Whenever you are planning to upgrade something on your vehicle, it's always wise to set up a budget before you spend a cent. A solid budget will immediatly determine the price range of the product you will eventually buy. Once you have a budget the next step is to look at the current state of your cars audio system. Lets assume that the system is stock. In 96' Commodore, where do you start? Generally the first thing that you should replace is the head unit, as it's directly responsible for the sound quality of your entire system, despite the fact that it's more expensive than replacing the dirty sound through lousy speakers. But remember, the sound will still sound dirty through quality speakers...Basic No1
An aftermarket HU has a more powerful built in amplifier designed to drive four speakers and usuall will have a rated power of 50Watts Max per channel and about 15-20Wrms Most OE headunits have a TOTAL of 25wrms between all four channels :S
The peak power of a HU is typically the most advertised but that is somewhat misleading, as the maximum power rating is not a constant rating and only occurs during dynamic points in the music. So does this mean that more power is better? No, not exactly. But aftermarket HUs produce more power with less distortion. Remember this - harmonic distortion is like detonation in an engine; it can cause damage if not controlled. Many people with stock speakers end up replacing them due to a buzz or rattle that soon develops. What they don't realise is that the distortion from their headunit and high volume levels have damaged the voice coil on the speaker or have caused overexertion in the cone of the speaker resulting in physical damage.
Feel free to ask any questions....
