Autotek Street Machine SM46CX 4x6" 2-Way Coaxial Speakers – 200 WattsThe Autotek SM46CX 4x6-inch coaxial speakers are high-performance replacements designed to breathe new life into vehicles with rectangular factory speaker locations. Part of the Street Machine series, these speakers utilize Alpha-Cellulose poly cones that deliver a rich, mid-bass punch and textured midrange, far exceeding the performance of standard factory paper drivers. High frequencies are handled by Neo Mylar soft dome tweeters, which provide crystal-clear detail while maintaining a smooth, non-fatiguing sound profile.

Recommend, sturdy, good hardware, easy hang
Color: Navy Blue With Silver Handle, Size: 24x30
This is quite nice. It is sturdier than I expected. The way it hangs is really nice, it will be easy to lift off to paint the wall. The hinges are nice and soft close. One bad thing is it is quite smelly right away. I keep forgetting to keep the doors open to air that out so every time I open it I am still hit with the bad chemical smell. There were also sticky areas around the edges from the packaging that I had to work hard to get off and still don’t have quite all of it off.

Exceptional product !
Color: Expresso With Silver Handle, Size: 24x30
EXCEPTIONAL is every way ! Couple of tips included.
1) Packaging. Perfect. Used high quality EPS that didn't shred and make a mess when you unpacked it. Every piece was wrapped and corner capped to prevent any damage. EVERY RTA product should be packaged this way.
2) Assembly: Easy. Every piece was clearly labeled, instructions were easy to follow. NOTE: This cabinet used a "beveled bar" type product hanger which makes it SOOOO easy. Just make sure the bar is level and centered where you want it to go, and viola! Hint: For sheetrock or drywall install, I used Hilti (toggle type) screws, not the included anchors. Hilti's are easier and more stable. If you are going into stud, obviously you can screw directly into them, but otherwise, use Hitli (toggle type). I also put a couple of small rubber bumpers on the back, at bottom of unit to help prevent it from moving around during use. Also, I'll use a couple of felt door bumpers on inside of doors as well.
2) Finish Quality: Perfect. I used "goof off" to remove a couple of stickers residue and it didn't affect the finish at all. Don't know what this finish is, BUT it seems Extremely durable, but check any cleaning agent using the mount bar as that is not seen.
3) Overall: I'd been hesitating to install this for non related reasons, but when I saw the beveled mount bar type hanger, figured I give it a shot. It was SO easy. The only thing is I bought the espresso finish, and was thinking it may have a wood grain look, but it's smooth, almost appears like a powder coat type finish, but am extremely happy with the product and highly recommend it.

solid, quality cabinet and the best wall mounting system I have seen in a while
Color: Black With Silver Handle, Size: 24x30
It is a quality cabinet and has the best wall mounting system I have seen in a long time. The cabinet is solid and sturdy and was easy to put together. I can already see it lasting a long time in our bathroom. It is a bit heavy and you may need a second person to assist with mounting.
