I am looking at 2 jensen head units and one (200 watt version) says it has :
RCA LINE OUTPUT (1.5V) & SUBWOOFER OUTPUT

The other (180 watt version) says it has:
2 PAIR RCA LINE OUTPUT (3V)

Is this the same thing? Can't I use the second RCA lin output to go to the subwoofer? I got the 180 watt version and I just noticed this now, its the CDH900.

Thanks, Suke

 

It doesn't sound like it is exactly the same thing. Usually when a line out is labeled a sub out it means that the head unit has some sort of gain or x-over control that is dedicated to that out to control the subs performance. You can use a regular line out to go to a sub woofer you will just have to make all adjustments at the amplifier. Hope this helps.

Yeah thanks that cleared things up for me.

 

The dedicated sub out is usually non-fading, where as the one with a front and a back output would change the levels of your sub when you mess with your fader. The 3v outputs are a little nicer too.
