The 2005 Chevrolet Impala is the eighth generation of the Impala model and its horsepower ranges from 180 to 200. They were built and released from 2000 to 2005.
The radio has a security system to prevent theft. You will need a reactivation code from the dealer to allow it to work again
What size engine.
There isn't one.
It is in the gas tank.
I have a 2000 impala and installed an aftermarket radio and amps. First you need to remove the fuse covers on both sides and find the screws that hold the dash in place. the dash will have to be removed in order to access the stero.
