Question Rx-v373-NO SUB.


Novice Member
Hooked up HDMI via ACR
All speakers set to small 100hz
Sub trim - 0
Sub: use
Phz: normal
Running RCA TO Speaker wire to sub(non powered sub)

Problem: no sub sound, no test tone, no nothing....
Sub works when connected to R/L front.
No sound from other speakers connected to sub connection.

Is there a fuse or something that might have popped, plz help...

Atm I'm running 5.0 with large front xover @200.

RCA subwoofer pre-out socket is low signal output, to be used with powered subs only.
