Audio System AD 3000 Car Audio Power Amplifier
400,00 €
Audio System AD 3000 is a car audio power amplifier designed for the low-frequency section of an in-car sound system. It delivers up to 3000 W RMS at 1 ohm, 14.4 V and less than 1% THD. Adjustable low-pass and subsonic filters allow the operating range to be matched to the system. The included bass level controller makes everyday level adjustments more convenient.
Audio System AD 3000 is a car audio power amplifier designed for an in-car sound system. It delivers 1200 W RMS into a 4-ohm load. Output rises to 1850 W at 2 ohms and 3000 W RMS at 1 ohm. All ratings apply at 14.4 V with less than 1% THD.
What This Amplifier Is Designed For
This model is intended for the low-frequency section of a car audio system. Its 10-180 Hz frequency range does not cover the entire audible spectrum, so it should not be selected as the main full-range amplifier.
Match the amplifier and subwoofer according to the final impedance of the speaker or combined speaker system. The nominal load is determined by the speaker voice coils and how they are wired. The amplifier’s stated output increases as impedance decreases. This must be taken into account when choosing the vehicle’s power supply system.
Matching the Input Signal
Input sensitivity is adjustable from 0.2 to 5 V. This range allows the amplifier to be matched to the output signal level of the audio source. The sensitivity control is not intended to serve as an everyday volume control.
Begin with a lower gain setting and increase it gradually. Stop if clearly audible distortion appears. Careful adjustment helps avoid unnecessary noise and input overload.
Filter and Bass Adjustment
The low-pass filter cutoff frequency can be set from 40 to 180 Hz. Choose an initial setting that complements the operating range of the vehicle’s other speakers. The aim is a smooth transition without a pronounced overlap or gap between frequency ranges.
The subsonic filter is adjustable from 10 to 50 Hz. It restricts the signal below the selected threshold. Start with a low setting and raise it only when required by the subwoofer being used.
The bass boost frequency can be selected within the 30-80 Hz range, while its level is adjustable from 0 to 12 dB. Begin at 0 dB and first set the input sensitivity and filters correctly. Increase the additional boost sparingly to avoid distortion.
A signal-to-noise ratio above 90 dB helps keep background noise low. The final result also depends on setting the input sensitivity correctly.
Installation Location
The enclosure measures 64 × 5.6 × 23.2 cm and weighs 8.26 kg. The chosen installation location therefore needs a solid base and secure mounting. Allow additional space for wiring and air circulation.
The thermal protection threshold is 80°. Do not cover the enclosure or install it where air cannot circulate freely.
Included Equipment
A bass level controller is included. It allows the low-frequency level to be adjusted without changing the main filter settings. Plan a convenient mounting position for the controller before installation.

FAQ
Is this amplifier designed for the full audio frequency range?
No. The specified 10-180 Hz frequency range and adjustable filters make this model suitable for the low-frequency section of the system.
How should I choose the correct load?
Use the final nominal impedance of the connected speakers as your guide. The way the voice coils or multiple speakers are wired can change this value.
How should I set the input sensitivity?
Start with a lower gain setting, then increase it gradually. Use the audio source at a normal listening level during adjustment and listen for distortion.
In what order should the filters be adjusted?
First, match the cutoff frequency to the other speakers. Next, set the subsonic filter, and adjust the bass boost only after those settings have been established.
What should I consider when choosing an installation location?
Choose a solid mounting surface and leave enough room for air circulation and wiring. The enclosure must not be covered or pressed against other surfaces.
