leaky sedan trunk

OK guys what the hell do yall think it coming from. only thing i can think of is the tail light seals. i re-seam sealed all the gaps and under coated the inside of my tunk. but its still getting water inside when it rains. plus the moisture fogs my back window hella bad and i dont want to put another sub in till i fix it so i dont water log it. any other ideas? if not ill just get some seals.
