I bought a durabrand ht-400 from a guy and i think everything was there, but i don't get how to hook up the wires because it has sections like subwoofer,left speaker,center speaker and etc.But on like the subwoofer it has blue,black,green and colors like that but those colors arent all under subwoofer so do i put them under the other sections.
Unless someone here has that particular HTiB, you're not likely to get much help, as blue, black, green, etc. don't mean anything to us.
I would try to find the manual for this HTiB, if it wasn't included. Typically, you only need to run one cable to your sub (marked "LFE in", "bypass crossover", etc.).
I should also mention that HTiB's sometimes have a special way of connecting speakers. Sometimes all speakers need to be connected to the sub, so you really need to get ahold of the manual if the connections are not clearly labeled.
