What is the easiest way to install subwoofer in the trunk ? I was hoping to take signal from rear speakers via adapter
, use REM from CD changer and thats about it. I can not see how can I get to the rear speakers from the trunk ?
You need to tap the underseat woofers for bass... there is no bass from your rear speakers in the base system.
