Capacitors

Shop capacitors and capacitor banks for car audio and high-current electrical systems. Capacitors buffer short bursts of demand, which can help steady voltage during heavy bass notes and reduce headlight dimming on systems that draw hard in brief peaks.

A capacitor is not a substitute for charging capacity or battery reserve. If your system runs down over sustained play, the fix is usually a high output alternator, more battery capacity, or both. Capacitors work best alongside adequate charging, not in place of it.

Match farad rating and voltage to your amplifier draw, and upgrade cable to suit. Browse cable and wire for correctly sized power and ground runs.
