Ok heres the problem...
My system worked fine until about two weeks ago when i noticed a speaker popping in the back of my truck. When i switched the speakers from side to side to make sure it was a problem with the speaker, the other one did the same thing. I do have continuity from the connections at the speaker to the connector at the head unit and my other speakers work. What is wrong here. If it is the head unit (it must be?) whats wrong and how do i fix it? thanks

actualy i had a similar problem in my 2003 ranger. worked fine with stock HU but then when i installed the aftermarket HU the rear passenger speaker started poping and so i replaced the rear speakers with aftermarket speakers adn it did the same thing... not sure what it was but something with the stock wiring wasnt compatible with the aftermarket HU. when i put the stock HU in then it sounded fine...
i ran new speaker wire to it and it sounded fine...
my suggestion would be this pull the HU out and hook the speaker directly to the back of the hu to the channel that is messing up... if it still pops then its the HU if it sounds fine then its the wiring...
if it is the hu then i suggest trying to get it fixed under warranty.
if its not still under warranty then one of 2 things either take it to an authorize shop and have it fixed or buy a small amp... a 4 channel amp that puts out under 50watts of power per channel can be had for less then 100$
at www.thezeb.com they have 2 profile brand amps both 4 channel one for 80 and one for 85 both around 50watts rms... with a bit of shopping you can probaly find a 40watt rms per channel amp for around 60-80$

ok well i took out the head and had it in my house overnight... when i reconnected it the speaker worked. However, after leaving it in the car for a few hours, the speaker didn't work again. I think it may have something to do with the cold but i don't understand it. any help would be great

cold isnt going to do it there is nothing in the head unit that normal temps are going to effect....
i would bet anything this is a wiring issue . test like i listed above to track it down
firsttest then speaker right off the back of the HU if it works hooked directly to the speaker wires coming out of the deck then its the wires if not then its the HU....
honestly it sounds like a loose connection somewhere when you took it out and moved it around then reinstalled it the speaker worked untill it moved again and started shorting out or rattling loose.
but the only way to be sure is to test the speaker right off the HU's wires for that channel.

Hummm, in most cases Chronos gave the proper tests to perform basic diagnostics. However, if you took the HU out, brought it into the house to warm up and it worked just fine for a time, I'd have to say that some internal components or solder joints in the HU are suspect.
If it worked fine after being in the house for a time, that somewhat rules out wiring problems. That can easily be tested with the HU out, speaker connected and use an ohmeter to test resistance on both rear speakers from front dash wiring. Expect to read about 3.5 ohms off each speaker line. If one is way off that number, a wiring problem is likely. However, if the ohmic test is good, everything points to the HU.
How old is your HU?
