I've been reading quite alot recently because I really want to add a subwoofer for some extra bass. Since the door speakers can't quite reach all of the lows.
Now ofcourse there is no RCA output on my headunit.
I've read a few different solutions:
1. Hi-Low converter on front...
Hey guys... I just replaced the headunit in my 2015 and I'm moving to the speakers next. The only thing I can't seem to find online is information on whether or not an extra battery is needed or recommended. Can any of you shed light for me?
