BB398 10 Percent Cap 398Uf 100Volts 85 Hertz 4 Ohm Non-Poplar,White/Red

Takes the low frequencies out of my car speakers

The 398uf capacitor set perfectly "high pass" filtered out 100Hz and below from my 6x9 4 ohm peakers. My old infinity 3-way speakers on Dodge had defective tweeters(just too old), but mid bass sound great. I removed tweeters on them and used these capacitors to bring speakers back to live as my garage car stereo system. You can buy capacitors and make your own filters. I miss the radio shop where I could buy electronic parts before they closed down.

Bought these to filter my front 6x9s after adding a subwoofer. They did exactly what I was looking for in keeping the sub bass frequency out of my front stage. Now I can enjoy a higher volume with less distortion.

These did exactly what I needed for my pioneer 5x7/6x8”s filtered the distortion low end frequencies and gives me a touch more volume and clarity to my OEM Mazda 6 head unit.

These do exactly what I bought them for. Overall they are bit bulkier than they look online, but not so much that it interfered with my install.

Did a decent job of cutting the low frequencies out however a little too much still comes through.

hooked these little pups up to my woofer output on a crossover for a 6.5 inch Audison AV speaker, no noticeable difference when playing music. Definitely no difference with a test tone generator. Maybe I didn't do it right?? uhh..

Used these capacitors to create a high-pass filter at around 80-100 Hz for my stock head unit in my car. I have 2x 12" subwoofers and did not want the low frequencies rattling my door speakers. Capacitors essentially create a static crossover. Very accurate capacitors with almost the exact same roll off on each unit. Non-polar is a must, and the heat shrink was a plus!
