Home Speaker Asylum

General speaker questions for audio and home theater.

Are your main speakers already hooked up to the NAD 3020??




If so, then the only way you can hook up a subwoofer to the system is to obtain an outside crossover and another amplifier(if the sub does not have its own amplifier).

You would first remove the U shaped connectors from the back of the NAD 3020 that connect the RCA jacks labelled Pre Out and Lab In.

You would then run RCA cables from the Pre Out on the back of the NAD 3020 to the external crossover. Next, run RCA cables to your sub amp from the crossover output. From the sub amp, run speaker wires to your sub. If your sub is self powered, then you would just run the crossover output RCA cables directly to your sub.

You would then run another set of RCA cables from the other output of the crossover to the Lab Input on your NAD 3020. That's it.

If you are trying to use the NAD 3020 as your sub amp, then disregard everything written above.
