stream 1 audio L/R (fixed), and another two pins carry stream 2 audio L/R (fixed) – (there is another pair of pins that carry variable stream 2 audio that will be discussed later). Every Bose link expansion product has 2 inputs to accommodate each stream, and the remote control tells the device which stream to listen to. the dedicated sub output on your amplifier or processor. If a sub out is not available then you can use a spare set of pre-amp outputs. If you only have a single sub woofer output socket on your equipment, then connect up using one of the pairs of leads (red to red). In this instance use the (Mono) input on your XLS200 sub.
The LM386 takes anywhere from 4-12 volts of DC voltage to operate. The sound signal to be amplified are placed on terminals 2 and 3. The amplified sound signal then exits through terminal 5. After a few capacitors and a resistor to filter out unwanted noise that may be on this signal, we connect the speakers to play out the amplified sound. do like this man says, wire each sub to 2ohms, you do this by paralleling them. that means wiring each voice coil together. you take the positive on one side to the positive to the other side, and the negative from one side to the negative to the other side, then take a positive from one voice coil and a negative from the other voice coil and run that to the amp. this takes your dual 4ohm voice coils and makes them one 2 ohm coil. you will get 1600 watts rms per amp this way. now getting ...
