Alright, so a few years back my stepmom bought me some speakers for my car but they were the wrong size so i just put them away because i didn't feel like returning them. is there a way i can use them to make a form of home theater or a simple "plug and play" stereo for a phone or PC using an aux cord????? my only experience with audio equipment is simply replacing my car speakers with new ones, but im a quick learner and would love for some feedback on how to do this sort of thing if its even possible.
