Pair of DS18 ZXI8.2D 8" High Excursion Subwoofers – 2400W Max Total, Dual 2-OhmThis package includes a pair of DS18 ZXI8.2D monster 8-inch high-excursion subwoofers engineered for bassheads who demand serious low-end authority but are working with tighter installation spaces. Designed to completely dominate the compact subwoofer category, the ZXI series bridges the gap between heavy-hitting SPL performance and premium sound quality. These subwoofers are built around highly efficient 2-inch high-temperature black aluminum voice coils that absorb and dissipate heat flawlessly. This allows the duo to handle a massive combined 1200 Watts RMS (2400 Watts Peak) without breaking a sweat, guaranteeing crisp, distortion-free bass during extended, high-volume jam sessions.
To generate competition-level air movement from 8-inch cone areas, each ZXI8.2D is equipped with an oversized 104-ounce quad-stacked ferrite magnet motor structure. This immense magnetic force provides absolute control over the rugged non-pressed paper cones, which are tethered to thick, high-excursion foam surrounds. This combination ensures maximal one-way linear travel (Xmax) to physically punch the air and deliver true, physical bass response down to 25Hz. Housed in rock-solid, custom sandblasted black aluminum baskets, this pair of DS18 ZXI8.2Ds provides relentless, high-fidelity bass for custom trucks, under-seat enclosures, and daily drivers. With their Dual 2-Ohm configurations, wiring them together offers the perfect flexibility to drop the system down to a highly efficient 2-Ohm or 0.5-Ohm final load.

A Game Changer for Sensitive Skin
I use this serum every single day, and it has become one of the most important products in my skincare routine. I have very sensitive skin and cannot tolerate stronger active ingredients such as retinol or high-strength acids, so finding something effective but gentle has been incredibly important.
This serum has helped calm redness, reduce inflammation, and noticeably improve my skin’s overall appearance and comfort. After dealing with a prolonged inflammatory skin condition, this product made a significant difference and helped restore my skin barrier.
The formula feels soothing, hydrating, and non-irritating. If you have sensitive or reactive skin and are looking for a gentle product to help with redness and uneven texture, I highly recommend giving this serum a try.
Photos attached: The green bottle is the product and the second photo includes my favorite additions.

Perfect for Acne-Prone Skin!
This serum has honestly been a great addition to my routine for redness and post-acne marks. The texture is lightweight, hydrating, and doesn’t feel sticky or heavy on my oily/acne-prone skin.
I have sensitive skin with a focus on barrier protection, and this didn’t irritate my skin at all. It layers beautifully with the rest of my skincare and leaves my skin looking calmer and smoother over time. AND, it doesn’t have a smell!!
Definitely one of my favorite azelaic acid serums I’ve tried.

6-Month Update: Still a staple for sensitive, acne-prone skin
Size: 3.38 Fl Oz (Pack of 1), Size: 3.38 Fl Oz (Pack of 1)
I originally reviewed this ampoule when I first started using it, and now after about six months of consistent use (morning and night), I feel confident giving a more long-term update.
I have sensitive, acne-prone, combination skin, and this has remained one of the most reliable products in my routine. The texture is still one of my favorite things about it — very lightweight, absorbs quickly, and layers well under moisturizer and sunscreen without pilling.
Over time, I’ve noticed:
Less visible redness
More balanced oil production in my T-zone
Fewer irritation flare-ups when introducing new products
No clogged pores or breakouts from this formula
It doesn’t feel heavy or sticky, even in humid weather. I’ve continued repurchasing and even keep it on subscription because it consistently performs without causing sensitivity.
If you’re looking for a gentle, soothing centella product that works well for long-term barrier support, this has proven to be a dependable option in my experience.

Healed my barrier so fast
Size: 3.38 Fl Oz (Pack of 1)
I received this ampoule yesterday and I'm already leaving a 5 star review after 2 uses because it just worked so well. I bought it because I've recently incorporated the Timeless 20% Vitamin C into my routine and that + my tretinoin made my skin drier than I've ever felt it before, even gently swiping a cotton pad with micellar would sting on some parts of my face. As soon as this ampoule arrived I applied it to clean skin and layered squalane on top (my moisturizer was burning as well.) This product did not sting my face AT ALL. It instead felt immediately soothing and hydrating. When I woke up this morning almost all of my redness was gone, my skin didn't feel tight or irritated, and my skin tone looked so even and glowy. I never thought a product, especially such a simply formulated one, could heal my barrier so quickly but that's exactly what it did and I can already tell it's a repeat buy. If you have redness prone sensitive skin and/or you use several high strength actives, this ampoule is a must have and it might be the key for anyone struggling to tolerate high strength retinoids. I got the largest size bottle for $15 on sale and it's seriously one of the most affordable and effective skincare products I've ever had in my routine.

Safe, Lightweight, Hydrating – Perfect for sensitive, super oily, acne-prone skin
Size: 1.85 Fl Oz (Pack of 1), Size: 1.85 Fl Oz (Pack of 1)
I care most about the ingredients, and this Madagascar Centella Ampule is excellent — all the ingredients are safe, with no potential harm to your health, and it’s Yuka app approved with a 100/100 safety score. I feel confident using it on my sensitive, super oily, acne-prone skin.
It’s super lightweight, absorbs quickly, and is not sticky at all — after applying, you just feel comfortable hydration. Even after a few hours, my skin doesn’t get oily, unlike some other serums I’ve used. It helps calm my skin and restore the barrier, which is perfect for my skin type. Even when I have acne wounds, it doesn’t irritate or sting — it’s extremely gentle. For sensitive, super oily, acne-prone skin like mine, it works wonderfully.
Living in Utah, one of the driest states in the U.S., this serum keeps my skin hydrated even in very dry conditions, and a little goes a long way — 1–1.5 drops cover my face and neck. Using more can make my skin slightly oily, so just the right amount works perfectly. For someone with dry skin, results may differ, but for my skin type, it works beautifully.
It’s also super affordable, and I’m glad it’s available on Amazon, with occasional great deals at Costco. I appreciate that it’s accessible at this price because this serum helps my skin a lot — very gentle on my acne-prone, sensitive, super oily skin.
The serum is super easy to apply with the dropper, which keeps other things from getting into the bottle — it’s perfect for easy, hygienic application. Just note that the bottle is glass, so be careful — it may break if dropped.
I’ve only been using it for three weeks, but it’s already a staple. I currently use one bottle, and the other two are extra for long-term use, especially since I got them on a great deal. This is now my main hydration serum, and I’ll update after longer use if needed.
