DAWN OF A NEW ERA

The newly launched RIOT series amplifiers are meticulously engineered to deliver features and performance typically associated with higher-end models.

The innovative RGB LED functionality showcases a range of audio-responsive patterns, and should you prefer a minimalist aesthetic, the lights can be effortlessly deactivated, allowing the pristine white PCB layout to shine.

Due to its compact and thoughtfully engineered design, this versatile 4-channel amplifier can be effortlessly installed in nearly any space.

The 1800.4 RGB and its 1-channel sibling, the 2500 RGB, were designed to offer great value for price-conscious buyers. All the flashy features and sleek designs are certainly a plus. However, that is merely the icing on the cake.

The truly impressive aspect is the real-world power. Even though the RIOT 1800.4 RGB is rated at 4 x 450 watts at 2 ohms, 14.4v, real-world tests and lab evaluations conducted on amp dynos have far exceeded that. The true RMS power measured was over 4 x 600 watts! That’s more than 33% beyond its rating; even in bridge mode at 4 ohms, this amplifier excelled, delivering 2 x 1300 watts. Given the compact dimensions, the power output, and the features offered, the RIOT 1800.4 RGB can power any system as a full-frequency loudspeaker amplifier. Even as a tri-mode amplifier, where 2 channels run the speakers and the remaining 2 channels are connected to subwoofers, you will not be disappointed by its performance.

If you want to install it in newer vehicles without a switched remote signal, the RIOT RGB amplifiers feature high-level inputs and come with all the necessary wiring. We have even added a clip light sensor to this amplifier so you can enjoy your music without the added distortion.

I absolutely love the Saltair line of products!
Scent: Sandalwood
I used the body wash at a friend's house and fell in love, especially with the Santal Bloom scent! This body oil is just so amazing and feels so silky and soft. It's especially effective if you use it right out of the shower. It adds a beautiful glow and I even use a little in my hair. It's quite concentrated so a little goes a long way. I have even mixed it into my favorite coconut oil and it mixes beautifully. Don't sleep on this line!

Smells great
Scent: Golden Hour
Love this, my favorite scent from this line. Very subtle glitter so I still feel age appropriate. It’s an oil soy skin does feel oily for a little bit afterwards until it soaks in. It has lasted me quite awhile so I do feel it’s good value for the money. Have reordered a few times.

Great Glow and Scent, But Fades Quickly and Runs Out Fast
Scent: Vanilla
The Saltair Shimmering Body Oil in Salt Water Vanilla is a beautiful product. The only 3 reasons I don’t give it 5 stars are because: 1. The shimmer is not very long-lasting. When I apply it before bed, most of the shimmer effect is completely gone and absorbed by my sheets by the morning. I assume pants and leggings would absorb it in the same way, but I’ve only ever worn shorts after applications during the day, and even then, the shimmer seems to fade after 4–6 hours. 2. I have to apply a lot of oil to achieve the amount of shimmer I desire. It averages about 20–25 pumps per use. 3. The 4-ounce bottle size, combined with needing a lot of product for each application, means I’m going to run out of it pretty quickly. Here’s why I like this product: 1. The glow: If you’re looking for a subtle glow and a light shimmer effect, this oil is perfect for you; apply it before a night out, while wearing a swimsuit, or when going to the gym in your favorite workout set for a beautiful gleam. 2. The scent: It’s a divine, warm mix of sweet and spicy notes. It smells like vanilla, amber, and toasted marshmallow. It pairs really nicely with tropical, woodsy, sweet, or spicy perfumes—it’s very versatile. 3. Consistency and absorption: The oil absorbs nicely and has a light, runny consistency. Because it’s a dry oil, it isn’t too thick, nor does it leave a sticky feeling on the skin. 4. How my skin feels: I’ve used this oil 4 nights in a row, and every single morning I wake up, my skin feels so soft and smooth, with no residual stickiness or residue left behind.

Saltair shimmer
Scent: Sandalwood
Nice on the body. Easy to apply. I use it with my lotion for an all over glowy shimmer. It will be very nice in the summer. Nice scent, no irritation.

Buy it you won’t be disappointed
Scent: Sandalwood
I love it already and I haven’t applied it directly to my full body after a shower as instructed but from what I did apply it’s whatever it says it is . It eats down ok, skin softness, moisturizing , the shimmer is just enough , the scent is soft and smells incredibly great. Smells like a fresh shower lol it’s not thick consistency at all and just the right amount of oiliness to add shine to the body. I can’t wait to use this product fully .
