Do I need to have a stereo receiver with outputs for a subwoofer in order to use one (I have an older model)?
Answers: If you have a self-powered subwoofer, then all you need to do is connect your powered sub to the OUTPUT RCA terminals of your receiver. To connect the Left and Right OUT RCA terminals of your receiver to the MONO RCA terminal of your subwoofer, get an RCA Y connector/adapter from your local Radio Shack or other consumer electronics store that allows you to connect a pair of interconnect audio cables w/RCAs to a single interconnect cable w/RCAs.
If you have a passive (i.e. non-powered) subwoofer and you have a second set of speaker terminals on the back of your receiver (A [main] and B [secondary] speakers), you can bridge your subwoofer to the B section of your receiver by connecting the plus speaker cable of the sub to the plus of the Right channel and the minus of the sub to the minus of the Left channel on your receiver.
It is not recommended to connect your sub together on the same connectors of your stereo speakers because it may create too much of a load on your receiver and which can cause the amp to overload and blow (which will then cause the need for a costly repair or replacement).
Side note: if you have a passive subwoofer and want to connect it to your stereo receiver, this is not ideal unless your subwoofer cuts out or rolls off at a low top frequency (i.e. 80 Hz or lower) on its own. If not, then your sub may not blend well with your stereo speakers (your sub and stereo speakers should not play the same bass frequencies, otherwise it will muddy up the bass -ideally, you want the sub and the main speakers to roll off at the same frequency thus substituting for a properly designed crossover) and may also affect the stereo imaging by advertising the subs placement location in the room due to the higher frequencies it's playing.
yes for the most part. could splice them into the other speaker wire or cut the end off the subwoofer cable, split the wires, and out them in the wire inputs
not usually _a sub usually has line level imputs for R & L channels In a powered sub. IF your talking about the speaker only then you need to go to radio shack
