3.Select a speaker position using the test PSB, then move the PSB to the same module location on the opposite side of the speaker section of the display.

•The PSB lights up as soon as you plug it in, showing both left and right speaker positions are selected.

4.Attach the test PSB to a second speaker in a group, press the PSB and hold the button for at least one second.

•If the speaker limit setting on the 980 is set to 1, the PSB will not come on.

•If the speaker limit is 2 or higher, the PSB will come on in both the first and second speaker position (factory default is 2, with 980 limit switches all in the OFF position). The 902/903 displays the two speaker positions alternately in the speaker’s PG window.

DISPLAY COMPONENT HOOKUP

It is now time to begin installing the car audio head units, EQs, amplifiers and speakers. If you’ve followed the instructions so far, you will have a working system in short order. This section assumes that the compo- nents have been mounted onto removable panels or onto the front portion of your fixture. You will obviously need to connect the wires from the components to the switching system and DC distribution system, so you may wish to map out a plan for that process that allows easy access to the modules from the front or the rear of your display.

Usually, it works out best to mount the components to be located at the bottom of your display first, and work toward the top of the display so you can avoid masses of hookup wire hanging down from above. Take your time mounting the components and be sure to save their boxes and accessories, so that you can offer your customer a new or almost new unit when you later take the component out of the display.

1. Install the First Products

Install one product in each of several groups in order to get a simple system running. For example, install a head unit, a processor (if any), a two-channel amp, and a pair of front speakers (see Appendix B for detailed hookup drawings). Leave your power supply ON and your battery, if any, connected, but be careful using metal tools.

A.Connect a head unit’s high/low-level audio outputs and DC power inputs to a product position on the 910 Module.

•Connect the low-level output to the red (R) and white (L) female RCA jacks using short, high quality patch cables.

•Connect the unit’s front and rear high-level (speaker) outputs to the two terminal blocks next to the “Power” terminal block. Observe the polarity

legend printed on the circuit board under the

terminal plugs.

• Connect the two-pin plug of the PSB’s cable, if
PSBs are used, to the small 2 pin headers on the
910 circuit board at the corresponding product
position. Press the PSB into the 3⁄4” hole you	PSB
drilled earlier in the mounting panel or display
fixture. Plug the connector into the PSB with the
cable exiting on top as shown.
