QuestionI have a Visonik VB101PK and I don't have the installation guide. I've figured most of it out but I don't know about connecting it to the battery. Can you tell me how to put this amp in my car?
AnswerHi Jake,
Sorry about the delay in answering this question. I wasn't able to find an owner's manual for your amplifier either, but from what I can tell, it's a very small, relatively low-power amplifier.
The power rating of the amplifier will determine the thickness of the wire you need to connect to the battery. In this case, you'll probably want to use a 10-gauge wire. This is the smallest size that's commonly sold in an amplifier wiring kit.
The amp wiring kit will include one main power wire, usually 15-20 feet long. The power wire will include a fuse and fuse holder. In addition, there will be a ground wire; this is normally about 3 feet long, without a fuse. In a typical amp installation, the main power wire is connected to the positive battery terminal, and the fuse holder is placed as close as possible to the battery connection. The ground wire is connected directly to vehicle chassis metal near the amplifier mounting location. It's not necessary to run a ground wire all the way to the battery, because the negative battery terminal is connected to the vehicle chassis. This means that connecting the ground wire securely to a metal point of the body or chassis will work just as well as running a wire back to the negative battery terminal. Usually, I'll make the ground connection by sanding or scraping the paint off a solid point of the vehicle's floor, and connecting the ground wire (through a ring terminal) securely to the floor using a self-tapping screw or a nut and bolt.
The purpose of the fuse at the battery connection is to protect the wire in case of a short circuit. Without a fuse, a pinched or shorted power wire could result in a fire. If you use a 10-gauge power wire, then the fuse at the battery terminal shouldn't be larger than 25 amps. In most cases, you can connect the power wire directly to the battery terminal using an existing nut and bolt, but in some vehicles, you may need to replace the factory battery terminal with a new one designed to let you attach additional wiring.
Hope this helps!
Brian
