[Wojtek.Stec]

Hi
Help needed on oh how to connect this subwoofer.
Receiver: active subwoofer with 3.5mm jack input (Creative Inspire P380)
Amp: NAD C 320 - details on the photo attached.
There are passive speakers (2 x ReVox 5oW 4Ohms) already attached to NAD

Pre Out-> 2x RCA Splitter (all male) -> one leg each to Main In


The other splitter legs -> RCA to Aux adapter (All female) -> Aux cable of sufficient length -> Sub:

Thanks for your reply.
I guess I could use this one then:

But what then with these cap connectors that goes from PRE OUT to MAIN IN, just remove both of them and leave MAIN IN empty?

Cap connectors replaced by RCA splitters.

Regarding Main in, read my first message again.

ok
So with this cable:

i go out from one PRE OUT (which one red or white?) and put both its ends into MAIN IN? Is that right? what then?
Im sorry but I cant understand your message.

ok, I think I get it
I need 2 of these:

then black ends (according to this photo) goes to both PRE OUT so the PRE OUT now is spited into 4 outputs, then 2 of them goes to MAIN IN to work as a bridge nad other 2 I need to connect to subwoofer, right?

That's it!

You basically want to tap into the connection between Pre out and Main in to connect your Sub.

This combination of adapters and splitters is how you achieve that.

Btw, the presence of that Pre out->Main in cap connector is really useful as in the future, you could add a miniDSP in there to give your Preamp full room correction + subwoofer integration functionality with proper low/high pass crossover, Dirac, Multi Sub Optimizer, you name it
