Connecting an active subwoofer with passive speakers

Thank you, but originally it was meant to work on PC or TV.

I'm back with a little issue.
After buying an RCA/jack cable, I tested it and the subwoofer works quite well but not the speakers.

Hi,

The subwoofer already has a built-in amplifier.
At the back, there are connections for two speakers and two RCA red and white ports.
This is for connecting a turntable or CD player or any other devices with that type of output connection (the amplifier's connections are inputs).

That's the one https://h30434.www3.hp.com

Thank you.

The speakers work, but after the speaker output, I don't know.
Isn't there a way to check?

Hello,

The Kenwood subwoofer provides an alternative for external amplifiers that do not have a pre-amplified subwoofer output; it features a high-level output located at the back of the subwoofer, identifiable by its red and black terminals. There is a pair of input (in) terminals for the amplifier and a pair of output (out) terminals for the left and right speakers.

To operate the Sony speakers, you need to connect an amplifier to the red and black input terminals, as these terminals do not amplify the signal.

Here's a compact, reasonably priced amplifier:

Ok, thank you very much.
But what are the terminals on the enclosure for? Might as well connect directly to the amplifier, right?

Good evening,

Here is a diagram that summarizes sawsix's explanations very well:

When you click on the image, everything is very clear ;-)

Best regards and have a good evening ;-)
