The neon light draws less current than a crossover (1.9 amperes as opposed to 3.6 amperes) and people jumper crossovers from their amps all the time. Also, how would wiring it to the remote hurt anything? You can wire 6 amps to your remote wire, no problem, so what would it hurt to wire one or two amps and a neon light? When you talk about turn on and constant power circuts, ohm loads aren't an issue. It's like comparing apples to oranges. If you're really that worried about burning up your remote, put a fuse on that *****.... Trust me, it won't hurt a thing.
PS: I don't have neons in my car, but i have my remote wired to a distrobution system to turn on both my amps, my crossover, and my eq. That's way more amperes drawn than simply a neon light and an amplifier.....why hasn't my remote blown yet?
