How to install a bass blocker capacitor for car speakers | Crutchfield

Some full-range car speakers sound a lot better with an inline capacitor, or bass blocker, installed that helps filter out low frequencies the speaker may struggle to reproduce. They're especially helpful if you have subwoofers to play the low notes anyway, and with one of these simple crossovers in place your system can really sing.

Some speakers come with these in the box, but you can add them to any speaker you want. Check out our selection: https://www.crutchfield.com/i-rYTVc2N...
