Doesn't look like your soldering iron was hot enough...you don't have good solder flow at all. Those 2 surface mount resistors @ the bottom right-hand corner look like ass compared to the rest of them. Bad solder joints still spell problems. Try re-soldering those through-hole connections again and get it to flow evenly through the board to the other side so you know you have a good joint.
Sorry, all I do is work with electronics all day, so I know a little bit about this crap. I looked at your other thread and it doesn't look like any of the components burned up.....When I blew up my amp one of the IC's had fried (the black rectangles with multiple legs extending outwards @ the sides of the board) Try checking the ones that are covered up. The problem with electronics is it's much cheaper to replace than repair in most cases. Repairing stuff like this is easy if you know what to look for. Repairing this board would be easy if you had a good magnifying lamp, a schematic, and a meter to check the voltage at various points on the board ensuring the drops from the resistors are correct or if you're even getting power at all.
TL;DR It's easier to buy a new amp for most as opposed to trying to find the problem and rectifying it unless you enjoy that kind of shit and know how to read a board schematic and know how to measure voltage, current, resistance, etc.
In those two pictures I only soldered the 4 points that make a square in the middle (the ones that were obviously cracked in the first pic). My buddy is an electrical engineer and lives semi local so if anything I would have him work on it but im pretty much over it. The deeper I looked the more shitty cracked solder points I found. Not to mention I am fairly certain the thing got fucked up from the joint constantly getting a connection and then not. As I posted in earlier I did notice the amp was randomly turning itself off the last month or so. I am going to chalk it up as a loss and move on. Thanks for the good reply though.

Badass thanks man. I dont plan on upgrading subs in the near future so I will just grab this.
