Yes,

It will handle up to 10 Amps- that one I listed

Remember that the relay is going to pull a small amount of current to let it activate the relay and let the large current through. That small current may STILL be too much for the remote on the HU.
Notice on the relay that Ryan listed, there is a rating of 12VDC and 30mA. This means the coil in the relay can handle up to 12VDC and it will pull 30mA as its trigger current.

Edit: Here's a basic SPST (Single Pole, Single Throw) relay. http://www.jag-lovers.org/lumps/tech/basics/relays.htm

Yes,

and that larger BOSCH type relay pulls around 200 mA I believe, which maxes out some head units.

Check that out, basicly says everything Ive said and known for some time

the bosch style relays pull only 130-150ma. you can use those.

a bosch relay isn't going to damage a head unit if it's wired properly.
30mA is nowhere close to the 200-250mA capability of most head units.

What do you mean by wired properly, specifically?

just what it says. if you install it the way it's meant to be wired and don't screw something up, shorting out the trigger circuit, the relay will be fine, and you won't damage anything.
the entire point of using the relay is so you don't overdraw the trigger circuit in the head unit.

The ghetto way of doing this is just putting a wire from the battery to the amps with one switch and fuse in the middle. Whether I should've mentioned that or not is debatable. Putting in a relay is more professional, but if you like switches all over your dash, then have at it.
