    Great results from a slim sub
  

*by D***E on Reviewed in the United States on 23 May 2014*

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 little sub woofer
  

*by L***. on Reviewed in the United States on 28 September 2024*

I put this in my Armada to replace my old one. It's not crazy or anything. It's not going to blow out your windows or win and contests. But it does rattle the truck and you can hear it coming up the street. The build is pretty nice and compact. I'd buy it again
