Is it possible to install subwoofers with the stock OEM navi unit? I read awhile back you couldn't but maybe times have changed. I'm looking to do something new to my car, I'm getting bored with it.

By "OEM navi" I will assume you have the bose system. I tapped the line level to the bose powered sub in the rear deck for my signal to my sub amp. You just need a power line from the battery to the trunk, which is not too hard. I am very satisfied with the Bose system with aftermarket powered sub.

actually if you search around the audio sub-forum here you should be able to find some threads that were posted on how to install it.

Links would be nice. I've been googling but not finding a good write up of any kind.

i also heard that u would have to remove the rear sub if ur gonna install a sub, due to too much pressure!?? anyone know if this is true??

I didn't. If it concerns you, just unplug the harness to the Bose powered sub--the driver would probably act like a passive radiator. When you add a powered sub, I don't think the Bose is giving you too much unless it adds some midbass.

hmm idk maybe i'll just keep it, if it goes bad i'll disconnect it!

This is probably the best link:

i'd also look on myG37 since the installation would be nearly identical.

I have subs in the trunk (signal coming from the rear stock sub) and the rear deck sub is still connected. It might as well not be though. Even when I didn't have 12's out back, I had disconnected the rear sub because it was rattling like a ****. I could barely tell the difference. Seems the ones in the door do all the work. Now its reconnected and either it stopped rattling or I just cant hear it cause I have REAL bass coming fromthe trunk.

I was real excited when I found out that I was getting a car with stock subs... and then sadly disappointed when I heard them. Not terrible, but when you have 3 10s in a car, you should be putting out some real thump.

if its possible maybei'll just try to take the rear sub out to allow more air flow!
