No. Stock HU only. However, you can connect a powered speaker to the output of the navigation to hear the Nav audio when using an aftermarket HU. Do a search. It's been discussed before.

 

where did u get that box? custom?

 

That box is made by 4080. Do a search for 4080 subwoofer box. You'll find it. He sells them for around $300. I have one as well.

 

On the 4080.. where is the metal bracket at the top of the box? Does it go inside the trunk? I have seen it out and Ive seen some with out it exposed.

 

The metal bracket goes under the weather stripping. You need to lift up the weather stripping, press the box in place so the metal bracket is flush with the trunk lip and push the weather stripping back down over the lip/bracket to hold it in place.

 

hey bluerex how did u ground the amps? I need some hint for my upgrade install
