Default Homemade Bass Blockers

Hi. I am replacing my head unit and stock amp and have the need to install bass blockers on my front tweeters. My speakers are 2 ohm ones. Can anyone recommend what rating Caps I should use as bass blockers? My HU outputs 50W per channel peak. I really have no idea what cutoff frequency the tweeters should be handling. All examples I have seen mention 4 or 8 ohm speakers, and the math is so confusing....
Thanks for the help!
Jim

Default Bass Blocker Calculator

Hey, thanks for the link to the calculator. I appreciate it!. Still trying to figure out at what frequency to cut off at, and the power size of the caps. I have a 50Wx4 radio.

That website if full of good information! How do you absorb this much info?!?
