If you exceed the current rating of that line coming out of the headunit, you are going to have problems...I've heard of it happening before, and this is by far the safest way to do it. Just daisy chaining them could work, but is it worth it? I don't think so...
It all depends on the type of amps and the type of headunit. Some heads have a higher rated amp remote then others....I only feel comfortable triggering three devices maximum from one amp remote lead - this is why I suggested a relay.
