How do you install aftermarket car speakers in a 2004 Hyundai Santa Fe in the front door speakers?
You take your stock ones out and put the new ones in. People usually power aftermarket speakers with an amp which connects to the RCA's in the back of the stereo if your car radio has RCA's. If you don't use an amp for the speakers then you wire them to the wires that were on your stock speakers but there won't really be any difference.
