Page 2: Important Safety Instructions
We have spared no expense in designing these amplifiers, creating the most rugged, reliable, powerful and best performing amplifiers. In fact we are so sure of the quality we backup every dB Series amplifier with one year warranty which exemplifies our commitment to the end user. (See enclosed warranty card for details.) -
Page 3: 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. - Page 4 As connections can work loose due to vehicle vibrations we recommend periodically tightening all power and ground connections. The majority of the dB Series amplifers are supplied with built-in fuses. Never replace the built in or supplied external fuse with one of a larger value.

Page 6: Adjusting The System
Audio Preamp Input The dB Series amplifiers feature RCA pre amp inputs. Run RCA cables from your sound source to the amplifier inputs. We suggest you use high quality, shielded RCA patch cords to help reduce and eliminate unwanted electrical noise to your system. Use good quality RCA interconnect cables. Cheaper cables usually have poor shielding that can cause interference pickup. - Page 7 Here is a simple formula to help you figure out the proper Subsonic HPF setting for your particular ported enclosure. Keep in mind that one octave up is double the frequency and one octave down is half the frequency: 1. Divide the tuning frequency of your port by two. This is one octave lower than your tuning frequency. 2.
- Page 8 Class D Monoblock 2 Ohm Amp Configurations Class D Monoblock Amp Input All dB series monoblock amplifiers feature RCA pre-amp line outputs for feeding of a full-range signal to a Connect your head unit’s RCA outputs to the amplifiers Left and Right RCA input jacks.
- Page 9 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.
- Page 10 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.

Page 12: Important Note
Twin Amp Bridging IMPORTANT NOTE: SUBWOOFER MINIMUM CONNECT THE TWO SPEAKER NEGATIVES TOGETHER WITH IMPEDANCE 4 OHMS A # 12 WIRE STRAP. IF THIS STRAP IS NOT INSTALLED, THE AMPLIFIERS COULD BE DAMAGED! - Page 14 Power And Protection Circuitry dB Series amplifiers feature our unique IC controlled protection circuitry. This sophisticated circuit constantly monitors the heat sink internal temperature and various voltages, adjusting the amp automatically and protecting it from dangerous conditions. The 2 LED’s located on the side of the amplifier provide indication of the amplifier status, the Power LED will light when the amplifier is receiving proper power, ground and remote voltages and the IC monitoring sequence indicates the amp is functional.

Page 15: Battery Voltage
Battery Voltage Rockville dB Series amplifiers are rated and regulated to 13.8 volts and below. Increasing voltage to 14.4 volts will increase the power output of the amplifier in the same proportion. Maximum input voltage is 14.4 volts while the minimum voltage is 12 volts. -

- Page 20 Woofer Wiring Guide Please note that the minimum impedance load for single dB Series Amplifiers is 2 ohm stereo and 4 ohm mono bridged. Lower impedance loads will cause overheating and may damage the amplifiers. Do not mix different impedance speakers in series and/or parallel combinations, as unequal power sharing and acoustic outputs will result.
