Does it sound bad when it gets amplified subwoofers?Front
Same here. Phone calls are fine.No idea. I have a fully active front and sub and cannot complain.
^This. Do this.If doing High level to the amps/DSP use the front channels. As far as i know the rears in the 6-speaker configuration have some kind of bass roll-off.
Still it would be better to reprogram the ACM to variable line level and defeat the stock EQ, too.
This way both front and rear channels from the radio will carry full range signals.
