As a first step, you will want to ensure that the radio settings are flat or at zero. With a properly tuned system, you should never have to use "bass boost" or "loudness". Depending on the model of your radio, you may be able to fine-tune the subwoofer level. You should adjust your system so that it is loud without causing distortion or popping. Take your time to listen carefully to the sound (produced by the subwoofers). When you have determined your optimal level, reduce the settings (gain) by half. For example, if you are at half gain, you should drop it to a quarter gain.

The following setting is your "break in" setting. For the first 24 to 36 hours of actual play time with your new subwoofers, you should maintain these settings. A weekly amount of regular listening to music in a vehicle that is driven on a daily basis is usually sufficient. After the initial 24 to 36 hours, you may return your system to its original settings. Having broken in your subwoofer(s), you are now ready to use them.

NOTE: This is the simplest explanation of only one method for breaking in your new Audiopipe subwoofers. Although there are more involved methods that require specialized tools, this method is a great place to start. If you have any questions regarding methods or other topics, please do not hesitate to contact us.

Voice coils are not superior to one another. It is important to note that the coil configuration determines the impedance (or resistance) an amplifier will experience when it is wired to the subwoofers. For selecting the coil configuration that will work best for your setup, you should take into account the capabilities of your amplifier and the number of subwoofers you will be connecting to it

Confirm that the RCA cables and speaker wires are connected securely. Check the amp's gain and crossover settings. Test with another speaker to ensure the output channel is not faulty.

Match the RMS power and impedance ratings. For best results, your amplifier's RMS output should be close to your subwoofer's RMS rating per channel.

Excessive power or distortion causes heat buildup. Verify impedance, avoid clipping, and ensure adequate airflow around the sub.

Play at moderate volume for 10–15 hours to allow the suspension to loosen for optimal performance.

We recommend having the gain tuned with a multimeter to ensure the correct power output or an oscilloscope to ensure that the amplifier is not outputting any distortion or clipping to the subwoofers. We recommend between 40-125hz LPF for most of our subwoofers and a subsonic filter set to 25-35hz while Bass EQ is set to 0dB.

Clipping is a waveform distortion that occurs when an amplifier is overdriven and attempts to deliver a current beyond its maximum capability.

Both positive terminals connect to one positive terminal on the amplifier board.

Both negative terminals connect to one negative terminal on the amplifier board

Using this design function, multiple subwoofers can be driven by a single amplifier.

Choose an amplifier that can output the correct RMS rating for the speakers you have.

It is important to note that all amplifiers have a maximum output power, but RMS refers to the constant power that is delivered to the speaker

Audiopipe amplifiers are not stable below 1 ohm. Running your amplifier below 1 ohm is against manufacturer specifications and can result in the voiding of your warranty.

Yes, we are looking forward to taking care of all our customers' repair needs. It is our policy to service Audiopipe's amplifiers whenever possible at our facility. If you require service outside of the warranty period, you may contact Audiopipe for a quote on the repair, so please do not hesitate to contact us.

• The Maximum Musical Consumption (MAX) refers to the amount of power an amplifier draws during typical music playback, including dynamic peaks, but not continuous tone testing. It provides a more accurate representation of how your amplifier performs under everyday listening conditions.
• The maximum sinusoidal consumption (RMS), on the other hand, represents the continuous power draw when a constant sine wave is used to drive the amplifier. In practice, it is typically higher than what is seen in normal use since it is more of a laboratory measurement.

For system design and power planning, use the Maximum Musical Consumption figure. It gives you a more realistic expectation of how much current your amplifier will demand during actual playback — especially for car or motorcycle audio setups where electrical limits matter.

This occurs because any Class D (digital) amplifier has a power supply with high-frequency switching, which can interfere with long-range FM signals. To avoid interference, prioritize local radio stations because their signals are stronger

Another alternative is to mount the digital amplifier independently from the initial vehicle wiring, with the powering cables (positive) taken straight from the battery and a well-shielded RCA (as short as possible) to prevent both resulting in a kind of antenna.

Noise that interferes with the FM signal is common on all class D amplifiers, regardless of manufacturer. Depending on the model, high-frequency switching from the amplifier's power supply leads to the development of more reliable amplifiers with lower consumption and higher power.

Here are a few tips to help you reduce this kind of interruption even further:

• Remove all contact between the amplifier body and the car chassis;
• Lock the power cables and pull them straight from the battery to the low power amplifier (this benefits the FM signal);
• Determine the best location to attach the amp inside the car, and if it's RCA, use the shortest cable possible with high-quality shielding.
• Make good use of the high-performance CD player and antennas. This removes the possibility of FM signal interruption.
• Braiding the output wires to the speakers with the aim of canceling out high frequencies will also help.

Make sure your speaker wires are properly connected and that the polarity (+/-) is correct. It is important to ensure that your speakers' impedance matches the amp's rated load. Wires that are loose or frayed can also lead to connection failures.

The amp may be overheating, shorting, or overloaded. Check for damaged speaker wires, proper grounding, and correct impedance. Let the amp cool down before restarting.

Use at least 8-gauge wire for smaller amps and 4-gauge or thicker for high-power amps. Always check your amplifier's manual for recommendations. For best performance we highly suggest using 100% copper wire.

If your system distorts at high volumes, your amp might be underpowered. If your subwoofer or speaker overheats or fails, it may be overpowered.

Check RCA input connections, speaker wires, and gain settings. Make sure the amp's “input mode” and “crossover” switches are correct.

Your amplifier might be drawing more current than available. Use proper gauge power cable and check your battery connections/alternator health.

Start with all gains at minimum, then adjust slowly while listening for distortion. Use a test tone or tuning app for precision.

It is important to note that in sound waves, the sides of clipped signals are vertical. This means that the signal will try to move the subwoofer cone as quickly as possible from front to back. There is nothing that can move that fast: so, either the subwoofer will tear itself apart or the flapping cone will wobble just enough to cause the coil to jam in the voice coil gap

Yes! Many Audiopipe loudspeakers, like the APMB-CX Series, are designed for motorcycle applications.

2-ohm speakers draw more power from the amplifier for louder output, while 4-ohm speakers offer cleaner sound with less strain on your amp. Keep in mind that most of our bass amplifiers will be stable down to 1 ohm.

This may be the result of a damaged coil, loose wiring, or an overpowered signal. The volume should be lowered, and the connections should be inspected.

Use a multimeter to check resistance. A healthy 4-ohm speaker should measure around 3.5–4.5 ohms. No reading means it's blown.

For motorcycles and compact vehicles, APMB-CX series offers a coaxial design with specially designed components that provide protection from harsh environmental conditions such as water and dust. For Pro Audio applications, the APMB-8 Series delivers higher power with a specially designed paper cone and is usually housed in diecast baskets

It's not recommended. Mixing can cause imbalance and stress your amplifier. Match ratings for best results.

Currently, Audiopipe does not design custom enclosures. This includes making any recommendations on 4th and 6th order band pass enclosures. We do however have some detailed cut lists for generic enclosures that are built to spec for multiple combinations of our subwoofers. We would be happy to assist in sending these free of charge to any customer: however, we are not able to make any modifications to them.

It is important when reviewing enclosures for fit with your subwoofer(s) to consider a few basic specifications

Audiopipe knows the importance of finding/building a great enclosure to unleash the power of your subwoofer, so we proudly display all our recommendations for our subwoofers and their enclosure specifications on each product's page.

Audiopipe is proud to offer a variety of prefabricated enclosures for those individuals who are looking for an enclosure for their subwoofers.
