Hi Guys,

I would like to know if its possible to connect one DSP channel to 2 channel Amp via (Y) RCA to run (2x Sub's at 4 ohm)?

The reason I do not want them to be at 1 channel at the Amp cause they will be parallel, which will make them running at 2 ohm.

And I do not want to use 2 channels from the DSP just for the Sub's cause I am going to be using all the other channels...

PS: Please check attachment below

Thanks in advance

Fahad

Oh one more thing, are the sub's going to be at 4 ohm each?
If you connect them each to one channel and run the amp as a stereo load them yes the amp will be seeing a 4 ohm stereo load. You will just be sending it a summed mono signal.

No so, The drop in voltage will be negligible - likely less than 0.3 dB.
RCA inputs to amps are typically 5K to 47K ohm impedance, and DSP outs are likely 600 ohm output impedance or less.
I always appreciate it when I learn something new. It never occurred to me that the amp wouldn't be actually using the voltage on the RCA as much as the voltage is used to simply drive the signal to the amp.

Thanks!:thumbsup:
