What’s the sensitivity for amp-free volume?

Kicker 51KSC6504 hits 90dB 1W/1M. JBL Stage uses Plus One for 2dB gain. Higher dB means louder play from stock radios. Great for daily drives.

How do 2-way vs 3-way designs affect sound?

2-way coaxials like JBL Club6520 focus woofer-tweeter blend. Kicker DS 6×9 adds midrange for fuller spectrum. 3-way fills gaps in vocals. Pick by door size.

Impedance safe for car stereos?

Most run 4 ohms, some JBL at 3 ohms. Matches standard head units. Low impedance draws more power for punch. Check amp stability. See Kicker car audio setups.
