Frequently Asked Questions
How much does a car sound system upgrade cost?
A basic upgrade (head unit + speakers) costs $200-$500. A mid-level system with amplifier and subwoofer runs $500-$1,500. High-end custom systems can cost $2,000-$10,000+. Installation adds $100-$500.
Should amp watts match speaker watts?
Your amplifier should provide 75-150% of the speaker's RMS rating. Too little power causes distortion, while too much can damage speakers. Always match RMS ratings, not peak power ratings.
