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.

Installation

Before You Begin Installation

Before you begin, you will need tools, supplies and adapters. It is best to make sure you have everything you need before you start. There is a list of supplies and tools on the next page.

Amplifier Location

Disconnect Battery

Before you begin, always disconnect the battery negative terminal.

–

Important

Allow air circulation around the amplifier.

The XA4150 amplifier’s compact design allows greater flexibility in mounting. It can be mounted under a seat or in the trunk.

When selecting a location, remember that amplifiers generate heat. Select a location where air can circulate around the amplifier. Do not cover the XA4150 with carpets or enclose it behind interior trim panels. Do not mount the amplifier in an inverted or upside down configuration. Every installation will be a bit different based upon vehicle design. Check all locations and placements carefully before making any cuts or connections.

Important

If wiring connections are made wrong, the unit will not operate properly and it could be damaged. Follow the installation instructions carefully, or have the installation handled by an experienced technician.

Professional Tip

Amplifier Installation Kit

Your installation job will be much easier if you purchase an amplifier installation kit. These kits often include low-level RCA cables, extra large power and ground wires, a fuse or circuit breaker and connector for the battery.

Supplies and Tools Needed

Supplies:

•Speaker wire (12 gauge for subwoofers, 16-18 gauge for other speakers)

•Sheet metal type screws for mounting amplifier

•Electrical tape

•Solderless crimp connectors

•1/2' thick plywood or particle board to mount amplifier on

Tools:

•Flat and Phillips screwdrivers

•Wire cutters

•Wire strippers

•Cordless or standard electric drill and drill bit set

•Crimping tool (if using solderless crimp connectors)

•12-volt test light or digital multimeter

•Wire brush or scraper (to remove paint for a good ground connection to vehicle)

•Soldering iron and rosin core solder (if you're going to solder your connections)

Amplifier Installation Kit:

You will need an amplifier installation kit to install your amp properly because it contains all the wire and connectors that you will need to hook up your new amp right the first time. If you want to purchase these items separately you will need the following:

•20-25 feet of 8 gauge wire

•50 amp fuse or circuit breaker (to be hooked up at the battery)

•20 feet of 18 gauge wire for the remote turn-on/ power antenna lead

•RCA cable (for signal input from radio)

–20 feet for trunk installation

–12 feet for under-seat installation

•Two 8 gauge ring terminals (one for the battery connection and the other for the ground connection at the amp). You may need two additional ring terminals if you are using a circuit breaker at the battery.

•Two 8 gauge barrel connectors (you may need these depending on what type of fuse holder you have)

•Two 8 gauge spade terminals (to hook up power at the amp)

•Eight 12 gauge spade terminals for subwoofers or 16-18 gauge spade terminals for other speaker connections to amp

•One 18 gauge spade terminal for remote turn-on/ power antenna lead

Professional Tip

Bigger is better

Stereo installation dealers sell extra thick power and speaker wires to ensure best sound. Look for 8 gauge power wire, especially if you have several amplifiers.
