[QUOTE="crow, post: 1904693, member: 568415"] First thing I would do is go back to Best Buy and tell them I want my tools back. If you trust them, have them troubleshoot the system. You paid good money for the install and you bought quality gear, they should make it right. According to what I'm reading about the protection on the Alpine, the excessive current may be caused by a short circuit somewhere in your system. This would certainly cause the amp to go into protection. If your going to troubleshoot the system yourself, the first thing to do is disconnect the negative terminal at the battery so you don't risk zapping anything. Check all the wires to be sure they are tightly connected and that there are no areas where bare wire may come in contact with another wire or conductive surface to cause a short. A good way to do this is to start at the top. Trace all the power wiring back to the amp starting at the connection at the battery just to be sure it's a clean run and the fuses are good. Then check the ground to the amp. It should be the same gauge as the power wire and as short a distance from amp to ground as possible. Make sure it is bolted solidly to clean bare metal on the chassis. Some installers will just find the nearest factory bolt and use that. Sometimes they end up with a good ground and sometimes they don't. I like to sand the paint off to bare metal and install a bolt or grounding lug so I know I have good contact. Check all the speaker wiring to the subs. Make sure everything is wired correctly to provide the correct load for the amp and that the wiring is cleanly terminated. If everthing outside looks ok, you may be looking at something internal on the amplifier. [/QUOTE]
