Hi, I'm Allan Roth, with Cartronics Biscayne, here in Miami, Florida. And today, I'm going to show you how to bridge a car stereo amplifier. The tools we're going to be using are pretty simple, a wire stripper and a Phillips screwdriver. First, we're going to take the wire from our sub woofer, we're going to split it down the middle, separate it a little bit. And we're going to strip off, about half an inch of insulation on both the positive and negative wire. Then, on most amplifiers, you should always consult the owner's manual. But on most amplifiers, to bridge a two-channel amplifier, you're going to use the left positive and right negative. On this Penguin amplifier, that's how it is, that's what we're going to do. But please consult your owner's manual, to make sure you don't do any damage to your amplifier. So, we're going to take the positive woofer wire and connect it to the left positive speaker terminal. We're going to tighten that down real good. Then we're going to take the negative wire and connect that to the right negative speaker terminal. And we're going to tighten that down, real good. And that's all you have to do, there you go. That's how you bridge a car stereo amplifier.
