[QUOTE="Lasherž, post: 8703901, member: 679555"] In this case you're trying to prevent a power spike rather than a sudden power loss. The pop is happening due to a voltage drop disappearing. Capacitors are usually thought of to reduce voltage drops, but they also reduce transient spikes. Depending on where the pop originates (amp or head unit) I'd put the capacitor in parallel with the terminals of that device. Alternatively you could put it in parallel before the switch on the light. If you want to get a more dramatic result from less capacitance you could also use a transient clamping device like a crowbar which acts like a zenner diode to divert voltage to a capacitor when it gets above a certain threshold. They make premade devices meant to go on 12V wiring for this very problem that use the crowbar latching method because it requires less capacitance for the same result, it just doesn't help stability for drops, only spikes.
