What diameter hole saw is needed to drill the custom brackets?
kc in va  Jun 20, 2022

If you need to get your tools in line before install, we got you covered K C! I show on these Kicker 46CST204 CS series tweets you will need a cutout of 1.570" if you use the flush mount cup. You will need a cutout of 1.685" if you use the angled flush mount. Surface mount of course, no hole saw needed.

Nope, had to buy the wire connector,(forgot number) after hooking up the new wire it sure made a big difference, it only cost, I think about $10.00. Good luck

yashida  Dec 03, 2019
How do you adjust the passive crossover? I see it is covered in a rubber protective tubing. Is it a switch or a knob? What is the ideal adjustment? Thanks.
brian  Aug 05, 2019
2 answers
There is no adjustment. They are purchased at a frequency and everything below that frequency is cut off from going to speaker
jacob daniel  Aug 02, 2020
