Alphasonik AS12DF 12" 1500 Watts 4-Ohm Down Fire Shallow Mount Flat Enclosed Sub woofer for Tight Spaces in Cars and Trucks, Slim Thin Loaded Subwoofer Air Tight Sealed Bass Enclosure

I waited a year to write this review in order to be fair in my assessment and to also be able to speak to the durability of the product. I installed this sub in a Jeep Wrangler and powered it with a Rockford 5-channel amp that is also powering four 6.5s. I didn't want to take up a lot of space in the cargo area with a huge box and I really just wanted to round out the low end; I listen to a lot of classic rock and reggae so I was not looking to shake any windows since only about 10% of what I play falls within the rap or hip-hop genres. Initially, I was pretty underwhelmed with this sub - the first couple weeks gave me average performance at best and I did also experiment with some bass-heavy R&B just to see how it would perform. With the R&B, it produced a dull thud-like sound and with the classic rock, it really didn't sound very good when turned up loud enough to make a difference. But over the next month or so, it started to loosen up and sound more musical than noisy, and after about 3 months of moderate use, I became very happy with it. Again, I was not looking for club-quality bass, I just wanted to add some depth. That being said, it also performs very well now when I pop in some rap or hip-hop. Not a competition sub by any means, but I find myself needing to turn down the bass level for these genres. When the doors and top are off the Jeep, I'll adjust the bass knob a little higher and it is sounds great, even above the wind noise.My bottom line with this sub is that it is an excellent choice for anyone who wants to add nice tone to the lower end of the spectrum. It takes up a surprisingly small amount of space for a 10-inch, and i feel it is a bargain at this price point. The construction of the box itself is also very solid; it's had sports equipment, lawn supplies and such thrown on it, placed on it, been covered with it and a year later, it's no worse off than the day I got it. If you give it time to work itself in, you'll be happy.

Great sound for the price. It's super convenient and very small for the actual sound that it comes off. Lots of power for the size. Quality build is also very sturdy. Best feature is that the amp is already in it.

I like how compact and powerful this 10” powered subwoofer is . I felt that my non Bose stereo on my 2019 Chevy Silverado needed a little more bass and this helped it so much . Very happy with my purchase , well made and very easy install with the t harness and lots of YouTube videos on how to install. I recommend it to anyone who is looking for a nice powerful sub to enhance your stock stereo!!!

And it doesn't take up too much space in the back.

Perfect for a sedan and sound quality isn’t bad at all would highly recommend have had it for over 6 months now and haven’t had any issue what so ever…install was easy if you know a little about wiring

I have it hooked up to a 500w max output Sony amp. It sounded pretty good for a couple of weeks, but it was obvious to me that the little Sony amp was as much as this speaker would suffer from day one.Right after the return window closed it started sounding terrible! Sounds like the box is coming apart or something. At first I thought something in the car was rattling but it's the speaker itself.Contacted their support and will update if they respond.

Very good sub for the money! Sounds good and low profile.

easy install, no fish up in here, smells like awesome bass fill. If you want superboom you might want a bigger box...or 4 or them ;)cheap and very effective, best bang for my buck for sure. loved the old school alphasonic and ...still do :)
