About This 4000 Watt American Bass Amp

The D-class, 1 Ohm Stable, 4000 Watt American Bass Amp that you can find at the previous link is a durable design that delivers serious volume and audio quality while remaining compact enough to fit into tight spaces.

This American Bass amp features a full metal-oxide-semiconductor field-effect transistor, or full-MOSFET design that improves audio quality, minimizes distortion, and protects the internal electrical components of the speaker.

These speakers also feature LPF and HPF crossover, which are two crossover networks that enable filters for specific frequencies to pass over onto the driver (or not) improving sound quality.

These speakers also offer “adjustable bass boosting” capabilities, enabling you the increase low-end frequency to pump the bass up.

They’re also built to offer long-lasting reliability, and feature protections against overheating as well as both high and low voltage.

Inline fuses are required for installation (and they’re not included) but the compact size of this American Bass amp is a bonus; they’re only 14.25”x6”x.2.25”, making them ideal for mounting in inconspicuous, space-restricted locations.

As far as specifications, the D-Class 1 Ohm Stable 4000 Watt American Bass Amp offers:

• Input: .2-5V
• Frequency response: 10-220Hz
• Subsonic filter: 10-50Hz
• Max wattage: 4000W
• S/N ratio: >80dB
• RoHS Compliance

This American Bass amp is also configurable with an optional bass knob (not included) and the suggested wire gauge is 0 AWG.

Improving the Efficiency of an Automotive Amplifier

The first thing you will need to look out for to determine if your amplifier needs maintenance or could use some help is to listen for deterioration. If you start to notice a degradation in audio quality, you may need to replace components or administer other routine maintenance.

But there are some other tricks you can follow to improve sound quality, without the need to change parts or tinker. Here are some of the best suggestions.

One of the most important things you can do is “run the speakers” in. Think of running speakers in like breaking in a pair of boots. Out of the box, a speaker isn’t going to sound as good as it will after it’s had a few hours of playing. When you first get your amplifier installed, run it as many hours as you can to “run it in,” and improve sound quality. Trust us, box-fresh speakers and amplifiers don’t sound as they will after they’ve been run for a few weeks.

This may not apply to all amplifiers/speakers, but if yours has a display, consider turning it off to boost sound quality. The reason for this is that audio displays are a source of “electrical noise” that can adversely impact the quality of sound output. The bigger and brighter the display, more than likely, the bigger an offender it is.

Also, be sure to install your amplifier and speakers on proper supports that minimize vibrations that compete with the sound quality. A quality speaker or bass box will do the trick, as these are specifically designed to support the speakers, minimize vibrations, and mitigate interference, but here’s a trick: partially inflate a bike inner tube, then place it underneath the amp/speakers. It should be very soft, sort of like a partially inflated air mattress. This will help absorb vibrations and may improve sound quality.

Keeping Your Car & Truck Amps in Top Shape

If you put good money into an automotive amplifier like one of these 4000 watt American Bass amps, you’ll want to make sure the investment lasts. They’re built tough and engineered to last for the long haul, but you’ll still want to make sure you care for them properly.

Two of the best considerations for routine automotive audio amplifier care are to keep them clean and well-ventilated. Over time, dust and other debris can collect on an amplifier and cause overheating which will damage it; this is the same reason it must be properly ventilated. Purpose-built speaker enclosures will help protect them from dust and keep them well-ventilated, but you should still clean them from time to time.

If you use the wrong cables, or if there are weak connections, the sound quality can suffer. Ensure you are using high-quality cables and that the connections are secure.

Also, make sure you are using a quality power supply, one that is free from spikes and voltage drops, as these can damage your speakers.

Last but not least, and though it might seem obvious, keep stuff from banging into your speakers/amplifiers. If they’re in your trunk or bed, it’s not a good idea to let your stuff (whatever it is) contact your speakers. This is another area in which a speaker or sub box can come in handy as it will protect them, but you should still conscientiously shield them from incidental contact.
