Car Amp Ground Wire Melted | Electrical Wiring

Think of the ground wire or cable as your electrical system s foundation the bridge over which all electrical flow must tread. Work on it long enough with the doors and hood open and the voltage drops creating an amp spike when they turn the vehicle on.

I would run a peice of 4 guage from the distro to the chassi ground and sand off any paint.

Car amp ground wire melted. I have the same car make sure every time u fold ur seats up it doesnt fuck with the ground wire if u have shitty wire it might even cut it. My problem was i was only running 8 gauge wire and i had a terrible ground connection. The amp has dual grounds so i have 2 8 gauge wires running from the amp to a distribution block which has a single 8 gauge wire to the chassis.

Yeah the ground is to small. Each amp will require at least that size for its ground and you may as well match that for the short power wire from the amp to the distribution block. Drop down to 4 gauge atleast and get a solid ground.

As for the rest of the power and ground wiring i d use what each amplifier s specs call for in this case 8 gauge wire all around. My power wire continued to melt. Diy car repair with scotty kilmer an auto mechanic for the last 45.

Often bad ground wires cause weird electrical problems like making the parking lights come on when you step on the brakes. Make sure you have a good solid ground and a thick enough gauge wire.

Fuse should have popped if the proper rating if too large the wire melts. The ground to my car stereo amp melted yesterday and was obviously very hot what causes this. Replace fuse holder and melted sections of wire possibly the whole power wire.

Keeping in mind the bright light wire hot wire is on each relay s switch side. The only one that melted was the stock bright bulb ground wire. Your car s ground wire also known as a ground cable or ground strap is perhaps the single most important wire in its entire electrical system.

If your amp has a high resistance ground this will almost assuredly heat your wire. For a 12 foot install 4 gauge wire is good. A bad ground connection will ruin your electrical system s day which.

You can always take a dmm and measure the resistance of your ground points to check this. Also you may want to consider swapping that wire now if it was getting that hot you may have started to melt away the outer jacket. I had this happen to me on my old amp.

So i brought one 10 guage tapped off the hot wire with solder up and then soldered 10 14 guage wires off that to run to all the relyas so the bright light power would switch them all on.
