Question regarding factory Sub

[eric_in_tx]

I have a new to me 2006 Expy King Ranch. The factory head unit was replaced with a JVC double din unit. Noticed when I went to the area where sub is located that no sound is coming out of it. The area is present with the hole cut and the color keyed speaker cover in place. Is there a way to wire the factory sub up to the JVC head unit?

I have an '03 EB and it can be done I had a Pioneeer double din installed @ an audio shop and they were able to wire the sub and factory amp to the head unit some how...how they actully did it I have no idea but I'm sure if you find a audio installer they should be able to figure it out...

Thanks for the response. I am 99% sure that there is not a place for that on the adapter wiring. Thinking I am going to have to splice the original sub wire and fit it into the adapter myself to power it up. Crazy thing is the system sounds pretty nice as is. But you can def. tell the bass is short of what it could be. I will be upgrading the speakers little by little. The rig is near perfect inside and out. I do need to get a new piano black B pillar trim for the passenger side though. But if that is all I have wrong on a 7 year old truck with 86,000 miles I will just shut my hole and be happy happy happy.
