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 300 A.

This compact powered subwoofer uses a beefy 500-watt amplifier and a 12" 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 10" 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.

  • powered 12" subwoofer enclosure
  • Class D amplifier (500 watts RMS)

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.

Awesome sound quality

Written By Anyone, Michigan on Tuesday, November 04, 2014

Crutchfield Customer Review (What's this?)

This Blue Magic is easy to install. I like that the amp has already been matched and is hidden inside the box making it a clean install. The additional features of having a volume control, and can be mounted anywhere. In the old days we had to pull over and crank up the dial- now it's at your fingertips. This easily fits behind the seat of an S-10 pickup with bucket seats/ or split bench. I complimented this with a new Kenwood excelon KDC-X598.

Pros: Easy hook-up, clean design with amp already installed- no guess work on compatibility.

Great buy

Crutchfield Customer Review (What's this?)

I was a bit hesitant on this setup, but I highly recommend it for those who want a hard hitting sub but like to save space. This beats the alpine type r 12 I had which also was pushing 500 watts. I love that it comes with the gain knob. I can adjust the bass for each song as I please from the drivers seat. Works wonders since I listen many genres. Going to purchase a second for my wife's car very soon.

Pros: -No need to find matching amplifier -Doesn't require remote wire ( turns on using signal from RCA) -GAIN remote control included - amp built in box

Cons: None so far

my first subwoofer

Crutchfield Customer Review (What's this?)

Easy install, especially with the wiring kit bought here. Just needed a big terminal ring for the ground cable because I used the seat belt bolt. Definitely use the remote volume control! Different styles of music will like this sub in different ways. I have a good jvc head unit so I can switch the eq on the fly. This boombox will give a decent shake to your car and get very loud.

Pros: Lots of fun

Cons: I had to buy an alpine amp to boost the mids and highs from my four polk door speakers. You might want to think about getting the wiring kit for two amps when you get this sub. I know I am glad I did!

Wiring not included with the sub. Kits make it easier and less expensive to install your new powered subwoofer.
Dynamat helps reduce ambient road noise and your vehicle's "rattles," making it easier for you to hear your music better. Easy to install.
It's critical to have good wire, and none is included with the sub.
Get more info about having your new sub put in by a qualified professional in your area.
If you are using the pre amp inputs on this powered sub, better quality cables will improve the sound.

This powered sub can enhance bass in any factory or aftermarket stereo system. There is an installation kit available for this application. I highly recommend it. [ MIKE  Jul 19, 2014 ]
I forwarded your question to an Advisor and they responded with the following: Pretty much any stereo with a subwoofer preamp output will be compatible with this powered subwoofer. Also so we can recommend correctly we need to know if you have the factory Bose audio system in the Altima? You will need the EFX 8-gauge Amplifier Wiring Kit to have this subwoofer installed. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  Jul 17, 2014 ]  Staff
