How about the position of the level knob on the sub?
No nothing happens. Its as if its not plugged in. That link I,ve put here must be wrong but it seems exactly as what Ive got. Thats why I was chuffed I found that online. Perhaps I,m missing something simple.
You may not get this description, but I,ll try.
1 laptop to sub, connected by mini jack to rca[line inputs rca]
2 this makes sound from sub, "volume" by adjusting crossover dial
3 Take out mini jack/rca cable, not needed as per diagram
4 connect aux input to mini jack in laptop
5 connect amp outputs to speakers, at same terminals wire to subs speaker inputs
6 If this is correct wiring, I get sound from speakers but dead sub
