Features You'll Love.

Experience unparalleled sound quality with compatibility for high-resolution audio sources, delivering rich detail, an expansive soundstage, and stunning realism. Engineered with high-performance operational amplifiers, the GM-DX104 minimizes noise in small-signal circuits to produce crystal-clear tones across a wide bandwidth. This compact amplifier also offers the flexibility to amplify 4, 3, or 2 speakers by bridging or not bridging the outputs, resulting in available power of 4x 45 watts RMS at 4 ohms or 90 watts RMS when bridged. Its compact, energy-efficient design and high-voltage compatibility ensure effortless installation in virtually any vehicle, making it the ultimate choice for audiophiles seeking exceptional performance and versatility.

Exceptional Sound Quality Beyond Its Size

Enjoy premium audio performance with the GM-DX104, designed with high-quality components for exceptional Hi-Res sound quality. Its Class FD amplifier circuit integrates a high-performance operational amplifier suitable for high-resolution audio sources, delivering superior audio fidelity and dynamics. Independent F/R channel circuits ensure precise adjustment for perfect optimization with your source, maximizing the signal-to-noise ratio of your audio system. The use of OFC (oxygen-free copper) cables improves electrical conduction while reducing the risk of corrosion and oxidation over the years, which is often associated with performance losses. All with one goal: to offer you an immersive listening experience.

Adaptable Installation for Any Vehicle

The compact design of the GM-DX104 eliminates the need for extra space, allowing for seamless installation in virtually any vehicle. Its small size ensures flexibility, making it easy to integrate into tight spaces without compromising functionality or performance. No need to worry about installation constraints—this amplifier fits wherever you need it.

Easy and Efficient Installation

In addition to its compact size, the GM-DX104's low current consumption (averaging only 1.6 amps) simplifies installation by eliminating the need for additional wiring to the engine compartment, significantly reducing installation time. Power can be easily supplied from the back of your navigation or car audio system. With the included RCA input and speaker line input cables, you can begin your installation immediately after purchase. Designed for user-friendly integration, this amplifier guarantees a hassle-free installation process for everyone.

High Voltage Compatibility for Versatile Applications

Engineered for compatibility with high voltage systems up to 16V, the GM-DX104 is an ideal solution for electric vehicles (EVs) and other advanced applications. Its low current consumption, averaging only 1.6 amps, ensures efficient operation without excessive power draw. The circuit design incorporates carefully selected components optimized to deliver reliable, stable audio performance and exceptional energy efficiency from 10.5V to 16V, making it an excellent choice for any vehicle equipped with an Auto Start/Stop feature.

High-Quality Affordable Design

To prevent poor bass performance in demanding situations, such as heavy bass content or dynamic range music, Pioneer designed a high-quality power supply to sustain constant power requirements. This design enhances audio performance by providing a better signal-to-noise ratio, improved audio dynamics, sustained bass when needed, and, most importantly, a more enjoyable ride in your car!

Hi-Res Certified

An optimal printed circuit board design reduces signal interference, improves channel separation, and provides better dynamics and lower distortion. Audio film capacitors and a low-impedance coil for the output filter are used to ensure excellent sound quality. Audio tuning based on the reproduction of the original audio source allows listeners to experience the difference in sound quality. With sound data that exceeds the volume of CD sound information, this amplifier reproduces outstanding audio quality from high-resolution audio sources, offering incredibly lifelike sound.

Gold Plated Terminals

These terminals maintain an accurate signal with increased electrical conductivity, prevent corrosion, and offer enhanced durability with excellent resistance to wear.

Pioneer’s TVC (Total Vibration Control)

Pioneer's TVC (Total Vibration Control) concept used in this amplifier not only increases the rigidity of the unit but also counteracts vibrations that affect sound quality at various points. The fixing points of the main board are optimized to completely suppress external vibrations and small vibrations caused by circuit parts. It adopts a heat sink structure that optimizes the position of large components, mounting screws, heat dissipation, and mechanical vibration suppression.

Very fun toy at a great price
Color: Monsieur Acorn - Large
My dog (an American Staffordshire Terrier) lovessss to chew and destroy things! We have literally gotten three of these because she loves them so much, and they last, too!! You get the first toy, which my dog rips open. I’m not sure exactly how long it takes for her to destroy it, maybe a few days to a week. Then another little toy (with a sad face lol) is revealed. She highly enjoys this one, as well! Finally, she rips the fabric off that and then a blue, spiky ball is revealed. She lovesss to chew on it and I think the bumps are a nice texture for her mouth. She is quite a strong chewer and the ball lasts a long time!! No toy lasts forever and I have found under dog toys are quite expensive and that’s no guarantee of how long it will actually last. But I am perfectly fine with spending ~$11 every once in a while for these toys because I know she loves them, and they are not immediately destroyed.

Would happily purchase again.
Color: Hedgehog
My powerchewer of a dog destroys plushies in 10 minutes and most other 'tough chew' toys don't last more than a day or two - at most. But he loves his hedgehog and hasn't managed to destroy it! Sure, it has a plethora of teeth marks, but it's in one piece and he hasn't managed to bite off any chunks (I was worried about the hedgies nose 😂). It stands up to his teeth and allows him to satisfy his need to gnaw & chew, safely.

Excellent, But Not Strong Enough
Color: Monsieur Acorn - Large
This has become the most engaged my dog has ever been with a toy. He chewed these acorns for an hour and a half STRAIGHT. Sadly, he was able to shred both acorns by this time. For dogs with a normal chewing and shredding amount, this toy would be perfect. However, for a super chewer like our dog (Lab/Malamute), it seems like we're going to need something stronger...
