I currently own a 2003 Acura CLS 3.2 with the stock Bose head unit. I am not looking to replace the head unit as of right now although i have ordered my amp and subs. My concern is, are there any audio outputs in the back of the Bose unit so i can run the necessary RCA’s to my amp? If not how can i install the amp without replacing the Bose unit? Any kind of help would be greatly appreciated Thanks, Bill
I own a 2003 Acura 3.2Tl S , can someone show me where the antenna cable is attached to the stereo unit? I opened the required panels on the driver side and looked. It was not obvious.
Thanks, Sergio
