So I put in a new deck and am currently hooking up my amp and subs. Everything looks good but my amp's protection mode keeps blinking, its not the audio. I thought it could possibly be my ground so i drilled a new hole under the carpet in my trunk doesnt seem to be the problem either.. I feel like its getting to much power, when I turn the car on my lights inside surge? I have a 40 fuse in the amp not sure what I have in the engine or how to get a bigger or smaller one?? Any ideas here would be greatly appreciated I can't seem to figure this one out by myself. thanks!
