Q:How do I tell which wire is positive and which wire is negative on the door speakers and the rear speakers?

Unplug the wires and note which wire goes where. then apply a battery to the speaker terminals, 9volt will work fine. If the cone moves out you have it connected to the proper + and - if it moves in then its backwards. With that you should be able to figure out which wires are + and -. Or you can just buy a service manual.

Q:i Have a problem with my xeno portable dvd player..the ribbon wire inside is damaged..can somebody tell me where to buy a ribbon wire?

Electronic parts stores carry ribbon wires, but there are many different kinds of ribbon wires, and they would have to look at the wires in the dvd player to know what kind you need. The biggest problem with the wires is connecting them to the circuit boards. An electronics repair shop might have a piece of ribbon wire they can adapt to fit your player. .

Q:My computer kept switching all the time when ever I was playing a game. So I had alook in my computer and a wire I bought to extend the CPU wire. The extended wire had burnt so bad that the wire was showing out of the insulting. Will this effect my computer in any way because it was working fine and I shut it down before I took the wire out does it matter that my psu only has a 4 pin for CPU and my motherboard has a 8pin?

Could fry components if it gets out of hand?

Q:hiI got a car radio quot;Grundig WKC 3680to stick to my car, I don't understand is the difference between : 12 VOLT BATTERY WIRE and 12 VOLT IGNITION WIRE, which one to use? I got only one cable bringing the current from my Renault 4 car!thanx

check to see if that power lead from your car has power with the ignition off if it does that will be your memory wire and you will need to run another wire from your fuse block on an accsesory that is controlled by the ignition switch for the cd player to be able to turn on and off with the car its not a very hard job once you figure out the starting point

Q:I recently Hooked a newer Pioneer cd player up in my 00 mustang gt!.. it will not keep memory. The only way it will come on is when the red(power) is hooked up with the Yellow wire!.. but this way it will not hold a memory.. theres a few orange wires but i have hooked them up and it still wont keep memory? any suggestions?

Chech okorder ... The red wire goes to the ignition 12 volt source, and the yellow to the battery 12 volt source. The yellow wire must remain hot with the key out to retain memory. There may be a bad fuse for the battery wire. It is usually fused through another circuit such as the cigarette lighter, clock, or horn.
