BLAUPUNKT GTHS-81PRO 8" Amplified Subwoofer 320-Watts Active Flat Compact Design

Good bass for such a small box. We put this in a 09 Honda Fit. It didn't fit as well as we would have like under the passenger seat, so we put in under the rear seat in the middle. The subwoofer connections were the easy part, the hard part was getting the audio and power to the box.We used high level signals from the rear speakers and because the stock stereo had no "remote" wire to turn on the sub, it was great to find that the sub has audio signal sensing which turn it on/off as soon and the high level signal is sensed from the speakers.Unless you already have it, I would suggest you buy an install kit with at least 8 AWG "primary" wire (as suggested in the manual) and a minimum 40 Amp fuse mounted at the power source. Kits online are far cheaper than what I found around the Portland, OR area stereo shops.Overall, you won't be cracking windows with the bass from this unit, but it sure evens out the audio in the car as the stock 6.5" Honda Fit speakers provide little if any audible bass response.

Added this to my 78 Vette and what a difference it made....easier to install and the bass is incredible and worth the proce

I needed something to fill in the low frequencies in my RV. I was expecting super lows as im realistic. But for its compact size it does sound very nice. More importantly it fit nicely under passenger seat. It seems well designed and heavy construction.

Had a good clean punchy bass. I'm impressed with the sound quality. It's in a single cab ranger behind the seat facing forward right behind the arm rest and fills the cab with a nice sound. I'm using a JBL deck and 4 JBL speakers ran off the deck only. Adding this blaupunkt powered sub fills in the rest perfect. You won't win any competitions but you will have good sound quality and it does thump pretty decent but I haven't been working it to hard till it breaks in a lil more.

My small sporty car came with a crappy audio system. Did NOT want to tear out the insides, panels and plastic bits to update the whole system. This powered sub fits like a glove under the seat. Of course, for ANY addition, you must install power from the battery, signal feed from left/right speakers etc.. That took some time. Previous experience doing this is a plus. Added dome tweeters in the rear while I was at it. Adjusted the settings and voila!! Quite happy for this $200.00 total investment. Hope it will last a few years at least.

Sounded better than I expected. I was looking to add extra base in my convertible. This did the trick.

Must be mounted solid, then works awesome

Defective. Unit I received had been previously opened so who knows. I installed it anyway and got a power light for about 20 seconds and then a red protect light for a second. The 15yo fuse didn’t blow and I had power on the 12v and Remote starting wires. Returned to vendor as nonfunctional
