What size factory speakers comes with a 2004 Chevy Impala?

The 2004 Chevy Impala came with several different sound system options, so the factory speaker sizes varied. You'll need to determine which sound system your specific Impala has to know for sure. However, common sizes found in the 2004 Impala include:

* Front Doors: 6x8 inch (most common) or sometimes 6.5 inch.

* Rear Deck: 6x8 inch (most common) or 6x9 inch.

To find out definitively what size speakers are in *your* 2004 Impala, the best approach is to:

1. Visually inspect the speakers: Carefully remove the speaker grilles (usually just pops off) to see the speaker itself and measure it.

2. Check your owner's manual: This should specify the audio system installed in your vehicle.

3. Look up your VIN: Using your Vehicle Identification Number (VIN), you might find detailed specifications on a Chevrolet parts website or a vehicle history report service.

Without knowing your specific trim level and audio package, it's impossible to give a definitive answer.
