Piecing out and building your home theater is the tough part, and while you can stop there, you might not be satisfied with how everything sounds. The good news is that it might not actually be your speakers or receiver that are giving you trouble. It might just be a matter of switching around some settings to fix some problems you overlooked.
In my experience, speakers are almost never an issue, so if you check for some loose wires and find none, there are still some fixes you can make. Most of these fixes require a bit of technical know-how to even know they could be a problem, but if you manage to put together an entire home theater, then I don't think that'll be an issue for you. In fact, some of these fixes might be something you'll be kicking yourself for missing. If you follow these steps, your home theater will sound much better than before. The only thing you have to be afraid of is your neighbors coming over and telling you that you're being too loud.
