Generally speaking, amplifiers are designed with high input impedance so they don't load down or distort the input signal. Vacuum tube and MOSFET input stages are characteristically high impedance. Of course high impedance inputs are susceptible to noise because of the ease with which currents are introduced by stray capacitance or direct electromagnetic field interaction.

Hi I have a car amp in my room which is hooked up

Car amplifiers cannot be powered by laptop power supply. These amplifiers have different power ratings. You need to check the Car amplifiers power requirements / rating (Voltage & Current requirements) and then get a power supply with the exact same Power ratings. If the power supplied to the amplifier is less than the rated power it needs, it will not be able to drive the amplifier IC's and transistors in the amplifier and will not produce good sound.
Please check the power requirements for the amplifier and buy a suitable external power supply for it.

Running 2 external displays on a lenovo g570-4334

If the signal runs through the appropriate balanced amplifier, any number can be used. The impedance must remain at 75 Ohms!

I have a jvc stereo in my car, I just installed an amp but I don't get sound to the amp. I'm not sure which out puts to use and how to get them to work.

It depends on which head end unit you are using and which amplifier unit plus is it line level or power level feed.
Run of the mill, there is a signal output pair at the rear of your head unit. Run screened lead to the amplifier input.
If you get altenator whine, use a matching isolation transformer.
Hope that helps.

Can Acer laptop drive the Logitech S220 2.1 Speaker System with Subwoofer?

sure can, any standard sound amplifier can take a signal from the stereo earphone jack and amplify with fantastic results.

Just need to go to Radio Shack or Walmart, or another department store to get the right adapter (stereo to stereo, or stereo to mono) and cord.

Note the number of contacts on the earphone plug that plugs into the earphone jack. If it has three different connections on the plug, it's stereo. If it has only 2 then it is mono.

Most computers I know of have the stereo plug which works with stereo inputs of an amplifier.

So, the answer is a resounding yes.

I have sony laptop ; i want to connect speakers with .i have a question that if i do so then i need a amplifier or not ? if no then how much its max output?

No you dont need an amplifier. You can connect speakers without amplifiers to it. Even 2.1 and 5.1 can be connected without the amplifier. The max output will depend upon the speaker ratings, but I can guarantee you'll get sound enough to break your window ;)

I've connected like wise without amplifier and its working great.

Hope this helped. Rate it if it helped you.

I speakers to my laptop

You need an amplifier between Laptop/PC jack to drive the high power speakers/subwoofers. Or buy the special system like Logitech's Speaker system (speakers-subwoofer) that has a built in amplifier already designed for PCs/Laptops. Radio shack has amplifiers of various inputs and power levels.
