Replacing the antique Becker with a new CD deck
When you replace the Becker Grand Prix tape/radio with any aftermarket CD head unit there are some things to consider. Yes, you can use the existing power, ground, and speaker wires but since all aftermarket head units come with electronic fader built-in, you want to access the speaker wires before they reach the dirt-collecting rotary fader in your console. All aftermarket units have four ohm (impedance) speaker outputs, and the aweful o.e. paper-faced ones are 2.1 ohms or something just as low. You will want to replace the original speakers with aftermarket coaxial ones the same size (4"front, 5.25"rear). To wire a ten disk changer, mount the changer in the trunk and run the shielded cable through the rubber-plugged pass through behind the back of the rear seat. Un-snap the plastic threshold cover off and carefully lay the wire down the side of the car and up, behind the back of the cosole to the head unit. Head unit power is a big jump from the days of the Becker unit, but it cannot compare to the clarity provided by a four channel amplifier. Remember that when you are talking about watts per channel you are not talking about how loud...that's the volume control. Wattage means clear! P.
