Installation Videos & Manuals
We show you how to install a complete car audio system. We install a subwoofer, and amplifier, front speakers, rear speakers, and add sound dampening material on the rear deck and in the front doors.
We show you how to install an amplifier in a vehicle with a factory amplified audio system.
Amplifiers are power hungry devices that are the heart of every car audio system. A power line fuse on your amp is essential because without one you could have a fire if the power wire is accidentally shorted. We show you how to properly wire a fuse at the battery of your vehicle.
We show you how to wire speakers to your amplifier. We show 2 channel, 3 channel, 4 channel and 5 channel connections.
James shows you how to wire your subwoofers in Parallel or Series, explains the difference between Single and Dual Voice Coils, and teaches you how to calculate the impedance of your system!
Confused by what gauge wire to get for your install? Let James show you how to figure it out!

We show you how to set the gains on your amplifiers correctly using an inexpensive oscilloscope. Using the DSO Nano V3, we demonstrate what amplifier clipping looks and sounds like. We then demonstrate how to set your system up the right way and prevent these damaging issues.
