Need help!

[smithmr20]

I have a wire for a car audio accessory, now currently the product being installed is pushing 300mA and I need to make some sort of board (or something!) to convert that 300mA to 1amp. Is there a quick easy way of doing this?

Thanks..

Use a simple transformer that will lower your voltage.

You need a relay. Connect the coil to the 300 mA output and use the relay contacts to switch the 1A load.

It is a car audio enviroment, so it's DC and a transformer wont work there

Ok, great! Now, what type of relay would I use for this setup?

Sorry this is not my field, I greatly appreciate the help guys.

Thanks again.

You need a relay with a 12 V DC coil, and with contacts rated for at least 1 A at 12 VDC.

There are many styles of relays you may use, from small printed circuit mounted ones to the ones used to switch extra headlights, horns, etc.

Just visit your local auto parts or electronics parts store and ask for 12 V DC coil relays, and check the specs of the diferent models they offer.
