How many speakers would you need for a quadraphonic sound system?

In theory, four. 'Quadro' means 'four'. It's a four-way system.
In practice, anything between four and six. Designs with a center and a subwoofer are sometimes called 'quadrophonic', because they don't truly receive a 5.1 signal, but rather - derive the low frequencies using band-pass filters, and get the 'center' signal from somewhat-merging the front-left and front-right together.
Do keep in mind that anything driven from a stereo output is stereo, no matter how creative the hardware designers get. Pay attention to the number of jacks you get with a particular sound system - a 5.1 system will have three or four (good quality systems will also sport an S/PDIF connector, through which a 5.1 audio signal encoded using Dolby DTS or some other system can be sent), and a quadro system should have two stereo jacks.
Also, remember that in order to get more than two speakers, your amplifier/primary stage/device/computer must also feature more than one output for this purpose. If this is a PC, the software used for playback must also support these features. Regardless of the device, the source (DVD, music file etc.) must also provide more than two signals encoded on them, in order to enable quadro, 5.1 or 7.1 speaker configurations. If the DVD you're playing has only stereo sound, you'll only get stereo.

Best car speakers?
Which car speakers are the best is a opinion. Though a specialty sound system store can help someone figure out which speakers would be the best for their vehicle and what they want.
How do I get the sound output from home theater while watching normal TV Is it possible to get the sound output from both at the same time. Ii tried using a 3.5 mm jack but it didn't help?
I can't help you with the connections with just the info provided but I can tell you that you should not have the TV's speakers on at the same time while listening to the sound system speakers. I would mute the TV's speakers (go to the audio menu and turn the internal speakers off) and always use the sound system speakers.

What are the stock speakers for a 1987 ranger?
since it is an XLT, and i have a 89 ranger XLT, when i was working on the sound system i took them out and i am pretty sure they were JVC, but that was long ago and i am not 100% sure. But i am sure i got the premium sound system when i bought it, they would be different if you did not get the premium sound system.

This could be any number of problems. Check to make sure that the power cable for your speakers is plugged in first. After that it could be any number of issues from software to hardware.

What would you hear if you listened to music played back through two out of phase speakers?
It may or may not be possible to detect that a pair of speakers are connected out of phase just by listening. Generally, it isn't. But it is a good idea to insure your speakers are correctly connected to the amplifier.Both speakers and the speaker output terminals of amps are tagged with positive and negative. Hook them up correctly and avoid "weirdness" in your sound system. There are actually electronic devices that check for polarity, but they are a waste of money. Use your eyes and your brain to insure your speakers are connected correctly and be done with that portion of "tuning" your sound system.
Can I use my desktop computer with home audio speakers?
Yes, you can connect your desktop to your home audio speakers. The audio cable would go from your sound card to your home audio receiver which in turn would play out of the speakers. However, it would be much easier to use your desktop computer sound with desktop speakers. Desktop speakers can be plugged directly into you computer through a usb cable or audio cable and are available in a two speaker set or surround sound set ups. anonymous@oola.com
Do you need a sub-woofer for surround sound?
Not if you have full range speakers like tower speakers. Even with large speakers, the surround sound mix is encoded with LFE (low frequency effect) sounds that would not be heard without a subwoofer.
