what speakers to buy?

[Sharky125]

Howdy guys and gals, im new here and i require your knowlege and expertise. My dad just bought me a 94 g20. To my surprise, my rear speakers are blown. Im pretty sure i can take out the rear deck by myself, and installation shouldn't be too bad. I was thinking about buying new speakers for about $50. (i know its not much to work with) i just want something that i can drop in place of the old clarion speakers. I'd rather not cut holes in my car, but i guess i gotta do what i gotta do. And the whole mess with the ohms, i have no clue whats going on. If some one can help, thatd be great. Thanks.
