Installing tweeters with with Amp

I want to hook up some tweeters to this 4ch amplifier I have, along with my mid range co-axles. The amp has two crossovers, including one with a HPF that allows frequencies above 80hz. This is the "side" of the amp I would like to use for my tweeters (4 of them). Should I still use the crossovers ("bass blockers") that came with the tweeters? Or hook the tweeters directly up to the amp?
