Checked the rear speaker wiring again yesterday. They are connected to the rear speaker level outs of the HU.
I managed to squeeze a bit more 'volume' out of the rears by setting the HPF off. Now a comfortable level of rear spkr sound arrives at 1/2 volume, as oppposed to 2/3 earlier. But it's still weak at 1/3 volume.
A query here. Does the HPF setting on the HU have an effect on both A) the speaker level output and B) the RCA outs?
A fallout of checking the wiring - all the krrr/hsss/FM sounds seem to have vanished. Wonder for how long !
The 'bip' sound, when volume hits 0, isn't an Illusion

. It is happening still for the amped channels - fronts and sub.
