Read this entire guide fully before attempting your installation.

WARNING: BE AWARE! Use of this amplifier at extreme high volumes for extended periods of time may cause hearing loss and or hearing damage. During periods of prolonged high volume levels it is recommended that you use ear safety devices.

Playing Cadence amplifiers at high volume levels while driving will impair your ability to hear necessary traffic sounds. While driving always keep your sound volume at reasonable levels. We at Cadence want you listening for many years to come.

When installing the amplifier, secure it tightly. An unmounted amplifier in your car can cause serious injury to passengers and damage to your vehicle if it is set in motion by an abrupt driving maneuver or short stop.

INSTALLATION

BATTERY VOLTAGE:

Cadence Momentum CSA amplifiers are rated and regulated to 14.4 volts and below.

Maximum input voltage is 16 volts while the minimum voltage is 12 volts.

*** DO NOT EXCEED 16 INPUT VOLTAGE. ***

PROTECTION CIRCUITRY:

Cadence amplifiers incorporate many outstanding protection circuits to help protect the amplifier from being damaged during operating conditions.

Thermal Protection: When the amplifier reaches an unsafe operating temperature of 80 degrees Celsius the amplifier will turn off. Once the amplifier cools down, simply reset the amplifier by its Remote connection, (turn the amplifier off and then on again once you have given the amplifier a chance to cool down) and the amp will once again begin to play.

If you live in a hot climate we suggest installing additional cooling fans in your trunk to exhaust the hot air which can build up in the trunk this will help keep the ambient temperature in the trunk as low as possible so that your amps work flawlessly and without any musical interruption.

Clipping or total shutdown may also be a result of a bad ground connection or loose ground. If you find that your speakers and speaker wires are not shorted, please check your ground connection.

Input Overload Protection: This circuit will either shutdown the amplifier completely or make the amplifier spurt on and off indicating that it is in a diagnostic condition. Turn the system off and reduce the gain on the amplifier or volume from your head unit, this should result in a corrected condition.

DC Offset Protection: Should any DC voltage try to enter the amplifier via the speaker terminals it will cause the amplifier to shut down and not operate until this condition is remedied. This circuit will also protect damaging high DC voltages from reaching your speakers should your amplifier ever malfunction.

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 amplifier. Cadence amplifiers operate on 12-volt negative ground systems only.

It is recommend that you layout your sound system design on paper first. This will help you during the installation so that you will have a wiring flow chart and not miss-wire any of your components.

Mount the amplifier in the trunk or hatch area of your vehicle. Never install an amplifier in the engine compartment or on the fire wall. Please be sure to leave breathing room around the amplifier heat sink so that it can dissipate the heat it produces efficiently.

The amplifier can be installed either horizontally or vertically.

When mounting the amplifier on the trunk floor, 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.

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 amplifier 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.

POWER/GROUND WIRING:

The Momentum CSA series amplifiers are supplied with built-in fuses, never replace the fuse that the amp came with, with one of a larger value.

We suggest you construct a Red wiring harness with 2 additional fuses. One fuse should be located near the car battery. This fuse near the battery offers protection against damage from short circuits to the car chassis between the battery and the amplifier. A second fuse closer to the amplifier offers additional safety to the amplifier itself. This fused red power wire should be attached to the amplifier power terminal marked +12V .

FEATURES

The wire harness should be made of red primary cable of at least 8 gauge for the

CSA1000.2 and at least 4 gauge for all other larger models. The harness should terminate in a large ring terminal for connection directly to the positive terminal of the car battery. Use a spade plug to attach the wire, which connects to the amplifier location marked + 12V.

A second black color wire of equal gauge should be used as a ground connection to a welded chassis member. When connecting the ground wire make sure that there is no paint or other insulator blocking a good ground connection. When installing multiple amplifiers, mount them in close proximity so that they can all share the same ground point. Attach the black ground wire to the amplifier screw terminal marked Ground .

We recommend that you use the Cadence AMPKIT4 or AMPKIT8 amplifier installation kits, which contains all the cabling and accessories necessary for a good, reliable installation.

Over the years we have received amplifiers back to our service department with melted power/ground terminals. The cause of this is a bad ground connection. When there is a lack of good ground, heat builds up at the weakest point which happens to be the contact screw of the amplifier terminal. Over time the heat generated will begin to melt the terminal. It is a good practice to feel the power and ground wires with your hands, near their amplifier connection after having played the amp for a while. If the wires feel hot to the touch you probably have a bad or loose connection. If you are sure of your connections and the wires still feel hot to the touch, you should upgrade the gauge of wire to next heaviest gauge (see wiring diagram, page 5).

SETTING THE CONTROLS:

AUDIO PREAMP INPUT

The Momentum CSA series amplifiers feature RCA pre amp inputs. Run RCA cables from your sound source to the inputs of the amplifier. 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 amplifier.

BUILT IN LOW PASS ELECTRONIC FILTER

All Momentum CSA series amplifiers feature 12dB per octave fully adjustable low-pass and high pass electronic filters.

For Low Pass sub woofer systems, set the FILTER switch to LOW PASS. Now the knob marked LPF or LOW PASS will control the low pass frequencies anywhere from 50Hz to

500Hz depending on the model. A frequent error made is setting the low pass frequency too low, especially when using a vented sub woofer enclosures. We recommend that for most installations you do not set the frequency knob lower than 80 to 100Hz (the

12 o’clock position).

When using the amplifiers for component speakers or co-axials, you will want to set the

FILTER switch to HIGH PASS. The HPF control knob adjusts the high pass frequencies between 120Hz and 3KHz. Do not attach tweeters directly to the amplifier, (even in the high pass mode) without a passive crossover to protect them.

SUBSONIC FILTERING

For sub woofer installations with passive LP crossover, you can set the amplifier’s

FILTER switch to HIGH PASS while setting the SUB SONIC 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.

GAIN (INPUT LEVEL CONTROL)

To adjust the GAIN turn the control using a small flat head screwdriver fully counter clock wise to the minimum position. Do not apply any pressure while turning as this might break the control unit. Adjust your radio volume level to maximum volume. Now turn the level control on the amplifier clockwise towards the Maximum marking until audible distortion occurs. When you begin to hear any distortion in the sound, back down one notch and your amp is set. It is helpful to have a second person to help you set the gain.

When setting up a multi-amp system, set each amplifier’s gain separately. Start off with the bass amplifier, then adjust the highs amplifier’s level control to match.

Once you are satisfied with the level control settings, use any equalizer controls to adjust the system tonal level for personal preference. Keep in mind that after equalizing, you may have to go back and reset the amplifiers level controls.

* The level control of any car amplifier should not be mistaken for a volume control. It is a sophisticated device designed to match the output level of your source unit to the input level of the amplifier. Do not adjust the amplifier gain to maximum unless your input level requires it. 4

If your head unit has 2 pairs of RCA output jacks, input Front Left and Front Right in to Channels 1 and 2. Then attach radio output Rear Left and Rear Right to Channels 3 and 4. Should your head unit have an additional subwoofer RCA output, that typically needs to be attached to a separate subwoofer amplifier.

When configuring a 4 channel amplifier to a 3 channel system, you can use an RCA Y adaptor to send the subwoofer preamp signal to channels

3 and 4 and bridge those channels to the subwoofer. Use Y adaptors to mix channels 1 and 3 and input them into RCA Channel 1, then mix channels 2 and 4 and input them into RCA channel 2. The result will be preserved Left and Right balance with constant subwoofer output.
