The posts in this forum helped me a great deal when upgrading the audio in my 2018 CX-5 (non-Bose) so I thought I'd return the favour and write about some of the issues I encountered which I couldn't find much information on. Hopefully my experiences will be of use to someone else.
I'll try...
I have a 2014 CX5 touring and just needed to know the most effective spots to add noise reduction. I have 36 sq.ft. of Noico (like dynamat) and 2 spray cans of Boom Mat.
Components include:
(1) RF shallow 12" Sub (400 rms) :D
Polk dB 351, 651 and 6501
Still waiting on the LC2 loc to arrive...
