Frequently Asked Questions about Box Audi ARC8 A4 B9

What power does the ARC Audio ARC8 Subwoofer provide in the Audi A4 B9?

The ARC Audio ARC8 Subwoofer for the Audi A4 B9 offers a recommended power of 150 to 250 Watts RMS. The subwoofer is available in two versions - 2 Ohm and 4 Ohm, allowing for flexible installation options and customization based on individual requirements. The maximum load capacity of the ARC8 is 300 Watts. This means it is also suitable for intense applications and music genres that require powerful bass. With a sound pressure level of 85 dB/1W/1m, it ensures clear and strong sound, enhancing your audio experience in your Audi A4 B9.

How big is the ARC Audio ARC8 Subwoofer and does it fit perfectly in the Audi A4 B9?

The ARC Audio ARC8 Subwoofer has a size of 8 inches, which is 20 cm. Its dimensions are 400 x 245 x 184 mm, plus a 30 mm spacer. The subwoofer is specifically designed for the spare wheel well of the Audi A4 B9 Avant, which has a volume of 13 liters, to optimally utilize the downfire technology. The compact design allows for seamless integration without losing space in the trunk. The construction from 12 mm thick multiplex with a black felt covering also provides a robust and appealing aesthetic inside the vehicle.

What are the technical parameters of the ARC Audio ARC8 that define its performance?

The ARC Audio ARC8 Subwoofer is equipped with a range of technical parameters that determine its performance. The resonance frequency (Fs) is 24.7 Hz, allowing for deep bass. The replacement mechanical efficiency (Qes) of 0.367 and the mechanical quality factor (Qms) of 3.572 contribute to an overall quality factor (Qts) of 0.332, promoting precise bass reproduction. The VAS value is 43.9 L, and the linear excursion (Xmax) is +/-15 mm. These parameters ensure that the subwoofer produces deep and clear bass, making your music intense and vibrant.

How does the downfire principle of the ARC Audio ARC8 work in the Audi A4 B9?

The downfire principle of the ARC Audio ARC8 Subwoofer in the Audi A4 B9 optimally utilizes the spare wheel well to deliver rich and full bass. In this design, the subwoofer is mounted to radiate bass downward, which is enhanced by the 13-liter space of the well. This placement produces deeper frequencies, as the floor serves as an additional reflection surface. The advantage of this technique is a uniform bass reproduction in the vehicle that requires no additional adjustments or box rebuilds, representing a simple and effective bass optimization.

What Ohm versions are available for the ARC Audio ARC8 and what advantages do they offer?

The ARC Audio ARC8 Subwoofer is available in two Ohm versions: 2 Ohm (D2) and 4 Ohm (D4). These variants allow for versatile integration into existing sound systems. The 2-Ohm version is suitable for powerful amplifiers and offers higher output power, delivering intensely irresistible bass. The 4-Ohm version also provides flexible connection options, ideal for systems that require less power or where power consumption is a critical factor. Both versions are equipped with 2x2 connection cables that extend from the enclosure to ensure easy installation and retrofitting.

What tips are there for installing the ARC Audio ARC8 in the Audi A4 B9?

When installing the ARC Audio ARC8 Subwoofer in the Audi A4 B9, it is important to consider the dimensions of 400 x 245 x 184 mm and the additional 30 mm spacer. For optimal performance, the subwoofer should be placed in the 13-liter spare wheel well. The installation requires appropriate wiring, taking into account the impedance versions (2 Ohm or 4 Ohm) and the suitable amplifier power. A professional installation ensures that all parameters, such as the maximum excursion (Xmax of +/-15 mm), are efficiently utilized to unleash the full capacity of the subwoofer.

How does the SPL value of the ARC Audio ARC8 affect the bass level in the Audi A4 B9?

The sound pressure level (SPL) of the ARC Audio ARC8 Subwoofer is 85 dB/1W/1m, which plays a significant role in determining the perceived volume level in the Audi A4 B9. A higher SPL value means more efficient sound production, requiring less electrical energy to achieve a certain volume level. Especially if you enjoy listening to loud music, the subwoofer ensures powerful bass tones without distortion. This is particularly advantageous in a vehicle like the Audi A4 B9, where powerful and clear bass reproduction significantly enhances the listening experience.

What are the advantages of the 12mm multiplex construction in the ARC Audio ARC8?

The 12mm multiplex construction in the ARC Audio ARC8 offers stability and robustness, minimizing resonances and improving bass performance. This design ensures that the Subwoofer withstands strong bass vibrations and that sound quality is not compromised even at high volumes. Covered in black felt, it aesthetically fits into the interior of an Audi A4 B9. The use of multiplex instead of conventional materials enhances resistance to moisture and temperature fluctuations, increasing the longevity of the Subwoofer and delivering consistent sound.

How do the impedance values of the ARC Audio ARC8 affect sound quality?

The impedance values of the ARC Audio ARC8, available as S1 / S2 / S4 / S8 / D2 / D4, offer versatile adjustment options for different amplifier configurations. The Re-value (electrical resistance) of 1.95 Ohm and 7.8 Ohm in the variants shows how resistance affects current flow, which in turn determines the efficiency and volume of the Subwoofer. A lower Ohm value (e.g., 2 Ohm) allows for drawing more power from the amplifier, while a higher value (e.g., 8 Ohm) means a gentler load. Therefore, the right choice between D2 and D4 can influence the sound quality and efficiency of playback in your Audi A4 B9.

What technical features make the ARC Audio ARC8 suitable for deep bass?

The ARC Audio ARC8 Subwoofer is equipped with a frequency range of 24.7 Hz up to higher frequencies, making it ideal for producing deep bass. The Subwoofer utilizes a large diaphragm area of 231 cm² (Sd) and the volume of the spare wheel well to ensure rich low-frequency reproduction. An Xmax of +/-15 mm means that the diaphragm has enough freedom of movement for deep frequencies to produce clear tones even at high volume. These attributes make the ARC8 perfect for bass lovers who want to enjoy deep, full sound in their Audi A4 B9.
