Honestly, it looks very bad! the U8 IC is clearly shot (probably the components under it as well, in the black charr), it's possible the trace is damaged also. U19 could be damaged as well (or it's just covered in leakage, hard to tell from the pic) And on the 2nd pic (electrolyte capacitors) I don't think that's glue man, they're shot to hell (and would need to be replaced!). Overall, if you have good soldering skills, a decent soldering station, and a hot air station, it's likely fixable (provided you'd source the parts) that said, it'd definitely be a time consuming fix, so consider your options wisely. If you don't have a hot air station, then the repair is not cost-effective (and buying a new speaker set would be best)
