Welcome to our website! As we have the ability to list over one million items on our website (our selection changes all of the time), it is not feasible for a company our size to record and playback the descriptions on every item on our website. However, if you are an American with a disability we are here to help you. Please call our disability services phone line at (540) 786-2777 during regular business hours and one of our kind and friendly personal shoppers will help you navigate through our website, help conduct advanced searches, help you choose the item you are looking for with the specifications you are seeking, read you the specifications of any item and consult with you about the products themselves. There is no charge for the help of this personal shopper for any American with a disability. Finally, your personal shopper will explain our Privacy Policy and Terms of Service, and help you place an order if you so desire.

Image Feature

2 Ohm Stable

The lowest impedance accepted by this amplifier is 2 ohms. Amplifiers that are 2 ohms stable produce more power resulting in more volume. This amp can comfortably power speakers or subwoofers with all channel(s) being used at a load of 2 ohms.

Image Feature

Bridgeable

Bridging an amplifier means to combine channels of a multi-channel amplifier to get more power or flexibility out of it. For instance, on a 4 channel amp, channels 1 and 2 could be used normally for your speakers, and channels 3 and 4 can be bridged for more power to a single subwoofer. A 2 channel amp can also be bridged to power a single subwoofer.

Image Feature

Class A/B

Class A/B amplifiers have long been known for their ability to produce great quality sound while performing more efficiently than pure Class A amplifiers. We have developed a specific linear circuitry that further reduces distortion while increasing both sound quality and power output.

Image Feature

Fixed High Pass Filter

Fixed High-pass filter gives you the ability to filter the frequencies that pass through to the full range speakers from a fixed frequency point.

Image Feature

Fully Marinized

Fully Marinized is the term we use for our Marine and Outdoor products that are Weather Proof. We integrate high-tech, state-of-the-art waterproofing materials plus special UV coatings for plastic surfaces, coated circuit boards and connections to protect the product against the harsh outdoor elements and resist corrosion.

Image Feature

High and Low Level Inputs

An amplifier with both high-level and low-level inputs provides flexibility by allowing you to build an audio system using virtually any standard factory or aftermarket source unit. High-level (speaker level) inputs accept the signal from the speakers, while low-level (RCA) inputs accept the signal from the pre-amp outputs of the source unit.

Image Feature

MOSFET

MOSFET stands for Metal Oxide Semiconductor Field-Effect Transistor. MOSFETs are used either as a switch or to amplify a signal. MOSFETs are superior to other FETs, because they require less current to operate, which makes them better suited for car audio.

Image Feature

Protection

If the amplifier gets too hot, the thermal protection circuit turns the amp off and allows the amp to cool down before turning it back on. If a speaker fails causing an electrical short, the protection circuit will automatically cut the output and remain in that state until the short is resolved. These safety features give you peace of mind knowing the amplifier is constantly monitoring conditions to protect itself.

Image Feature

Subwoofer Level Control

The ability to boost or attenuate the sub level when an amp and subwoofer are connected to the subwoofer pre-amp output.

Image Feature

Switchable Input Sensitivity

Switchable Input Sensitivity gives you the freedom to connect the amp to any standard source unit and have peace of mind it will be within range to properly match the output of the source unit allowing you to use the volume controls on your source unit the way it was designed.

Image Feature

Variable Bass Boost

Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it.

Image Feature

Variable Gain Control

Variable Gain Control lets you balance the amps output with the speakers or subs the amp is driving. To much gain will lead to distortion and to little will lead to clipping.

Image Feature

Variable Low Pass Filter

Variable low-pass filter gives you control over the frequencies that pass through to the subwoofer.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
