  1. Would you have a schematic that reflects the wiring from the amp located in the trunk to the speakers. I am installing a powered subwoofer in a 2008 SS Impala. Any pic’s would be helpfull. Excellent Web site. Thanks

  2. I am trying to hook up my amp in my 2008 impala Lt3 and I dont know where the best place to run the power wire through the firewall. I thought about drilling a hole but I dont know where to drill and where not to drill or is there already a hole through the firewall I could run the wire through. any ideas would be helpful. thanks

  3. Scott, most vehicles have a factory hole with a rubber or plastic grommet at the firewall. This is usually the standard place to run a power wire through the firewall. If one of these holes are not available or not large enough, a hole will have to be drilled to accommodate your power wire. Choose something on the engine side of the firewall as reference and try to match it up on the interior side of the firewall. This will make sure you don’t drill through anything important. Then drill a hole somewhere near or beside your reference point. Hope this helps. Good luck with your amplifier installation.

  4. I bought a 2008 Impala ltz about 8 months ago, My wife drives it most, but I do also. My only serious complait is the AM/FM radio reception. I live within 15 miles of St. Lous, and a large number of stations I can pickup with my other car, seem to have weak reception. I uderstand the antenna for this system is acutally the rear window defoster wires. Is this reception problem common to all 2008 Impalas, or do I have a problem with my individual car. If it is not common, any suggestions as to a fix. I do not subscribe to Satellite radio, and don’t necessarily want to. Thanks.

  5. Leo, it seems that a number of late model vehicles that have antennas in the rear window seem to have very weak radio reception. Unfortunately, there is not much you can do other than have an experienced mobile electronics installer put in an aftermarket exterior antenna that will replace the window antenna. This will probably get you better radio reception. Hope this helps. Good luck with your 2008 Chevrolet Impala antenna troubleshooting.

  6. How do you remove the right rear speaker for replacement on my 2008 Chevy Impala LTZ? It has a buzz periodically and then will be fine for a few days. Need to see what’s going on.

  7. Wayne, you can get to the rear speakers on most late model cars one of two ways. You can remove the rear speaker grills from some vehicles simply by removing screws that hold down the speaker grills to the rear deck lid. These screws are usually located on the bottom side of the rear deck (accessible through the trunk). The second way would require you to remove the deck lid from the interior of the car. On some cars removal of the rear seats is required to get to the rear deck lid. Hope this helps. Good luck with your 2008 Chevrolet Impala rear speaker removal.

  8. My rear deck has to be removed from the inside of the car. My rear seats both fold down so getting to the deck is no problem. I cannot for the life of me see anyway to remove the rear deck though. I even had a local paint/body man look and he could not figure this thing out. Thanks for any additional input!!

  9. Corey, technically you could connect your 2008 Chevrolet Impala amplifier turn on wire to a switched 12v+ power source. That way your amplifier is on whenever your 2008 Chevrolet Impala is on and off whenever your 2008 Chevrolet Impala is off. Run a primary wire from the back of your radio to your steering column and use the brown wire in the ignition switch harness. This brown wire will provide a switched power source for your 2008 Chevrolet Impala stereo. Hope this helps. Good luck with your 2008 Chevrolet Impala stereo installation.

  10. I recently bought a 2008 Impala and the front speakers door speakers worked fine for the first two months. One day I noticed they were not working at all. I also noticed the seat belt chime was not working either. I assume it is played through the same speakers. After about a week, the speakers came on and now they only work sometimes. I think there may be a short or loose connection somewhere. Has anyone else had or heard of this issue? If so, where may this issue be because it is very expensive to have someone look at it!

  11. Jessica – I have the exact same problem with the same car. The dealership told me that the front speakers were bad. I sure hope that is the problem. I would hate to buy new speakers and find out that the problem is with something else.

  12. great site thanx for all the info. i have a 2008 chevrolet impala ls there is no amp in the back i am in the middle of looking for a 12v swich wire. thanks to this site.. i now know but what is the pink amp triger wire for.

  13. Michael, run a primary wire to your steering column and use the brown wire in the ignition switch harness. This brown wire will provide a switched power source for your 2008 Chevrolet Impala stereo. Hope this helps. Good luck with your 2008 Chevrolet Impala stereo installation.
