Default Adding a subwoofer to a standard headunit?

Can anyone advise me on how to add a small subwoofer to my standard headunit as there are no RCA outputs on the rear to run to an amp.

I don't want to upgrade my headunit because I am boring and like to keep my car standard inside

Any help appreciated

Cheers

Either get an amp that will take an input directly from the rear speaker output as the input or one of these - http://www.ebay.co.uk/itm/Speaker-to...item4154ba0acc

As Jon Says, get one of those adapters. Pretty much the only option without changing the head unit fella

Standard is good, and sleeper surprises everybody. That's what it's about.

The best way is to buy a active sub. Run a live from the battery, negative to a rear seat bolt, audio feed from the rear speakers and the switchable live from the cigarette lighter wiring. I suggest you place a toggle/button switch on the switchable live, so that you can have the sub on or off without messing about with the sub volume adjuster. I works for me.

If you change the speakers you will also notice a great improvement.

Guys thank you very much that's all I need to know. I'll order one of them converters and get a speaker upgrade at the same time. Cheers for help

One other thing with that converter, if I use my rear speaker outputs to power it, how do I then power my rear speakers, do I just add them in too?

The sub and amp are both around 500w rms each, it's s 2 channel amp bridged and the sub is a 10in

It depends on the sub. My one had the RCA input as well as a speaker line in.

When I change the door speakers, I branched off both the rear door speaker connectors and connected them to the sub through the speaker line in.
This enabled me to have the rear speakers and the sub working...
By taking the audio from the rear speakers you'll have to remember that if you fade the rear speakers. This will effect the volume going to the sub as well.

+1. Only I'd call it speaker level inputs, had this same set up, on several leased cars
