Introduction Thank you for purchasing this Rockville dB Series amplifier. Over the years, the technology used to create audio amplifiers has grown by leaps and bounds. Our competition is satisfied with just continuing to build the same units year after year without thought for improvement, but not Rockville. We consider it our mission to use our expertise in developing the latest technologies and to bring you the absolute best sounding amplifiers on the market and of course at a reasonable price.
Features Bass Equalization Circuitry A narrow “Q” peaking equalization circuit is included in the amplifiers. The equalization system is preset at 45Hz. The equalizer control allows you to add up to 12dB of bass boost. Utilize the bass equalizer to tailor your bass response to your systems needs. Make sure your speakers can handle the extra power output! It would be foolish to add 12dB of gain to low excursion 8˝ and 10˝ Sub woofers or mid ranges and tweeters. It’s a sure way to blow your speakers.
Features 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. You must reset amplifier by turning it OFF and then ON again after correcting a diagnostic condition (turn your radio off and then on again).
Installation Installation Basics Before you begin your installation, disconnect the NEGATIVE(-) terminal from your car’s battery. This safety precaution will avoid possible short circuits while wiring your amplifier. Rockville amplifiers operate on 12-volt negative ground systems only. It is recommended 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.
Wiring 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 the amplifier on with your car’s ignition.
Settings Adjusting The System Once the system is operational, the first thing to do, is set all crossover points to approximate settings. In the case of the basic sub woofer system Low Pass filter crossover at 100Hz or so. Set the bass equalizer controls to 0 dB. Now you should set the amplifiers Input Sensitivity adjustment. The knob accessible on the side of the amplifier marked LEVEL or INPUT LEVEL adjusts the input sensitivity.
100Hz (the 12 o’clock position). When using the amplifiers for component speakers or coaxial, you will want to set the CROSSOVER MODE switch to HIGH PASS. The HPF control knob adjusts the high pass frequencies between 60Hz and 1.2KHz. Do not attach tweeters directly to the amplifier even in the high pass mode without a secondary passive crossover to protect them. Audio Preamp Input The dB Series amplifiers feature RCA pre amp inputs. Run RCA cables from your sound source to the inputs of the amplifier.
5 Channel Amp Configurations 5 Channel Amp with 2 Channel Input If your head unit has one single pair of RCA outputs, input them in to the amplifiers Channel 1 and 2 input jacks and set the Input Mode Switch to 2Ch. The amplifiers preamp circuitry will automatically mix all the channels and output will occur on all 5 channels. There will be Left and Right balance with constant subwoofer but no Front to Rear Fader Control.
5 Channel Amp with 4 Channel Input If your head unit has two pairs of RCA outputs, input Front Left and Front Right in to amplifier channels 1 and 2 input jacks. Rear Left and Rear Right in to amplifiers channels 3 and 4 input jacks. Set the Input Mode Switch to 4Ch. The amplifiers preamp circuitry will automatically mix all the channels and output will occur on all 5 channels. There will be Left and Right balance and Front to Rear fader with constant subwoofer.
5 Channel Amp with 5 Channel Input If your head unit has three pairs of RCA outputs, input Front Left and Front Right in to amplifier channels 1 and 2 input jacks. Rear Left and Rear Right in to amplifiers channels 3 and 4 input jacks. Subwoofer output in to channel 5. If your head unit has only a single subwoofer output, use a Y adaptor to feed both channel 5 inputs. Set the Input Mode Switch to 5Ch.
5 Channel Amp Speaker Wiring Minimum impedance for channels 1 through 4 is 2 ohm stereo. Channel 5 minimum impedance is 2 ohm mono capable.
4 Channel Amp Configurations 4 Channel Amp with 2 Channel Input If your head unit has one single pair of RCA outputs, input them in to the amplifiers channel 1 and 2 input jacks. The amplifiers preamp circuitry will automatically mix all the channels and output will occur on all 4 channels. There will be Left and Right balance but no Front to Rear Fader control.
4 Channel Amp with 4 Channel Input If your head unit has two pairs of RCA outputs, input Front Left and Front Right in to amplifier channels 1 and 2 input jacks. Rear Left and Rear Right in to amplifiers channels 3 and 4 input jacks. The amplifiers preamp circuitry will automatically mix all the channels and output will occur on all 4 channels. There will be Left and Right balance and Front to Rear fader.
4 Channel Amp Speaker Wiring Install any combination of speakers independently on all 4 channels being careful not to load any single channel below 2 ohm stereo. For typical 6˝ x 9˝ or 6.5˝ or component speaker installs, set the Crossover Mode Switches to Full Range.
4 Channel Amp in 3 Channel Mode Channels 1 and 2 should be wired to speakers no lower than 2 ohm loads per channel in stereo. Channel 3 and 4 should be bridged as per the diagram wiring the woofer to channel 3’s positive (+) terminal and channel 4’s negative ( – ) terminal. Set the crossover mode switch of channels 1 and 2 to either Full Range or High Pass, while channels 3 and 4 should be set to Low Pass.
4 Channel Amp Bridged to 2 Channels When bridging the four channel amplifier, make sure that your final woofer impedance on each bridged channel is no lower than 4 ohms. Set the Channel 1 and 2 Crossover Mode Switch to LPF; set the Channel 1&2 and Channel 3&4 Crossover Mode Switches to LPF. Begin by setting the crossover frequency controls to 100Hz and tuning from there.

2 Channel Amp Configurations 2 Channel Amp Input Connect your head unit’s RCA outputs to the amplifiers Left and Right RCA input jacks. The dB25 2 channel amplifier features RCA pre-amp line outputs for feeding of a full-range signal to a secondary full-range amplifier in a multi-amp system.
2 Channel Amp Speaker Wiring Install any two or four speakers being careful not to load either channel below 2 ohm stereo. For typical 6˝ x 9˝ or 6.5˝ speaker installs, set the Crossover Mode Switch to Full Range. If you are using a system with a sub we recommend setting the crossover switch to high pass.
2 Channel Amp Subwoofer Wiring Install any subwoofer being careful not to load the amp below 4 ohm mono. Set the Crossover Mode Switch to Low.
Class D Monoblock 2 Ohm Amp Configurations Class D Monoblock Amp Input Connect your head unit’s RCA outputs to the amplifiers Left and Right RCA input jacks. All dB series monoblock amplifiers feature RCA pre-amp line outputs for feeding of a full-range signal to a secondary full-range amplifier in a multi-amp system.
The dB16, dB15, dB14, dB13, and dB12 are all 2 ohm stable monoblock amplifiers. No matter how many woofers you choose to wire up to these models, the final impedance should not fall below 2 ohm. Please see page 30 and 31 for various speaker impedance configurations. The dual positive and negative terminals are connected in parallel inside the amplifier. Connecting two speakers, each to one set of positive and negative terminals, will result in a parallel speaker connection.
Twin Amp Bridging The dB14, dB15, and dB16 can be bridged together for double the power output into a single 4-ohm load. Remember, when bridging amplifers you must bridge them to a 4 ohm load. Input the head unit signal into the MASTER amplifer and set the Bridged Mode switch to Output Master. Use a MONO RCA to RCA cable to send the fully processed signal from the MASTER amplifier to the secondary SLAVE amplifier and set the Bridged Mode switch to Input Slave.
