I inherited a Bose system, unfortunately the audio cables have lost the little red sheath identifying the positive cable. I'v been tearing my hair out reversing contacts on the speaker side trying to get the system to work, at this time I still have the rear speaker outputs reversed, i.e. sound that should be from left side comes from right and vice versa ( Bose has a setup CD that helps you determine if the system is set up right.

The best way to determine polarity and location on a speaker interconnect with multiple unmarked wires is actually best accomplished with a battery. Yup, you're not hallucinating and I'm not crazy- read on: get a 1.5 v dc cell, aa, c, or d, and pull all your grills IF they are designed to come off. Pick a pair of speaker wires, and put one on the flat side of the battery (that's the "-") and then touch the other to the positive side (the battery has a protruding bump on that side). If those wires are going to a single speaker, that speaker will make a clicking or popping sound- but fear not, the battery lacks the power to damage the speaker. Now you have the location, so TAG THE WIRE before proceeding. After that, you must be able to see the cone of the speaker to determine polarity- if the grill is not removeable, get a flashlight and shine it through the cloth at an angle so you can see the cone. Have someone else do the battery thing WHILE YOU WATCH the speaker. If the cone sucks in, polarity is reversed- if the cone pushes out, polarity is correct. Remember, the bumpy side of the battery is positive. MARK THE WIRE. Red heat-shrink tubing is widely available. Drop a piece of it over the positive lead for future reference. Polarity is important because speakers that are not running "in Phase" (hooked up the same way) will cause two problems: first, the bass will sound cheezy. Secondly, in a home theater especially, the sounds will come from the wrong place. If things still don't work correctly, consider the source- literally. There may be issues with the line-level sources feeding the bose unit. Computers can be especially wonky- DIVX and other dvd playback software can be very unpredicatable with a test disc- but that's another story. Hope this helps.

Doesn't sound like a polarity issue. If I understand correctly, you seem to be unable to locate which set of wires relate to which speaker.
If that is the issue, there is simple way - get hold of a 1.5 battery (take one out of any remote) and then start connecting the wires one by one. The pink noise it generates will identify the speaker you are connected to.

umm dont sound like u have a polarity problem
speaker cables arent polar, and even if u have them reversed from the speakers to amp, u will still get sound.
Now whats going on is that u have the left speaker cable plugged into ur right speaker and right speaker wire to the left speaker.
simple fix, reverse them on them amplifier end. and u should b golden.

hey, hey, hey. polarity matters when it comes to speakers. why all speaker manufacturers will color coded their speakers if polarity doesn't matter? if you reverse the polarity the speaker will still function BUT the cone movement will be reversed instead of throwing the sound it will be in opposite (in simple english)
anyway, your problem might be speaker position. just connect your speaker one by one. if the position is wrong then connect it to the next terminal until you get the correct position. then do the same with the other speaker.

polarity isn't your problem because it would wokr either way. you have the speakers plugged into the wronng intputs. You to switch the the whole speaker wire. if that doesn't work just put the L speaker on the right side and R speaker on the left

they will often use unmarked cars and 'unmarked locations' as well (i.e a speed camera site which has no advance warning signs of such thing) cos of course it's all for the money revenue rather than actually caring about road safety properly but like others have said it can more often be just ANPR cameras/checks rather than just speed checks so as long as your legal to drive (correct license, insurance, mot, tax etc) and your cars in roadworthy condition than you'd have little to worry bout but regarding speeds, just keep your wits about you cos they'll do anything these days to catch us out and brainwash us into believing the crap they say about speed kills etc
