great sub for the money

I bought this for my son's truck and he is loving it. I went ahead and bought the version of this that has two woofers instead of just one, the BLB212LED. I can't wait to get mine!

He's super happy with this and doesn't have really any room to work with like I do in my hatch but dang, this thing rocks on a cheapo amplifier. We might upgrade eventually but for now, solid bank for the buck I tell ya'.

Amazing! One tiny issue but they are solving.

I am very excited about this product, but a little bit frustrated. Read on for details.

First, the sound on this sub is really amazing for the price. I cannot complain one iota about the sub, the grill or box. Last sub I had was in an Atrend box and the carpet was not even as good as this and the box alone was more than this entire set up.

I am powering the box with a Crunch amp and I wasn't expecting to get as much bass I have from it. The port probably really helps and I enjoy the lower bass much more now than when I had a similar setup of a lower power sub and box.

OK, now for the ugly. I did not get my illumination cable and I guess I am one of the first people to buy it because I emailed them and they immediately looked into it and apologized to me. They have since added a message for others which is nice, but I really really wanted to see the illumination. I will write a new review as soon as I get the cable in as they said they would ship it out within a week or so.

Here's the thing! Even without the illumination, I am really happy and I am ironically even more happy that Sonic actually took the time to look into my problem and is solving it. Kudos all the way around.

Not worth it

I bought this mainly cause of the led lights. The light doesn't work and the box is poorly made. Didn't get a remote with it. And it came in a retaped cardboard box.
