Review: Really good sound enhancement for your vehicle. - Great price for a great sound. It was a perfect fit under my Chevy truck seat. You could install this in a lot of vehicles with limited space. I have this connected to a Kenwood stereo that allows adjusting frequencies to the other speakers which allows the sub to do the lows and frees up the other speakers to handle the rest. Great system.
Review: Just fine for a modest system - I got this to improve the sound of the stereo and speakers in my '78 VW Beetle convertible. I chose it because it offered an amplified subwoofer in a compact package, which would make for a simpler installation. The unit has a cast metal case, looks nice, and is very heavy. It was too large to mount under the Bug's front or rear seats, so I mounted it vertically on the inside of the rear firewall, behind the back of the rear seat. I have a very inexpensive head unit, made by Dual (My car is a convertible, so if someone is going to steal the stereo they are not going to get much!), and two good quality 6 1/2" speakers in the doors. The speakers produce nice sound quality, but they don't offer much in the way of bass. The Blaupunkt subwoofer now gives me nice bass while taking a lot of load off the speakers. My modest system sounds much better. It is not going to win any stereo output contests, but it is just fine for cruising around with the top down.

## Questions & Answers

**Q: Has anyone used the hi level inputs on this, negating the need for an in line converter.**
A: Yes, fed off of speaker wires directly to the unit.

**Q: Are you sure this is a 10" speaker?  I see it listed on other sites saying it's a 8".  Same model number.**
A: No, it is an 8". The literature was misleading. They also make an older 8" that puts out less power. 100rms ? I have it in another vehicle. It sounds good. It won't shake the mirror. The older one has been in the other car for over 9 years, no problems. Adds bottom not a shaker. I like music tight not muddy. They both have done the job. Sorry about any confusion. I was going by the description.

**Q: What is the RMS power of this subwoofer?**
A: 120 RMS 200 MAX. Good to add some bottom. Not going to shake windows. Pretty clean.  Works if space is a issue. Had to put in hatch on my GTI. Wouldn't fit under the seat. I have the older version in my Mazda, it doesn't have as many watts but sounds good. I've had the old one in for five years, no problems. Not a boomer just a low end filler.

**Q: What’s the frequency response?**
A: 50-150Hz is the crossover frequency dial range, not the frequency response, which is not specified in the ad.

### ⭐⭐⭐⭐ It's not plug and play: take 10 mins to fine tune it
*by D***T on April 28, 2021*

I have to admit, when I got this thing and started removing it from the box, I was terrified that it was too big to fit my application, even after I had measured and re-measured. No worries! After some very minor modifications to the mount area, it fit like it was meant to. I admit that I used a pair of aircraft shears to trim the carpet and even remove a piece of plastic A/C duct. My vehicle, the 2007 Nissan Xterra, did not come with a factory sub, but they were all built with the same recess under the front passenger seat. **Basic Pro Tip: when you DYI a component such as a powered sub, take the time to ensure that all the settings match between the receiver and the sub or amp. It makes a MASSIVE difference if the settings between the components don't match. Take 10 mins and read about where to set the dials on the side of your amp or powered sub..there's a reason they still put tiny manual dials on the side. Also, most new head units give access to some sub settings, remotely through the receiver Sound: Still breaking mine in, but so far the Blaupunkt GTHS131 10" sub 350 watts, adds a nice thick bottom to my music. **Will revise review after tuning and testing for a few weeks. Update: Just as I suspected, all it takes is making sure that you follow same basic proceedures that you would to tune an amplifier. My Blaupunkt 350 powered sub sounds great! As described by other users, it won't rattle the glass of an adjacent vehicle, but it is exactly what I was looking for to add bass to my sound system.
