Hi Folks,

I have a question about connecting a Class-D amp from Connex Electronic to the amp and speaker.

- I see that the Cxd500 inputs have +In, -In and two GND pins.
How do these get connected to preamp output from receiver? I only have a + and - coming from pre-amp. Do these go to +In and -In? Or +In and Gnd of amp?

Similarly,
- The CXD500 outputs have the +vcc, -vcc and two grounds.
How do these get connected to speaker terminals? Does the +Vcc and -VCC go to speaker + and -?

btw, this is being used in a subwoofer.

Regards
Ajay
