I am looking to install a completely new sound system in my 2009 platinum. I know for sure that im going with Boston components in my doors so I am mostly looking for some ideas mainly with sub boxes, sub sizes, and how many subs. Post your pics of your systems and let me know what it roughly cost if you dont find. Also im keeping the stock headunit (navi w/ sync) has anyone put a JL Cleansweep or an LC6 ??? Thanks

 

that sounds like a fun project. there is a lot of good info in the sound system section of the forum. here is a link:

hope you find what you are looking for!
