Yes you will have to cut the air box that sits behind the hvac controls out to give the DD enough depth. The kit should come with a template for the cutout.

Thanks for the info. Hopefully the shop I'm taking it to won't charge too much.

Will the cutting affect the air flow of my central vents much? It gets to hot down here to lose my a/c flow.

I never noticed much effect. Just have to make sure to get the hole you cut out covered good and tight then nothing should be causing a decrease in the airflow.

It's not a difficult task at all. If you get the Janus kit, it includes the parts to take care of the heat/ventilation arm relocation. If you read up on all the DIY's you'll get a better understanding of what's required to do the installation. The biggest fear everyone has is cutting up the plastic with a dremel to make room for the DD, but that's no big deal. ONce you make your first cut, you'll get over that initial fear. If you DIY, it'll take 3-4 hours tops. The instructions provided by Janus Design are very accurate and easy to follow.

If you have some dynamat/sound deadening laying around, you can use that to seal up any spaces you have from cutting the plastic airbox.

Thanks for the replies, I'm feeling much better about doing this now. I'll post up pics of the final product once it's completed!
