Subs not working

Hey fellow audio heads I need some help, long story short I hit a curb and my subs went out. I took my head unit out to look at it and I noticed my control wire was out, I put it back in but smoke came out of my head unit wiring . Looks like the fuse on my unit is blown but I'm not sure because my capacitor still turns on just sporadic when it feels like it wants to cut on. Much help needed, it's a pioneer head unit BTW and Jl audio speakers but can't get sound out of them aka bass
