Turn it on

So your music sounds a little thin and you want some low-end oomph, but you don't want to install a bunch of gear in your vehicle to make it happen. Enter Blaupunkt's Blue Magic XLb 250 A.

This compact powered subwoofer uses a beefy 250-watt amplifier and a 10" sub to give you the low-frequency punch you need to round out your music. You can use the variable crossover control and phase switch to tune the bass for your vehicle, and you can crank the bass boost dial if you want even more low-end throttle.

Once you've adjusted the settings, you can turn up the bass output right from the driver's seat using the wired remote control that Blaupunkt includes.

Easier installation

There's no need for the conventional 12-volt remote turn-on wire connected to your car stereo. Instead, this Blue Magic sub fires up automatically by sensing the incoming signal coming from your RCA cables or your speaker-level inputs. It's a simple way to get your bass going.

Blaupunkt XLb 250 A powered sub panel

Detach the power and ground connector for quickly removing and re-installing the Blaupunkt sub.

Take it out (when space is needed)

At only 9" deep, this compact bass blaster can fit in some tight spots. But let's say you need some extra room for your groceries, camping gear, or golf clubs. Blaupunkt makes it easy. Simply unplug the power and ground connector, detach your RCA cables or speaker wires, and remove the sub for more cargo space. When the cargo is unloaded, you can quickly reattach your subwoofer to get your thump back.

This sub's tough enclosure can withstand the bumps and bruises of life in a trunk or cargo area, and the speaker's protected by a stylish, heavy-duty grille.

Who needs a powered subwoofer?

To produce bass, you need a sub, an enclosure, and an amplifier, and it can be little tricky to match them all up. A powered sub eliminates all the hassle, as the manufacturer designs the enclosure to house the sub and amp together. This all-in-one solution is especially useful in smaller vehicles, where there's no room to mount a separate amp, or in any vehicle where you need every bit of cargo space. Powered subs range from small, flat boxes that fit under your seat to larger boxes that go in your trunk.

Great bass and kick

Written By Dave, Hawaii on Sunday, October 19, 2014

Crutchfield Customer Review (What's this?)

Great bass and kick, allthough I don't listen to music at "11" the xlb delivers a nice heavy kick and deep bass. Another nice feature is the included remote volume adjuster that lets you adjust foe each song.

Cons: none

Blaupunkt-Awesome German Engineering BMW E46

Written By RayQ, Atlanta, GA on Wednesday, June 04, 2014

Installed this on a BMW e46 with factory stock radio and speakers non-HK & non-GPS Navi. I blew both woofers on the stock radio setup and specifically the 2 ohm woofers mounted on the rear deck. I purchased this as a replacement woofer to pick up the 20 -250 hertz low range, along with a set of 5/12 speakers for low-mid frequency fill in the 60-2k hz range to replace the rear deck speakers. Wow! Truly an OUTSTANDING woofer for the price and the sound is perfect fill even when mounted in the trunk facing away from the back seat. I could not be any happier with the sound pressure that it produces inside the BMW 2004 325i and I just can't imagine how much SPL would be heard if installed inside the cab itself. The line level inputs are perfect for this setup and requires NO splicing if using split clips to tap into existing speaker wires; the brown wires are ground and the white wire is the remote turn on 12v on a BMW. This was icing on the German Chocolate cake! :-) Play with the settings on gain, freq cut off, and bass boost; however, I found that the box is nicely tuned already. I ended setting everything at the low end for all setting on the amplified woofer variables. I can also make some adjustments on the radio to control bass, treble, fade to further control the woofer output. Danke! I would love to post some pictures that I took of the set-up if Crutchfield would let me and let others see how easy this was to install.

Pros: Settings to control gain, cut off frequency, and bass boost. Excellent bass from 250 hertz down to 20 hertz Small size and excellent construction

Cons: No wires included, it would be nice to include 6 feet of 8 gauge of red and black wires. A blue remote turn-on signal wire and a couple more fuses.

Crutchfield response on Monday, June 09, 2014 We would love to see pictures of your install. You can post them to us on most social networks, in our forums or submit your vehicle to our Custom Car Showroom .
