ICE All About Amps

Firstly, What actually is an amp?
An amp is commonly a standalone piece of equipment, which given power and a signal, will produce a powerful speaker output that drives your desired speakers. You will also find an amp in your headunit, albeit a less powerful one.

What can an amp actually do for me then?
Quite simple really, it can produce a much clearer louder signal to drive your speakers. Amps provide a much higher clarity and depth of music over the average headunit. Some speaker types (subwoofers inparticular) rely solely on a standalone amp to run as they require a lot more power than the amp in the headunit can provide.
