So for people interested I installed my old interior neon tubes that I got from Autozone. I have two wired into the cigarette lighter circuit so when I turn the key the lights come on and then I have two in the trunk that pulsate with the subs perfectly. If you wire in the tubes with the subs when the amp pushes current to the subs it also turns on the neon. Perfect and simple modification. I'll post a video later.
