Why Car Audio Systems Require High-Current Batteries

Music contains dynamic peaks and transients (like bass drum hits and explosions) that demand instantaneous high current delivery for accurate sound reproduction.
High-power speakers require substantial energy. With fixed 12V automotive systems, achieving high power (P=V*I) necessitates large current flow.
Example calculation for 1000W peak power: I = P / V = 1000W / 12V ≈ 83.3A
Low-impedance speakers (2Ω or 4Ω) draw more current according to Ohm's Law (I=V/R), with 2Ω speakers requiring twice the current of 4Ω at the same voltage.
