FAQs

What does EVC mean for 5.25 inch kicker door speakers bass?

EVC means Extended Voice Coil. It allows more linear excursion for deeper lows without distortion. Kicker uses this in CS and DS series. Bass hits harder in door installs.

How does 90dB sensitivity help these speakers?

90dB sensitivity means they get loud with less power. Play at high volumes off head unit alone. No need for big amps right away. Great for stock systems.

Coaxial vs component in Kicker 5.25-inch models?

Coaxial tweeters mount direct on woofers for simple door swaps. Components like 51KSS504 separate tweeters for better imaging. Use components for custom soundstaging. Both hit 4-ohm impedance.

Typical mounting depth for door fit?

Most need 1.75 to 2 inches depth. CS series cuts it slim for factory grilles. Check your truck or SUV panels first. Fits GM, Ford, Dodge easy.

Frequency response range on these?

45Hz to 20-21kHz covers full spectrum. Handles bass kicks and crisp highs. Silk-dome tweeters smooth treble. No harsh peaks.

RMS vs peak power handling?

RMS rates continuous power like 50-75W. Peak like 200W is short bursts. Match RMS to your amp. Avoid clipping. See more on 2-ohms Kicker speakers.
