New speakers for 2013 Access Cab Sport

Got in my truck today to find out that I had blown my stock driver's door speaker and only the passenger works. Put the fade to the back and silence, so I have one working speaker in my truck now. I don't know if the tweeters in the doors have any sound, it didn't sound like it...
I like to listen to loud music, mostly reggae/rock, not so much rap, so not as much bass. I even had the Bass level just below medium setting. But even at the highest volume level of 62, it's still not as loud as my 08 RAV4 Limited JBL system with a subwoofer...
I also don't have a working horn (broken clock spring) or any headlights (spec d design is garbage with no light output) but the engine is solid, so everything else can be fixed... Plus, it's paid off so I can spend a little money!
What's a good speaker setup without replacing the head unit (not just yet)...
I see posts from 2007/08 but I'm sure there's newer and better speakers available!
