How to fix engine noise (static type) in my Rockville Subwoofer?
Poor quality RCA cables are often the cause, as they can pick up radiated noise. Use high-quality cables and route them away from power cables.
What causes engine noise (alternator whine) in my Rockville RW8CA and how to fix it?
Verify that the RCA grounds are not shorted to the vehicle's chassis. Also, ensure that the head unit is properly grounded.
What to do if there is no output from my Rockville RW8CA?
Verify that all fuses are working correctly and that the unit is properly grounded. Check that the Remote Input (Turn-On) has at least 5VDC. Ensure the RCA audio cables are correctly plugged into the inputs and inspect all speaker wiring.
What to do if my Rockville RW8CA amplifier will not power up?
First, ensure you have a solid ground connection. Then, verify the Remote Input (Turn-On) receives at least 5VDC and that the (+) terminal has battery power, with a minimum of 12V. Inspect all fuses, replacing them if necessary. Finally, check if the Protection LED is on; if so, briefly turn off the amplifier and then turn it back on.
Why is my Rockville RW8CA distorted and the amplifier getting very hot?
Ensure the Input Level Control matches the head unit's signal level, keeping it as low as possible. Verify all crossover frequencies are correctly set and check for short circuits in the speaker leads. Confirm the speaker impedance matches the amp model's requirements and that there's sufficient air circulation around the amp. Adding an external cooling fan may be necessary in some cases.
What to do if the Protection LED comes on when my Rockville Subwoofer amplifier is powered up?
Check the speaker leads for short circuits. Reduce the head unit's volume to prevent overdriving. Disconnect the speaker leads temporarily and then reset the amplifier. If the Protection LED remains illuminated, the amplifier may be faulty and require servicing.
Why is there a high hiss in the sound from my Rockville RW8CA, and how can I eliminate it?
Disconnect all RCA inputs from the subwoofer's control panel. If the hiss disappears, plug in the component driving the amplifier and unplug its inputs. Repeat until you find the faulty component. Set the amplifier's input level control as low as possible for the best signal-to-noise ratio. Maximize the head unit's volume (without distortion) and minimize the amp input level.
Why is there a squealing noise present in my Rockville Subwoofer?
Check the RCA interconnects for improper grounding.
Why is the output low on my Rockville RW8CA Subwoofer, and how can I increase it?
Try resetting the Level Control. Also, check the Crossover Control settings.
