Ok. Can I use speaker wire though to extend the 12V and ground? The one on the converter is very short. And yes my amp does have that output but my converter comes with a bass **** that I can run to the front of the car, so id rather use that

 

Finally got this done today! Thank you for the write up, was very helpful, as well as everyone who had advice. Car sounds so much better with subs now

 

Good job bro, make a vid let us hear the bass lollololollol \__/ \__/
