Wiring Trunk Neon

i have 2 pheonix gold octane ZR 10" subwoofers (the ones with blue leds in the center of the cone). The amp also came with 2 8" blue neon rods to sit in the rails on the side of the amp. I've got the amp all wired up, but i'm still working on the lights. Here's what i have/know so far:

1. I have a separate power wire connected directly to the battery to power the relay (i ran it when running the main 4 gauge power wire)

2. I want to have the lights turn on when the amp turns on and/or when the trunk's open (suggestions on when they should turn on would help...what works the best/is the easiest?)

3. I have no idea what size/type fuses to use, i have no idea where to place them

4. I have read the "Connecting Additional Devices to the Remote Turn On Wire" on https://www.the12volt.com/relays/page5.asp, and if i choose to wire it this way, my main problem is the fuses (mentioned above)

Sorry about the long post, any help regarding any of these questions would be really appreciated...thanks in advance

You will need to use diodes, for instance when you turn on your amp it will trigger the neons on, but if you dont use a diode the current will flow backwards to the truck light and power it too.  The diode will allow power to only flow one way.
