speaker problems

Workin on a '01 s-10 crew cab.....i am trying to replace my front door speakers. I took aftermarket speakers from an integra and I didnt think the process all the way through. I thought I could remove the old speaker and put in the new one. But the plugs do not match up. Is there an adapter I can buy or am I out of luck....Thanks

see what Radio Shack has, and any car audio place.

I usually just replace all the wires, bt I've also just cut the ends off, and replaced them with something that works
