that level. On the other hand, an amplifier that is overloaded will deliver distorted signals to the speakers. At high power levels, the distortion can be damaging to the speakers in a way that simply over driving a speaker is not. Therefore, it is as safe to use an overpowered amplifier with speakers as it is an amplifier that is rated at the same power or even lower power than the speakers.

A combo amplifier for a guitar contains a normal guitar amplifier and one to four speakers. A normal guitar amplifier does not contain speakers, but is able to send the signal to a speaker cabinet.
There are a bunch of important factors to consider prior to buying an amplifier for a vehicle. Primarily, you must decide what the amplifier will be primarily used for. If the amplifier will be used for powering subwoofers it would be good to consider the bridged or mono capabilities as well as ohm ratings of the amplifier as well as the draw, or amount of power the amplifier will pull from the car's electrical system. The most important factor in considering an amplifier for powering subwoofers is probably output watts, which will determine the amplifier's power to the speakers and the amount of bass to be transmitted. If the amplifier is to be used to power mid or high range speakers, a multi channel (four or more) amplifier should be considered because of the ability to run multiple sets of speakers or component sets off of the different channels of the amplifier. The considerations inherent to the subwoofer amplifier are also present including watt ouput and power draw, but when selecting a multi cha
