"Consider car audio as an enjoyable hobby that can be pursued at a reasonable cost. I started with a minimal budget and gradually upgraded to a mid-level system. However, instead of dramatic changes, I've noticed that the sound quality improves and the tone changes slightly. Of course, this is just my personal opinion. If you don't have a lot of financial leeway, learning how to set up a DSP (Digital Signal Processor) on a decent system to experience changes in sound and to find the sound characteristics you prefer could be more effective and enjoyable. I think you will find more fun in this approach."
