wiring neon lights off amp

1. Would there be anything wrong with screwing a new cable under where the power cable connects to the amp, to use for some neon lights? see, i want to hook the neon up to light up the sub, and so the power source is much closer, i'm just thinking about sending a wire up to the centre console to connect up a switch, which would be a lot les work, is there something else i should put in there? 2. Also, i would like to hook up some LED's (not led strip, but single led lights or possibly led cluster bulbs) under the car, to light up the ground, how would i go about securing them so that they won't come off when it rains, but i don't want to cause damage to the car. Also, i'm using 10 lights, should i worry about fade? would it be worth doing a parralel curcuit to try and avoid fade? Thanks for any help you can give me. Paul

hey man i would try it out ive never done it b4 tho let me know if it works.shawn need help

you wont have probs connecting some lights to your amps power wire. you could use a relay to have them turn on when the amp is on
