Welcome!
What you're holding in your hands is no ordinary
owner's manual. We've tried to make the instructions
in this book clear and easy to follow.
For your Jensen amplifier to work right, it must be
installed correctly. This manual will show you how to
install your new amplifier like a pro. It's a good idea to
read all of these instructions before you begin the
installation. Most installations are straightforward and
can be handled by a do-it-yourselfer with the right
tools, patience, and the ability to follow instructions.
But, do-it-yourself installation isn't for everyone. If you
still don't feel confident after reading this book,
consider turning the installation job over to someone
better suited to it.
Warranty Service
If your Jensen amplifier should ever require service,
you will need to have the original dated receipt. If you
ever need to return the unit for any reason, always
include the receipt with the product.
