hey, im hooking up my freinds system 2marrow..........hey has a Fosgate 1800 watt amp........should i go with 2 guage 1800 watt power wires......or 3400 1/0 guage??....what about hooking it up 2 the stock cd player in his caviler..will a adaptar support that many watts??
Never connect an amp power line to any wire in the car. The only wire you touch is for switched power to turn the amp off an on. For constant power always go to the battery. Unless he plans on putting something real serious in the car you really dont need 0/1 guage 4 will be fine.
huh???? u totally lost me........i no how 2 hook it up....i have a massive system myself.......4 guage wire will be big enough 2 power a 1800 watt amp???
Yea anything over 1000W I'd definately do 2 gauge, anything 1500W or more I'd do 0 gauge. 4 gauge is absolutely not big enough. And yea the HO alternator definately helps with that much amperage.
