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

Really filled in the low end on my system. Installed in a 2014 Raptor SCAB

I first bought the 8 inch Alphasonik sub for wife's Dodge Journey. She's not fussy with audio so I got her the 8" which I wasn't expecting to be earth shaking. It was small, the price was right and it got great reviews on Amazon. I was pleasantly surprised by the amount of punch from this little thing! I'm powering it with a JL Audio 250 watt mono amp. As a quasi-audiophile I wasn't looking for thunderous, muffled bass, but I wanted to fill out the bottom end with a faithful reproduction of the 50-100hz range. I loved the 8" sub so much that I ordered the 10" one for my Dodge Ram 1500--knowing that I'd love it. I'm powering that with a Pioneer 4 channel 4/3/2 amp. It hits a good bit harder than the 8" and I'm a satisfied customer! Above all this, the subs are priced at budget-level yet they yield big-buck performance. They have the construction and heft of much more expensive equipment. I don't know how they do it. I had a $199 10" Kicker sub a few years ago and it was on par with the AS10DF. I can't believe your equipment doesn't have a bigger presence on the internet.

Really good crips sound. Packs a punch for sure. Deep bass The shop I had install the box was surprised at the sound for its size Definitely worth the money. I’d recommend 100%

It has good bass for small cars.

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.
