When it comes to car sound system, imho only 20 percent goes to the equipment you will be using regardless of brand. Another 30 percent to the placement of speakers. Example. Tweeter sounds better when it is placed on the dash of a 1st gen to 2nd gen vios than on a stock tweeter pod t the back of a side mirror on most cars. 45 percent goes to tuning of the car. This is the hardest part too. I once used an alpine 3342 car dsp and replaced with a audiocontrol eqx. Yes i am old. and the remaining 5 percent goes to how you hear music. It differs kasi from one person to another. One can be satisfied with a 40k budget while one person isnt with a 200k budget.
