First post on this forum. Great info!

Just got the old lady a 06 Escalade.
Stock Bose system, no navigation.

Question is can I add the sub in the rear panel and is the wiring and or amp connections already there?

Has the 2 tweeters on the window colunms and mains in both front and rear door panels.

Just want a little more bump

Thanks in advance.
