I have a 2006 Tribeca Limited edition with the subwoofer on the
rear right of the cargo area. I am upgrading to an after market
mono amp and subwoofer. I have the amp hooked up. I ran the
sub signal from the back of the head unit by cutting the exsisting
signal that is connected to the factory sub and reconnecting the signal to my mono amp. I ran the sub signal directly to my speaker level input on
the amp. I started the car and turned on the stereo. Sounds
are coming out of all front and rear speakers, but no sound
from the subwoofer. I have checked everything, even connecting
an external audio source to the mono amp and I was getting the lows
from the sub. So it is not the amp setup. It has to be something
with the sub signal coming out of the head unit. I have exhausted
my search on the internet to find the resolution. Any help you
can provide would be greatly appreciated. The amp is 4 ohm and the
sub is also 4 ohm.

thanks for the reply. I did try the line out converter as you suggested before I posted the thread but it didn't work, I still get no signal. It's weird. I had tried with another amp with sub built in and it work. The other amp with sub is the Sound Ordnance B8PT. I didn't like the bass sound from the B8PT that is why I want to go with a separate mono map and subwoofer. The weekend is coming up. I will try to figure something.

I forgot to ask on my reply. Did you cut off the signal going to the factory sub and reconnect the signal to the line out converter? Also, when you connect to the line out converter, did you combine the two neg and two pos together? The sub signal from the head unit has only one pos and one neg.

Does anybody know what are the 4 wires on this subwoofer? I have a base model and bought one from a Limited in the cargo area....
