Why should you upgrade the speakers in your car and why:
There are many reasons why you should consider changing the speakers in your car. If it is an older car, and you do not have tint, the speakers probably took a lot of UV damage from the sun and has deteriorated. Older speakers are also single cone speakers, made out of paper and are not coaxial. Coaxial speakers will have an extra tweeter or midrange on top of the main woofer to give you more highs (voices, and instruments)
Speakers come in different sizes, and come in standard sizes. They start from 3.5 inch on up.
Below is an example of 3.5 inch speakers:
The most common speaker sizes in cars are 5.25 speakers (smaller)
and 6.5 inch speakers
and 6×9 speakers which are in the rear of cars
Most Fords will use 6×8 speakers. 5×7 speakers and 6×8 speakers are interchangeable. Do not mistake 6×8 speakers for 6×9 speakers.
Speakers can also come larger than 8 inches. These are still car speakers, but typically are called subwoofers or car subwoofers. They range from 8 inches to 12 to as big as 15 inches. The larger the subwoofer, the deeper the bass.
Sometimes the subwoofers come in boxes. Which means you do not have to make your own box for it, and it is tuned to the subwoofer. This makes things a lot easier
Speaker adapters are available for some cars to make them fit. For example, a 6.75 adapter to make 6.5 speakers fit in a 6.5 opening.

Car radios , when to upgrade and what is needed:
You should consider upgrading your car radio when it is missing a feature you need. For example, you need to add Bluetooth for calls and streaming, Navigation GPS, DVD player, aux in, CD player, Mp3 capabilities or you want to add more power to the existing radio.
Here is an example of a Double DIN Pioneer radio, which would add a ton of features to your car, along with navigation GPS.
Along with the radio, you will need a dash kit to make it fit into your car if it is not a standard din or double din size. Din size openings are 7 x 2 high and double din openings are 7 x 4 high. If you have these standard sizes, you can just buy any standard din or double din radio.
Some examples of DIN size radios below
Some examples of Double DIN size radios are below
A dash kit is usually needed to fit any radio into NON standard openings. These kits are specific to make, models and years. Be sure to pick the right one and check for compatibility. They come in all shape and sizes.
There are also less expensive dash kits which will cover a wide range of vehicles. (for example, a honda kit which will cover the majority of Hondas). Since these kits are so universal, it is also less money.
If you have steering wheel controls in your car, find a radio with steering wheel controls and then you will need a steering wheel interface to retain it also. This is optional
