I'm a guy who don't know anything about radios or speakers, oh and new here. I have a 99 Saturn sl2 car that I drive for work. I had a stock stero and one stock speaker and three boss chaos ch6530 no clue if there low end I'm guessing yes. What I have done is receantly went to the local junkyard and found a Sony gt320 stereo and two mtx road thunders pulled stock stereo and the one stock and one boss out of rear put mtx in a radio. The sound I think is about even or worse than before. Is the wiring to thin do i need an amp to run these. I'm not huge on bass but some would be nice. Should I scrap these speakers and find more the junkyard always has stuff cheap. Oh and the front speakers never really were loud at all. Sorry about the ramble anyone help or little info be great. Ps in laman terms
