    • Great sub, wide soundstage, solid build quality

I was a little sus due to the single blurry photo but I decided to pick it up due to the good price and that it's a compact, ported sub. Haven't installed in car yet but I've been running it off a 12V 5A power supply and comparing it to my home theater subs. It definitely exceeded my expectations for it's size! And the build quality is great. It's solid and all-metal. (Good thing too cause my Amazon driver literally threw it on the porch with no protection in the HEAVY RAIN, took a blurry photo, and ran. But it's fully intact.) I'm not some A-hole bass head and was looking for something that can do balanced bass as well as hit those low notes <35Hz that even some 12-inch subs can't hit. (Size ain't everything folks.) It definitely delivered, goes down to about 30 before dropping off, outperforming my 10 inch sub in all but volume, and feels like a wider soundstage. I do have one sub that outperforms it but that makes sense given it's part of a very expensive Atmos system that uses mics to do active room-correction. The fact that it crushes all my other subs in soundstage, even the bigger ones, is still impressive. Sure, at only 100 watts RMS it doesn't get SUPER LOUD compared to some beefy subs, but it's loud enough that 50% can SHAKE YOYR HOUSE BABY. And I value my eardrums, so that's good enough for me. ... show more

    • Huge bass in a small package!
I installed this subwoofer in my Scion iQ because there is a lack of any real usable room or mounting space for a sub. After looking at other compact subs I found this one to have the correct dimensions to fit under my seat (3 1/8” tall) and the price was right, but was a little leery about such an inexpensive self-amplified sub. Turns out, this thing is awesome! My other car has a 10” Polk with its own amp, so I’m used to big, usable, and sometimes powerful bass. I’ve installed and enjoyed many sound systems, so I’ve developed an ear for good sound. The Blaupunkt fills my car with lots of bass, and sounds great after fiddling with tuning it. There is some distortion close to the upper limit, but the rest of the sound system is too loud for you to even be in that range in daily use. The sound is full and not cheap or tinny, and puts a smile on my face. From standing 10 feet away from the car I can hear the sub noticeably but not loudly, and this is with the radio at about medium volume. This is a good option for cars with smaller interior volume I guess, but maybe a pair of these would work for a larger vehicle. Overall, I’m very impressed with this little box and am happy everything turned out so well. I definitely recommend. ... show more

    • BIG TIME BANG FOR BUCK!
I was a little skeptical but that soon turned into a grin after the install. Put this little sound gem in rear of F250 crew cab with 2 pair of Focal ISU 165 component speakers And Kenwood DMX47S head unit. Install for this amplified sub took about 1.5 hours to install with a wires and cabling tuck neatly under the carpet. Wow what a difference in the full body sound that I did not fully realize I was missing. It will not kidney punch you, but the realism and sound definition is amazing, and what this little puncher will bring to your system is a very good value when on a budget. I will purchase a second one soon for a little more punch. ... show more

Amazing bass for little box. But looks like this is a no good product. I saw bad opinions and looks like the bad is for the same issue. The product works good for the first week but then suddenly stop to work. I feel sad because i trusted on this brand, but looks like even if is good materials quality and good numbers/ specification, the real quality or durability of the product is not the best. ... show more

    • A really good subwoofer for our car
Installed into 1993 ford mustang Gt 5.0 hatchback behind passenger rear seat facing hatch connected to a Boss head unit and cerwin Vega HED 4x5 rear and 5” diameter in doors. This subwoofer added everything that the original system was missing. Has clarity and easy to adjust. Would not fit under front seats, passenger side would had allowed rear passengers to place feet on amp so not good and had to mount in rear of car. ... show more

    • Tiny Big Bass
I couldn't wait to install this in my 2007 Ram quad cab. I used Boss Amp install kit for wiring (a must have). Along with the kit install under the driver seat was quick and painless. This complement my after market door speakers perfectly. You won't hear me a block away, but inside the cab it sounds amazing. The bass is what was missing from my 4 way 6 x 9's. My wife even really enjoyed the sound. I didn't have a huge budget for sound but I'm glad I found this Blaupunkt and even happier that it fits under the seat and saved room for the kids. ... show more
