Go look at the AudioControl LC7-i: AudioControl LC7i (Black) 6-channel line output converter with bass restoration — adds aftermarket subs and amps to a factory system at Crutchfield
I plan to use this line out converter (LOC) along with a 4--channel amp (45wpc), connected to my OEM radio, along with new speakers. The LC-7i will allow me to compensate for the OEM radio's factory sound restrictions and add a powered sub, with control over tuning each channel and the sub as well. If that doesn't cut it, then and only then will I add a new head unit. But I think it will work based on some posts and reviews I've read. It's worth looking into. The LC7i has some features the LC2i doesn't.
But I am not 16, so I don't need mind-numbing sound levels, just good, full, well-balanced sound. If you want more, go with the LC8i, which adds two more channels, and run another amp to the rear speakers. This will allow you to have two amp channels available for the tweeters, plus two for the front doors and two for the rear doors, which will require two amps - a four-channel and a two channel - or a single six-channel amp ($$$), plus two channels for subs. I don't need that much.
There are a lot of ways to go, but I think my plan will work for me. Just some more options to look at.
