I was just wondering if there is an easy way to hook up another amp and subs to the stock head unit and be able to use the sub control on an 07 SI?? Im eventually going to change out the head unit but I was just wondering for temporary purposes.

 

Check out 8thcivic.com for a really detailed write up. I did it myself and its not necessarily "easy", but you can do it in a good 2 or 3 hours depending on your skill level.

However, you will need a LOC (line out converter), I used the PAC-SNI 35. If you don't understand any of this, read the DIY before asking anymore questions.

EDIT:

Here I went and found the link for you since the search button owns some people.
