I need a little help with the factory sub setup...
Has anyone ever used this box with a good sub, and how well did it work?
Can I use the speaker wires going to the drivers side rear 4" speaker for the amp input for the sub?
For the amp, can I use the power wire for the (now removed) factory 10 disc changer to power the signal wire to turn the amp on? Or do I have to run a wire all the way to the head unit?
I'm open to any other advice for this project as well.
Thanks!
