[QUOTE="i2ain2thunder, post: 7592054, member: 631331"] more notes and tips: Ground connections are very important to do properly. Make sure all grounds are very secure and directly contacting a solid metal surface, that means sanding paint away. Many issues with electrical setups stem from poor grounding at any one spot in the circuit. Wire selection is important,OFC=Oxygen free copper: Highest quality copper, CCA=Copper Clad Aluminum: most wire is this, this was invented as a cheap effective alternative to pure copper, it is very effective and generally a lot cheaper than pure copper. Size does matter with wire, the thicker the actual copper area the better, many companies claim 4 gauge or 0 gauge wire, but just fill the space with the rubber surround, ends up being more surround rubber than actual copper strands look out for this! Fuse rating, generally people misconstrue fusing wire as a means to protect the equipment. Fusing is actually meant to prevent wire fires from extreme power surges/heat. However it isn't exactly unpractical to fuse wire close to the fuse ratings on your amplifiers as it will add some extra protection for them on top of their own protection and fuse circuitry. Always fuse any power run, I.E. fuse alternator to batt + terminal for Big 3, fuse Power leads from Battery 1 to Battery 2 and so on, fuse power lead from Battery to Amplifier. Batteries: make sure "resting voltage" (voltage reading while vehicle is off) is at or very close to 13.7 this is a sign of a good battery, look for any bulges in the casing as that is a sign of a battery gone bad. Any time you are connecting multiple batteries, make sure their resting voltage is a match otherwise problems can stem from what we call parasitic draining, remember current always flows from highest voltage to lowest, meaning if 2 batteries are connected and have differing resting voltage IE. ones is good 13.7 the other is going bad 12.4 the lower voltage battery will constantly drain from the 13.7 battery shortening the life of the good battery.
