My present car has one of those fine modern audio packages that any car owner or enthusiast could dream of. I got to soup it up and luckily, for me, every modification panned out pretty well. This is a rare thing.

Before that, the car that I got was somewhat archaic. Not that it was a bad car but its sound system was sufferance. The audio system had the classic AM and FM radio. This is the sort of car one will say belongs to the museum. This was before the existence and advancement of smart screens. The audio signal and sound were so week that when the car engine is purring or the cooling system is on you can hardly hear a clear sound.

The sound system of my car is what I am fond of for certain reasons. One of them is that music helps me focus and drive safely. The other is that it keeps me company and makes my commuting experience a pleasant one while on the road. This prompted me to wire the 4 channel car amplifier around the car. The 4 channel amplifier puts out high-quality audio in four separate channels. In other words, it can be used to power a pair of full-range speakers.
