When you connect a car amplifier to a 12 inch subwoofer, in order for it to produce sound it needs some source of music to be provided to it. Then the amplifier can take ownership of the input signal and transform it into a more powerful stronger signal so then the subwoofer can play bass. Now if you are keeping the factory radio or its a very standard plain basic aftermarket headunit in most cases you will not have any kind of sub out for the preamp output. This can be a problem but thanks to clever technology you can converter the signals coming from the speaker wires using a cheap little converter box. This can be picked up from placed like Ebay or Amazon for under ten pounds. Its easy to wire and doesn't require and additional equalizers or processors even no external power is required. It can take around 10 minutes to fit and install into the car stereo with no sub out.
1) Remove the car stereo from the din slot.
2) Look at the back connections for the rear speaker wires.
3) Disconnect them from the wires that are going into the rear speakers installed into your car.
4) On the speaker to rca converter box you will see two input speaker wire terminals or wires on the box. Insert each speaker wires that you have just disconnected from the CD players wiring harness into the left and right to their own dedicated inputs on the box.
5) Now all you need to do is connect RCA cable into the converter box outputs and plug the other end into the RCA OUTPUTS on the car amp. This will then feed the signal from the car stereo which is being sent down the rear speaker channels and into the amplifier so that you subwoofer can now work successfully.
