I am installing a sound system in the boat and have multiple questions. Any help is appreciated.
I have run the power and ground under the dash. Since the boat is all fiberglass, my only option for a ground is the battery, making my ground wire 10' or so. What problems could this present?
I have ACC power as my remote into the back of my head unit. Once I touched an amp remote onto that same ACC wire, the head unit died. I assumed it was attempting to draw too much power from that line and failed. Thus, I am running another power line and using that ACC as my switch to my relay. I tried using a solenoid starter at first because the guy at autozone said thats what I needed. It did not work and I will be trying the bosch relay after work. I am using an 8 gauge power line without a fuse. Is this okay to run 4 remote wires? Wont all these remote lines then read around 12 volts? Is this an issue since remote wires are usually 5 volts (I believe)? If it is an issue, how do I lessen the voltage?
For test purposes, I stuck the remote wires from 3 amps and the head unit into the distribution block. At first, this blew the fuse in my 4 gauge power line. When I replaced the fuse and forgot to remove the remote lines, instead of blowing the fuse again, it fried my rockford amp (fuseless amp). Why didnt it just blow the fuse again in the power line? Also, why didn't it blow the fuses in my other amps or my head unit?
