So today i went to the CT auto show and was messing around with the 09 TC when i cranked the stereo, i noticed that it hit a lot harder then my stock system. So i got talking with the lady at the booth and she showed me the sub under the floor in the hatch next to the spare tire.

I have a 2006 what would have to be done to get an 08/09 sub in there (wiring, fitment, etc.). They are all over ebay for a pretty cheap price, around 100 dollars. I just want something stock/cheap and the placement is perfect so it doesn't take up any room.

 

good question. I want to know too!!! I have an 07 and would love to do the same thing.

 

yup me to, dont want to spend alot of money on audio since its not my car lol
just a little more bass, wonder if you can just tap into an existing wire or something?

 

Alright well my boss at work used to work at circuit-city doing this kind of stuff on cars (stereo installs). His concern is that there won't be a proper out on the back of the stock 05-07 stereos. From what i have gathered from pictures is that the stock radio in the 05-07 stereos don't have the same plugs than the upgraded 05-07 one with the color changing display along with the 08-09 head units. So I'm thinking at this point in time that you would need to upgrade your head unit to the 05-07 premium head unit or an 08-09 unit to do it. If you wanted to stay stock like I do.

I'm going to the dealer on friday and i will talk to the guy at the parts counter, he knows me pretty well. Maybe he has some input. If not all try and get a hold of a tech or someone that can answer my question, because like people are saying. The stock system sounds ok but with that OEM sub it sounds a whole lot better and its convenient if it is a stock upgrade with little to know need for rewiring.

 

anyone figure this out yet? i have an 07 tc and want to put an oem stock sub in the trunk. i have a pioneer f90bt head unit. if i get the part is it just plug and play?

 

The factory sub has a round connector that is wired with the bundle of wires for the tail lights. It contains the usual stuff for an amp/sub:

+12v constant (batt)
-12v ground (chassis)
+12v remote amp turn on

LR+

RR+

Your 07 probably doesn't have the harness for the stock sub. You would likely need to wire it yourself. It could certainly be done, but wouldn't be plug and play.
