REMOTE TURN ON CONNECTION:

The remote turn on connection is located on the barrier strip next to the power and ground connections. This connection is responsible for turning the amplier on and off with

the rest of the system. A smaller gauge wire can be used to make this connection to your radio’s power antenna lead. Should your system not have any turn on leads, you can

wire the remote terminal to an accessory lead, which turns on, with your cars ignition.

INSTALLATION BASICS:

Before you begin with your installation, disconnect the NEGATIVE (-) terminal from your car’s battery. This safety precaution will avoid possible short circuits while wiring your

amplier. Cadence ampliers operate on 12-volt negative ground systems only.

It is recommend that you layout your sound system design on paper rst. This will help you during the installation so that you will have a wiring ow chart and not miss-wire any

of your components.

Mount the amplier in the trunk or hatch area of your vehicle. Never install an amplier in the engine compartment or on the re wall. Please be sure to leave breathing room

around the amplier heat sink so that it can dissipate the heat it produces efciently. When mounting the amplier on the trunk oor, be sure to watch for your gas tank, gas

lines and electrical lines. Do not drill or mount any screws where they might penetrate the gas tank of your car.

SETTING THE CONTROLS:

AUDIO PREAMP INPUT

The QRS Series ampliers feature RCA pre amp inputs. Run RCA cables from your sound source to the inputs of the amplier. We suggest the use of high quality shielded

RCA patch cords to help reduce and eliminate unwanted electrical noise to your system. Be sure to run the RCA cables on the opposite side of the vehicle that you used to

carry the power and ground leads of the amplier.

SUBSONIC FILTERING

For sub woofer installations with a passive LP crossover using models Q5000, Q4000, Q3000, and Q2000, you can set the amplier’s CROSSOVER MODE selector to HIGH

PASS while setting the FREQUENCY KNOB to 30Hz, this will act as SUBSONIC FILTER for all signals below 30Hz. This is especially useful for vented enclosures where the

port tuning frequency falls below the sub woofer tuning frequency to protect against sub woofer unloading. Models Q6000m, Q7000m, Q8000m, and Q9000m come with a

built in subsonic lter that ranges from 10Hz to 50Hz.
