Is A Capacitor Needed For Subs

Capacitors store energy so the voltage of your electrical system doesnt drop at such a fast rate when an amp requires a lot of power ie. Capacitors do nothing but smooth the power signalthey should never be added to a system as a fix for light dimming.

Small overages can often be helped with a capacitor while large overages need the upgraded alternator and battery.

Is a capacitor needed for subs. If your lights dim upgrade your ground from your amp your battery to ground and your battery positive to alternator. The capacitor will help ensure your music does not go flat but has the dynamic quality you love. Like i say i wasnt sure what i needed but i found out that some systems need the capacitor.

If you want to install a power capacitor be sure to read the article on car audio capacitor installation. Imo a cap isnt ever a necessity and certianly not in your case. Full charge will be about 500 microseconds.

Depending on the degree of additional current you need this can cause the dimming headlights syndrome. Car audio capacitors are a great addition to any aftermarket audio system that is in need of a little extra power. A capacitor that is too small will fail to provide energy when it is needed while an oversized unit can cause unnecessary power drains and overload the electrical circuit.

Just make sure the amp wiring is done correctly 8 ga pwrground and you should be good to go. The capacitor will smooth out the peaks in current draw from your amplifier during peaks in the music. So i was just wantin 2 make sure.

Capacitors store a temporary electrical charge that can be released during periods of extra power strain. If a vehicle has dimming headlights when music is played a capacitor could solve that problem. Dont worry about a cap.

Practically however it can be considered fully charged after 5 time constants. Ad a subwoofer capacitor is often installed in audio setups that use large amplified subs for bass. A bass note i just hooked up my friends 2 kenwood 400w rms subs in parallel last night and hes got a 2000w amp and his headlight dont even dim that much.

A capacitors stored current can give quite a shock if mishandled when it is fully loaded. One time constant is farads times ohms so the time constant for a 10 microfarad capacitor and a 10 ohm resistor is 100 microseconds.
