I want to put 5 1/4 speakers in the doors of my S4 like the S5. What is the best way to do this?

 

Some S4s came with a factory door speaker just above the arm rest. Most did not but every door I've seen has the factory speaker hole on the door itself. Theres a bracket that bolts up to the door that lets you put 6 1/2" speakers there. Post a want ad on the for sale section and if you're lucky, someone will have the door panels with speaker grill and the speaker bracket.

Your other option is to cut your door panel and cut the metal on the door to fit the speaker of your choice. This will probably be the best way to do it since locating the door panels with the speaker grill and brackets will take a while.

 

Thanks.
