Best way to connect a subwoofer or subwoofers


Hi, all (especially Paul)!

I’ve been watching the “Ask Paul” videos on YouTube and in two of them, he mentioned that his preferred way to connect a subwoofer in a two-channel system is to use high-level/speaker-level connections from the power amp to the sub, assuming the sub has high-level inputs. My questions:

  1. Assuming your subwoofer has both high-level inputs and outputs, how would you wire in the main speakers? From the power amp as well, or from the sub’s high-level outputs?

  2. If you want to use two (or more) subwoofers in the system, what would be the optimal way to wire them, both for subs with and without high-level outputs (assuming high-level inputs on both, of course)?

Thanks! Love the videos, but Paul didn’t really elaborate on the wiring beyond saying that you should use high-/speaker-level outputs from the power amp. :slight_smile:


  1. The main speakers are wired in the normal way. There just happens to be wires going from the amp to the subwoofer as well.

  2. Wire one sub to the amplifier’s left channel; the second, to the right.


Great, thanks! Simpler than I thought. :slight_smile:

On a somewhat related note, would this also be the recommended way to connect a sub or subs to the Sprout 100 integrated amp, which as I understand only accepts banana plug speaker connectors? It has an RCA subwoofer output.

Thanks again!



I prefer using the high level input of a sub when available so I would go the same way with the Sprout.

But the Sprout has a summed output mono subwoofer out. If you have only one sub with a single channel input this may be the way to go as you will get all bass signals to the sub, regardless if they are on the left or right channel.


This way worked the very best for me. I am not changing this process for my subs. It’s a keeper.


I don’t do it this way. I connect both L and R channel from pre-amp to subwoofer A input, and subwoofer A output to L and R input of subwoofer B. i.e. daisy chain them, so they both receive identical line signals.

And about using high level I/O of subwoofer. To be clear, the power amp is connected to the subwoofer high input, and the subwoofer high output is then connected to the speakers.


subwoofer to speakers is appropriate if you are using a sub’s high pass filter. Otherwise I suggest connecting both the sub and speakers directly to the amp.


I bet it will sound better the I set it up. Well worth the investment. I have tried a few ways. The way I mentioned is similar to the REL sub prefer way. Ask Paul.
