MTX Audio FMUST05BK12-TN ThunderForm Loaded 12" Subwoofer Enclosure – 2005-2014 Ford Mustang (Coupe)FITMENT NOTE: Fits 2005-2014 Ford Mustang Coupe (S197 Platform). Does NOT fit Convertible models, the Shaker 1000 factory system, or 2015-Up (S550) models.
The MTX FMUST05BK12-TN is a custom-engineered, vehicle-specific subwoofer solution designed to add deep, hard-hitting bass to your 2005–2014 Ford Mustang without taking over your trunk. This "Loaded" version features a high-output 12-inch Terminator series subwoofer pre-installed in a rotationally molded high-density polyethylene (HDPE) enclosure. By utilizing the passenger-side rear corner of the trunk, the FMUST05BK12-TN provides a massive audio upgrade while leaving the main cargo area open for your gear. Because it is non-amplified, this enclosure is the perfect choice for Mustang owners who want to use a dedicated external amplifier to drive their system for maximum performance and customization.

Absolutely love this pillow!
Color: White, Size: Queen(Pack of 2), Color: White, Size: Queen(Pack of 2)
The pillow was very well packaged and extremely easy to open. As soon as I took it out of the package, it immediately expanded and became fluffy within seconds. I was honestly surprised at how quickly it regained its full shape.
The pillow feels very soft and comfortable, but it still provides great medium-firm support. It has excellent resilience and bounces back quickly after being pressed, so it never feels flat. I’ve been using it both for sleeping and for supporting my lower back when sitting, and it works great in both situations！
I also really like the embroidered logo, which looks very delicate and well made, it adds a nice premium touch to the pillow. It would also make a great gift for family or friends.

Heavenly soft and comfortable.
Color: White, Size: King(Pack of 2)
This is a great pillow. I bought 2 king size for my daughter. They are so soft but have some heft to them. They don't squish flat. They plump up so nice. She said like having a cloud for a pillow. I love Serta. They have always been good. Buy it and sleep like you're in heaven.

Decent
Color: White, Size: Queen(Pack of 2)
They are only used as a backup pillow for my special pillows I use since I have pillows with holes in the middle for my earrings. I also use them for when I lean on my headboard to watch tv. I like them they are squishy. Kind of expensive I feel like but not terrible

Just perfect. Well made, No Issues Just one perfect sleep zzzzzzzzzzz😴
Color: White, Size: Queen (Pack of 2)
I had down pillows, and foam pillows, and other synthetic pillows etc and some were ok and others were not. I cannot get a great nights sleep if I am constantly having to adjust my pillow during the night. I ordered these pillows as I sleep on my side mostly but sometimes on my back. When they arrived I followed the directions (as they are in a vacuum pack) and only takes a few minutes for them to acclimate. Then put pillow cases on them and off to bed. I had the BEST sleep I have had in YEARS !!!!! The pillows are great. They keep your head comfortable and cool (No Sweating) and super comfortable. The only issue is after a perfect nights sleep, I find I really do not want to get out of bed in the morning..One great thing, is I am retired so I really do not have to get up out of bed until I want to 😴😳. The pillows are well made and feel like expensive down filled pillows but softer. I am VERY satisfied with the pillows. I just wish I would have found these pillows years ago. But now I have them and the perfect sleep that they provide. Dr Dave
