I have the stock 04 style CD player that is not Fosgate and does not have the mp3 input. Its black, not part of the dash like some. Can I get an amp and sub and hook into the stock radio or do I need an aftermarket CD player?
If you are asking in regards to the OP, yes a LOC will work. He shoudl buy it from tech12. Comes with instructions and phone support. Mitek reQ or reQ-5. Depending on desired audio pleasure.
If you are asking about something else altogether, quit hijacking and start your own thread.
