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.

Room Divider That Gives Instant “This Is a Separate Space Now” Energy
Size: 3 Panel 12FT W
The Siebwin 3 Panel Folding Privacy Screen is surprisingly effective at changing the feel of a room without requiring construction, commitment, or somebody yelling about load bearing walls. The 12 foot width gives a substantial amount of coverage, making it useful for creating privacy, dividing open areas, blocking visual clutter, or setting up temporary sections within larger rooms. This saved us a ton of time and money in our new studio and enabled us to create a kitchen and office in one room. The wider feet make a huge difference because flimsy room dividers that collapse every time someone exhales too aggressively are deeply annoying. This one feels more stable and grounded once positioned. The folding design makes it easy to move around or adjust depending on the space, and it folds down relatively compactly when not in use. It is basically the introvert curtain wall of dreams. The material has a clean, neutral look that blends well into different room styles without screaming “temporary office cubicle panic.” It works well for apartments, studios, shared spaces, dressing areas, or simply hiding the mountain of chaos you swear you are going to organize tomorrow. Practical, portable, and refreshingly easy to use without turning setup into a three hour emotional event.

It's 2 panels holding 1 big privacy screen. Can't use as 2 separate 4' panels, but works great.
Size: 2 Panel 8FT W
This 2 panel privacy screen works well. Assembly was very straight forward, with easily labeled tubes. My son and I had it together in about 10 minutes, which was probably 3 minutes of me telling him to quit playing around and hand me the parts. It feels very sturdy, not likely to fall over or anything. The material fits well, with the Velcro being very strong. Measurements are all very accurate, with all pieces attaching properly. We have a similar privacy screen at work that we have to try and stretch out because the top and bottom Velcro doesn't fit quite right... this model does not have any issues though. The material is thin and light weight, but solid black so that you can't see anything through or behind it. I definitely think it's a great deal for the money. What I think would have given it 5 stars though, is if you had 2 totally separate 4' panels instead of 2 panels with one big screen. It really wouldn't cost any extra to make it so that the screen was in 2 pieces and you could use it as 2 separate panels instead of having to use it as one big panel. It says 2 panel folding privacy screens, but it's really one big one that folds in the middle.

Worth the investment
Size: 1 Panel, Size: 1 Panel
I had to order this in an emergency. To put it in brief words, I live in a two level studio unit. My bedroom TV fell backwards off the bureau accidentally and down the stairs to its demise. Putting this together was no problem, instructions were thorough and easy. It came with several bars that connected together smoothly and an Allen key for the brackets and screws for the feet. I did one less horizontal bar on top and bottom so it could fit, which was great because with all of them on it was too long. However I ran into the difficulty of the horizontal bars popping out of the brackets during the last stages, but eventually got it done. I was also looking for a specific type of divider where I could adjust the feet so I could tuck it in between the dresser and banister. Glad I made this purchase.

You Get What You Pay For! A Piece Of Junk!
Size: 1 Panel
Flimsy and a piece of junk. Don’t waste your money. Assembly is a pain because it is so flimsy. Divider is thin. You can see right through it. Very wobbly.

Instructions are useless
Size: 1 Panel
The instructions are poorly written and not very helpful. The divider itself is easy to assemble, and honestly, it would’ve been quicker if I had skipped the directions altogether. Once put together, though, it works as intended.
