This is my 2001 z24 cavalier with a 2.4 twin cam engine. I bought this car all stock nothing at all done to it. But since then i have added a few thing like, 2 12's audiobahn subs in a bandpass box it bumps but want 2 15 kicer L5's but not yet it has a 1600 watt soundstorm amp a 4 gauge wire kit. with tweeters then i have pioneer door speakes i have 2 ways in front 4x6 and 3 way 6x9 in back i still have stock deck cause i want limo tint before i get a deck. Then for the engine i added a AEM air intake made it sound mean then put a dual flowmaster 40 series on with tip now it sound like a beast i have also took off all the ugly decales so every one always ask what kind of car it is and thats it for now. "HAVE PICS SOON"
