Hey everybody! I had just recently got my first monte carlo a 2001 ls! i love it! enough said. But my question is about the stock amp it came with. Can i install new speakers to the existing amp and will a subwoofer from another amp mess it up in anyway? i recently installed my first cd player and that was fun everything turned out well and am about ot put new headlight lamps and and taillights with HID and led taillights this spring! and thats all easy enough but its just the stereo that gets me.Any help with this stock amp and new stereo installation will be a great help!
