I am going to put 2- 10'' subs in my '99 f-150 supercab. I am going to leave the factory cd player in and hook the amp and all up to that. I have been told that i will need to buy some wire connectors and an loc. Im just wondering where i can get this and what exactly will i need, and also how much it will cost me. Any help would be appreciated.

 

Well not sure what "wire connector" is supposed to be, but all you need is a Line out Converter (LOC) They convernt the high level output from the speakers into low level(RCA Type)

You can get them at almost any audio store for 10-20 bucks

 

Any car audio place should have a loc... Even best buy sells them
