Play you iPod in your car without a FM modulator!

For ages I've been trying to get my iPod to play in my car, but my head unit doesn't have an AUX plug and I find FM modulators to be of poor quality. As a solutions I desided to go straight to the source. I fed my iPod line directly into my car amp.

THIS WILL ONLY WORK IF YOU HAVE AN EXTERNAL AMP!
It will also only play through the speakers connected to your amp.

This is a very simple solution to a problem many people have. To accomodate both my iPod and HU I have built a switch box to control the source. It's very simple! All you need is a handful of parts, a soldering iron and a DMM.

(Do this at your own risk...if something goes wrong you may damage your amp, iPod or HU)

Step 1 Parts and tools

The parts list is short! All you need for the switch box is:

6x RC sockets
1x 4 pole switch
A small box to house it in
Some good quality wire

Tools:
Side cutters
Wire strippers
Soldering iron
A Multimeter (to check continuity)
Patience!

ya i know, could have left the gnd wires off the switch and just tied them together but i did it to add some isolation to the system.

 You don't need to switch the - ("gnd") just use a spdt switch and wire up the +'s to the switch and tie all the -'s together. great little instructable!

Very cool. This would also be good if your HU does have an aux input but you have multiple devices.

for sure man...it could work for anything where you have more sources than inputs
