[QUOTE="Rwr1311, post: 8492477, member: 668541"] I am planning to install a single SA-12 powered by a Twisted Sounds 1.3kw. I am using the factory head unit. The factory system has a weak sub that I am replacing (car is a 2013 Audi A4 with standard audio system (not B&O)). The amp does not have speaker level inputs, so my plan is to cut the inputs to the factory sub and use a line output converter to connect to my amp.
