So I want to upgrade my 1993 Honda Accord's stereo but I am on a very limited budget. I found a pioneer head unit on ebay for 60$ that I am looking to purchase. Im wondering will just a head unit make my stereo sound significantly better? Also I looked at the speakers that are in the car the other day and they are not the normal crappy quality stock speakers with the cardboard cone. They are actually Pioneers that seem pretty nice. Thats why I am reluctant on buying speakers too because I feel like the only reason my stereo is not sounding that great is because of the head unit. Thanks in advance for any help
