[QUOTE="CarAudioAddict, post: 112183, member: 545743"] Thats what the fuses on the map are for. If there is a problem, either with wiring or an internal fault, the fuse on the amplifier should blow. This protects the amplifier from severe damage (assuming severe damage isn't what blew the fuse). n2audio is partially correct in saying that higher priced amps have protection circuits. But these circuits are very limited and are no replacement for fuses. Also it should be noted that even low priced amps (like the 800 watt I saw for $99 NEW) have protection circuits to protect against overheating, overload, and shorts. All in all we can all agree that proper fusing is ESSENTIAL to car audio for safety and to protect your $$$. just a few guidelines for fuses and wiring: 1. Always put a fuse within 10" of your battery. This fuse hould be rated at 10% below the maximum current your wire can carry (or your total amplifier load, whichever is lower). 2. Put a fuse everytime the wire size changes. Follow the same rules as for your primary fuse 3. The wire that comes directly off the battery should be the largest wire in your power system. Never increase a wire's size larger than the wire before it. Example - Main power wire is 6Ga, no wire after this 6Ga should be larger than 6Ga. Most of these guidelines are common sense, but there are many people who don't realize this. [/QUOTE]
