is it possible to conect the amp after the sub through the RCA line out of the sub?

Hello there!

Is this possible without frying anything?

I have a small Denon receiver that I am using as a preamp. This is connected to a NAD amp. The problem is that I do not have full control over the denon because the pre out are only for zone 2 and 3 (I can only operate it via the remote). So all this conection question is to gain full control of the system with my little receiver.

Here is the question: Can I, after connecting my denon to the sub (DSWpro440) via speaker cable, get the audio signal through the RCA output in the sub then send it to the amp and then from the amp to the speakers?

A simpler layout

Receiver (main speaker out) to (speaker in) subwoofer  subwoofer (RCA line out) to amp to speakers

Any help will be appreciated,
Thanks.

    Hello Gat,
    Good question! I'm afraid the speaker level input won't provide a suitable line level on the sub, only an incoming line level would. You might be able to use a speaker level to line level converter to do what you want. The Carver company used to (and still might) make a connection box that allowed people to feed a speaker level signal into a power amp. There might be other companies making something similar so maybe check with your local audio shops.
    Regards, Ken

    Welcome to Club Polk, gatucar!

    What Ken's talking about, I think, is this little black box (about 2" x 2" x 2-3/4") unit from Carver that essentially turns (attenuates) your speaker outs from your receiver into preouts. It has speaker wire inputs and RCA outs. The one I have is called a Carver Wide Band Z Coupler, Model Z-1, that I bought back around 1990 and it works great. I have it hooked up between an old Onkyo receiver that puts out 40 or 45 WPC and a Kenwood power amp with 100 WPC. In over 20 years of use, I've never had a hiccup from it.

    Hope that helps.

    Kenneth, Teekay;
    Thanks a lot for the info. This was not a common question and I am glad there are alternatives to solve it!
    I will try to get myself one of these adaptors. I live in C. Rica and it is not simple to get gear over here. Teekey, do you expect a drop in quality after this kind of connection?
    Regards

    No drop in quality of signal at all. I've used this in a setup with a pair of Monitor 10Bs for over 20 years and the sound has always been very nice, crystal clear.
