My car has no stereo

Like none at all. The space where you normally find stereo knobs and whatnot is taken up by a reversing camera display. Uh, problem: the only time I ever want to listen to music is while driving so I use my iphone se to play music, but the speakers really aren't good enough. What I was thinking of doing is getting a set of portable speakers to plug into my iphone and play music through those. What do you think?

Today I was cruising down this country road and opened the window to take in the rustic smells and I couldn't hear shit. I really need some speakers or a car stereo or something.....
