Another Amp question
Hey.
I have another question about an amplifier installation. I recently added a complete sound system to my 2001 F-150 XLT Supercab. which included hooking the amplifier directly to the battery terminal. My dad, a mechanic of 30+ years, was looking under my hood a couple days ago and saw the amp power wire hooked to the battery terminal (factory terminal, have not replaced it.) and he flipped about it. Said that the computer in the truck could read the amp as a drain on the battery, and give false codes, or at worse, blow the computer. he said instead I need to go behind the fuse panel to a wireing harness and junction?? and hook up from there. I honestly think he is over reacting. My father is a great mechanic, but has not done amp installations before. But anyways, does anyone know if there is any truth in this at all?? or if there can be any bad side to hooking up to the battery terminal. and if so, how do you do it another way?? thanks

Your amp must be connected to the positive battery terminal through a fused cable of the proper size. That's how the amp is supplied enough current to operate. An amp is NOT a stand alone component that just needs to be connected to a hot 12V source. It needs current from the charging system. While your engine is running the amp will be supplied current by your alternator, so there will be no drain on the battery, unless the alternator is faulty. If you do a lot, and I mean A LOT, of listening with the engine off, you could encounter trouble at some point. But it will more than likely be battery related. I don't see how it can cause a problem with the computer. In a truck as new as yours, I doubt there is any reason an aftermarket amp will ever cause any problems if it is connected correctly. I would think you're more likely to have trouble if amp is NOT connected correctly.
