not for an amp (I already have amp and audio all wired up, that was first thing i done to the car), but possibility in the future a small 100X2 or 200X2 amp for some components if the head unit channels ever go out.
Basically this mod has no real purpose, it has the future in mind, adaptability and expandability. I would call this my power distribution box, a 8 Gauge wire brings power straight from the battery.
In mach up stage you can see I had a fuse on the very top, this has been replaced by a circuit breaker.
The setup consist of 3 relays, 3 20 amp auto reset circuit breakers, 1 30 amp auto reset breaker, and 2 4 terminal blocks.
The relays control the power for: ACC power, Dome light power, and Parking light power.
As in if I add accessories to the car and want them to be powered by those sources, not as in its replacing power for those devices.
So the fourth terminal is for constant power, it gets the 30A circuit breaker.
if you see the cooper and silver stud in the middle of the relay and the terminal block that's the circuit breaker.
I also ran 4 12 gauge wires to the back, and it has just a terminal block in the back so power will be there also if adding devices.
