1997 3000gt Base speaker newb question. - 3000GT/Stealth ...

Hi there, I've been browsing the forums a lot lately, just to get some work done for the car that i've been putting off for a long time. My speaker. ... want a small upgrade that might lead to less thumps. I do have a pioneer cd receiver that came with the car when i bought it used but i don't know its power output. I'll look that up and post it on here later on. Sorry, i don't know much about car audio, just looking for suggestions, any help would be much appreciated. ...
