Is the sub out on a D3 mono? -Yes, some people do run Stereo subs.
Reason I'm asking is because I'm thinking of buying a used D3 and need it to go to my RF 3sixty.2 which has a single RCA in for the sub. I have a y-adapter, but I've read that Pioneer headunits will blow a fuse if the RCAs are shorted.
Also, has anyone actually measured the output of the RCAs at 1khz 0db?
Thanks for the help.
