Hey guys I have 2011 g37 I wa jj t to setup a bass box with an amp how can I go about doing this with out having to do a hole setup change, I wanna keep my bosse system just want to add a bit more bass

 

Lots of threads available regarding sub/amp additions. Search should bring up quite a few hits along with wire taps for signal and amp turn on. I'll be going off of the rear output since the Bose system seems to tune down the sub output at higher volumes. But that's just what I'll be doing. Good luck. Post pics.
