BEFORE YOU BEGIN THE INSTALLATION

Before you install your amplifier, read all the instructions in this owner’s manual. You should be able to answer all of these ques- tions about your vehicle’s electrical and auto sound systems.

Does my vehicle have an auto sound system, such as a car stereo or CD player, already installed? (You must have an existing auto sound system to use this amplifier.)

How do I connect a wire to the fuse box?

Which of the auto sound system’s wires is the power wire?

Which of the auto sound system’s termi- nals are low-level outputs and which are high-level (speaker) outputs?

Also, be aware that installation in your vehi- cle might require cutting or modifying your vehicle.

Choosing a Mounting Location

A good location for mounting the amplifier is in your vehicle’s trunk. Wherever you decide to mount it, choose a mounting location that:

Does not interfere with the vehicle’s operation

Lets you drill mounting holes without damaging other vehicle components

Allows enough space around the cooling fins for proper airflow and cooling

Lets you easily see the amplifier’s POWER and PROTECTION indicators
