96-98 civic front speaker Q

[xtant]

I know with after market 6 1/2" speakers you have to cut out the plastic so the magnets fit, But that plastic that is cut out seems to protect the stock speaker from getting wet. So if that is cut out how would I protect my new speakers?
Instaling the speaker is not a problem I just don't want my Infinity Kappas getting wet. Any experience or knowledge would be greatly appreciated. Thank you

you could just make a spacer for it.
