Why Does Car Audio Always Sound Bad After Modification?
For music lovers or ordinary car owners, wonderful music enhances the driving experience. Modified audio sounding poor often requires tuning assistance. The quality of car audio modification depends not only on product quality but also heavily on modification skills. Car audio modification is complex; it requires good equipment, soundproofing, proper matching, correct installation, and tuning. Even identical equipment can sound subtly different depending on the installer/tuner. The complete modification plan, configuration, and even wiring must be known to diagnose poor sound quality.
Statistics show modification costs range from ~1000 to ~7000 RMB. When discussing car audio modification, many admit they aren't audiophiles, just wanting modest improvements without spending much. Choosing a modification shop often means "choosing the cheapest," forgetting "you get what you pay for," leading to dissatisfaction.
Let's analyze why modified car audio often sounds bad:
Inferior or Counterfeit Equipment
Many counterfeit or substandard components flood the market: fake brands, uncertified domestic parts failing quality standards. These have low specs and poor quality; some produce noise immediately, background noise during playback indicates poor SNR from inferior circuits, posing safety risks. Some install seemingly good-looking cheap systems using mostly counterfeit parts. The sound quality is predictably poor, noisy, distorted.
Such parts often lack specs, origin, or manufacturer, sometimes faking US/Japanese brands. They have poor frequency response, creating flaws during playback, failing to reproduce music fully. Installing an active subwoofer can muddy the overall soundstage. Good audio should have clear high/mid/low separation, like clear water. Installing many poor parts is worse than installing fewer high-quality ones.
Equipment Mismatch
Modification isn't stacking famous parts for good sound. One user installed genuine international brands: twelve speakers (three subs), three amps. Volume couldn't increase, noise persisted, sub box design was flawed – primarily equipment mismatch and improper use, plus poor installation/tuning wasted the system.
A good system configures parts to maximize potential. Some think same-brand parts are best.
Low-Grade Equipment (Even Name Brands)
Name brands offer low/mid/high-end products. Low-end parts are cheap. E.g., a low-end single-disc CD player + two low-end speakers costs ~1000 RMB. Users see the brand, not knowing it's low-end or mismatched. Low-end speakers (sometimes lacking tweeters) suit small-power tape decks; low power, high sensitivity distort easily at moderate volume, failing to reproduce CD quality well. High frequencies sound worse – harsh, lacking control; sometimes "popping." But sellers don't disclose low-end sound quality, exploiting users' desire for cheap name brands.
Poor Technician Skill
Most car audio is semi-finished, requiring professional tuning. Many technicians lack training, merely connecting parts simply. Wrong soundstage positioning, phase errors, installing amps without fuses risk fire.
Inadequate Tuning Skill
Tuning is the final crucial step. Some technicians barely understand equipment principles, can't use devices properly, haven't heard real instrument sounds – how can they calibrate? Tuning requires professional audio knowledge to optimize the system.
