Alphasonik AS8DF 8 inch 600 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

Perfect match for my trunk, the performance of the sub is magical thoughIt needed a few days to break the sub.So far its a good one.

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.

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

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

We bought a AS12DF 12" under seat sub on 8-15-2024 and it played well for 2 months. The sub box is well built, but the driver is cheap and vibrates loudly intermittently. This is a defect of the speaker. We have tried to email support and call, no response. Buyer beware as once the return window closes on Amazon, it seems like your stuck with it. They claim to have a 1 year warranty, but if they don't respond what good is it?

Fit under the back seat of my 2020 1500 crew cab. Sounded great and could feel the bass from the driver's seat. Had to return it because of a terrible fish smell.

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.
