and thank you for choosing this RODEK car audio active subwoofer RN110A. To maximize the performance of your complete car audio system, it is recommended that you acquaint yourself thoroughly with the capabilities and features of this product. Therefore read this manual carefully, before attempting the installation of the RODEK RN110A and retain the manual and your purchasing/installation receipts for future reference.

Before you attempt the installation of your RODEK active subwoofer, it is recommended to map out the complete audio system and the respective wiring required. Please note that - because of possible interference problems with the existing car electrics and electronics - especially the routing of the signal cables and the chassis ground connection will have a profound impact on the performance of the overall system. Secondly, the correct mounting location needs your attention too (proper cooling of the amp module!). Use only quality installation material and if you have only little or no experience with complex car audio installations, we strongly recommend you to consult your nearest authorized RODEK dealer/installer.

3. MOUNTING

The mounting location for your active subwoofer should be carefully selected, preferably in the trunk compartment of your car! In the interest of passive driver and passenger safety, the RN110A should be securely mounted, and precautions must be taken to allow sufficient cooling. The amp module can get quite hot during operation. Note that the crossover controls must remain accessible after installation is completed.

4. ELECTRICAL WIRING

IMPORTANT! Disconnect the positive power terminal ("+12V") or remove the main fuse near the car battery before you start any wiring work!

The power supply of the car audio system must be disconnected until the entire wiring installation is completed.

Use rubber grommets when running cables through any metal or sharp plastic panels, to prevent accidental shorting or shearing. Make sure the cables do not interfere with normal operation of the vehicle. Especially the music signal cables (RCA interconnects) should be kept far away from any potential sources of electrical interference i.e. electronic vehicle management systems (engine computers, relays etc.) fuel pumps, wiring harnesses etc.

4.1 CONNECTION OF POWER CABLES

Run the positive power cable ("+12 V") directly from the positive terminal of the car battery to the amp-module. Make sure the power cable makes good contact to the battery; i.e. use an appropriate battery clamp that accepts big gauge power cables! For protection of your car audio system and your entire car against electrical fire hazards from a shortcircuit of the main power cable with chassis ground, you must insert a main fuse (holder) within the first 30cm of the battery. The fuse type/value should be matching the limitations of your main power cable and the requirements of your car audio system. For example 60 A fuse when using the 20 mm² power cable. Now you route the ground cable to the amp-module. It is best to keep the ground cable ("-12V") as short as possible, i.e. to find a chassis contact very close to the amplifier. The ground power cable must have the same cross-section as the positive power cable. It is recommended to use a corrosion-resistant gold-plated power ring or a massive ground clamp between the ground cable and the chassis ground point.

Keep in mind that audible interferences and problems originating in the power supply of the amplifier are mostly based on a bad ground contact.

4.2 RCA INTERCONNECTS / REMOTE LEAD

Carefully run the RCA audio signal interconnect(s) and the remote switching cable from the head-unit to the amplifier. The audio signal cables should be routed completely separate from the power cables. Use only double or triple shielded quality cables!

Connect the remote wire lead to the remote output of the headunit and to the remote input terminal of the amplifier. Finally connect the RCA interconnect cable(s) to the respective outputs on the head-unit and the RCA inputs of the amp-module.

4.3 HIGH LEVEL INPUT

If your headunit does not have RCA outputs, you can use the "HIGH LEVEL INPUT".

To use this, connect the "HIGH LEVEL INPUT" to the loudspeaker outputs of your headunit or parallel to the rear speakers in your car.

If your headunit does not support a remote output, you can use the automatic turn on/off function. This function is controlled by the audio signal itself. Therefore please set the "SWITCH" to "ON".

5. CROSSOVER SETTINGS

5.1 ADJUSTMENT OF LOWPASS FILTER

To drive the active subwoofer system, the integrated electronic crossover always operates in lowpass mode. The RN110A features a variable lowpass filter from 80Hz to 200Hz.

You can set an appropriate lowpass crossover frequency.

For this purpose, open the input gain control – the knob should point to "noon" – so you can hear the subwoofer playing. Ideally, the low-pass cut-off frequency should be set between 80 to 200 Hz – and this setting has to be entirely determined by ear. Try to find lowpass crossover frequency setting that gives you a "full-bodied" bass reproduction with enough impact in the upper bass range.

Note: If the lowpass crossover frequency is set too low, the sound will have a tendency to sound extremely soft and lowend heavy!

5.2 ADJUSTMENT OF INPUT SENSITIVITY

To reach a maximum noise-free dynamic headroom from each individual head unit/active subwoofer combination, it is important to set the respective input gain controls correctly. The input level settings determine the actual signal-to-noise ratio, and they are also responsible for obtaining the maximum distortion-free SPL (sound pressure level) from your specific setup.

Turn-on your head-unit and set the volume control to approximately 3/4 of full volume, while playing a dynamic track from a CD. Slowly increase the GAIN adjustment control of the input of the RN110A.

Turn up the GAIN control knob until you can just about hear distorted bass sounds.

5.3 ADJUSTMENT OF PHASE SWITCH

The phase function of your RODEK RN110A can be set with the corresponding knob. The phase-shift control enables you to match the acoustical phase relations of subwoofer and the speaker system playing in the front doors, either a component or a coaxial system.

The target is that both speaker systems, normally separated by aprox. 3m of distance are playing acoustically "in-phase" at the driver's seat location. A good match of the acoustical phase between subwoofer and the system in the front doors will give you the impression of bass sounds coming from a place in front of you.

The second advantage is, that the upper bass region - i.e. where the sound waves radiated by the subwoofer and the kickbass or front door mounted component system is crossing over – will sound considerably more precise and tight. This phase adjustment

can only be determined by ear, there is no rule of thumb to find a good match, and you will definitely need somebody to help you. To judge the effect of the phase-shift adjustment, you must sit in the driver's seat, and somebody must adjust the phase shift control until the sound reproduction in the bass region is best.

5.4 BASS BOOST CONTROL

With the BASS BOOST control potentiometer you can add more output in the 60Hz region. Please note, that this is a matter of taste. If you are not sure, leave this potentiometer fully closed, i.e. rotated counter-clockwise.
