Ahh ok I don't want no max power thing going off in my boot I just want a slimline sub to add a little bass on take it off the door speakers, wanted it for original head unit people have been doing it from rear speakers but I ain't got them being a 2011
I have a big sub in my trunk, but I have rear speakers. A good audio company can help you connect the Hi-Low converter to somewhere maybe behind the stereo, and it's really worth to hire a proffessional to do it.
