what would happen if i put 8 ohm caps on 4 ohm tweeters??

What exactly are you trying to do?

Resistors have resistance values, capacitors have farads (or microfarads, "uf"). 8ohm would be the value for a resistor, not a capacitor

i got a cap from radioshack to block freq below 4khz for my tweets but they say 8ohm on the box and my tweets are 4 ohm...actually this is it right here...

4.7"uf" electrolyte capacitor

n/p
x-over: 4khz @ 8ohms
50v max
axial leads..

is this ok??

Ah.....I see what you are saying. No, that will not give you an xover point of 4khz for a 4ohm load. Using that cap on that 4ohm tweeter would give you an xover point of around 8000hz. For a xover point of 4000hz with a 4ohm load, you need a capacitor with a value of 9.95uf. Also keep in mind using a cap only gives you a xover slope of 6db/oct.
