Well, after installation of audio system, I noticed how my temperature on the screen always shows somewhere around 7 degrees. Thought it was just a weather..

Well tonight, I am pretty sure it's way below than 11 degrees... when I start the car it was showing 11 degrees, as I drive, the temperature went down to 3-4 degrees. Is this suppose to be like this? or is the temperature suppose to be at around what it actually is when I start the car?

Only modification I have is 5 channel amp and speakers in front door, woofer, and T1R voltage stablizer..

Thanks in advance.

no, the temp on the XM radio station for city info and stuff. Today it was like 86 out and the temp gauge said 99.

You know what? You can't really rely on XM for your temp readings. I noticed that different cities no matter how far or close they are to your home, they will always have a different reading! It just depends moreso on your location!

For instance, I live in Hayward....Union City is about 5-10 minutes away from me, but there is always a slight temp difference between the two cities! So, you can't really rely on weather channel/radio to tell you what the temp is! It all depends on your LOCATION! =) Since Hayward is a pretty big city, I notice some temp changes within the city! So, that tells you right there that it shouldn't matter where you get the temp info from...it's all about the LOCATION! :grinno:

I would have to agree with Shay...get a mercury thermometer and check the actual temp at YOUR location. Then use my post (post 61) to adjust your temp sensor if needed. It is possible that the voltage stabalizer threw off the readings, just remember that the temp sensor IS reliant on electrical current. (Maybe itz more accurate now

)

^^^ Yeah, I meant to emphasis EXACT location...not location! haha Temp should be measured at your EXACT location!

The temperature being off has to do with heat soak. If your engine has been running recently then the heat from the engine heats up the entire engine bay including the temp sensor for at least an hour or more after you turn it off. So if you get back in and start it it will read higher due to heat from the engine. After ten minutes or so of driving the wind will have cooled down the front of the car and it will be more accurate. A better location for the temp sensor woudl have made all the difference...
