If you are thinking of replacing or upgrading your original factory fitted car radio but are unsure of the options, benefits and technical considerations, then read on, all will be explained.

Factory-fitted radios (standard fit radios) in the past had relatively low power outputs of about 3 to 5 watts RMS. However, the latest factory-fitted radios have improved vastly with power outputs of up to 100 Watts. These figures represent 25 Watts, ‘peak’ power per channel x 4 (this basically means x 4 speakers).

This actually translates to approximately 10 watts RMS x 4 channels, when used for any length of time (continuous). Is this power substantial to produce high quality sound? Yes and No

Compare this to aftermarket radios (radios manufactured for retail sale), such as the best-selling Alpine, Kenwood, Panasonic and Sony brands, where basic models start at a power output of 45 Watts x 4.

Why am I telling you about factory-fitted radios if you are about to replace it?

I am telling you about factory-fitted radios because if you really wish to keep your radio you can, by adding a CD changer. This gives you the option of CD and/or MP3 at way below what your dealer would charge. This can only be done if your radio has a CD Changer output socket found at the rear of your radio.

Now, if you feel the factory radio must go, ensure that the aftermarket radio you’re planning to install has all the features you need. Furthermore, ensure that it is easily compatible with other units like CD changers. This is very important because you never can tell when you’ll want to upgrade your car audio system. Then you won’t have to spend on interfaces to enable you connect your new unit.
