If you crave high-performance bass but don't have a lot of space, Infinity has a great solution — the BassLink II car subwoofer. The engineers at Infinity used state-of-the-art technology to create this compact, powerful, and expandable amplified sub. Though it takes up just one cubic foot of trunk space, it'll produce resounding bass in any vehicle.

The BassLink II brings together a 10" square subwoofer and a specially designed 250-watt amplifier, and then adds a 10" square passive radiator (non-powered speaker) to increase efficiency. This inventive combination provides loud, clear bass in a fraction of the space taken up by conventional sub boxes.

An array of controls lets you tweak your bass for the kind of thump you want. The low-pass filter adjusts the range of frequencies amplified by the BassLink II, while a phase control ensures that the sub works with the speakers in your car, not against them. Raise or lower the bass impact with the bass boost feature, and control the level with the wired remote.

Mounting brackets allow you to install the rigid polymer box vertically or horizontally, so you'll be able to fit this compact enclosure almost anywhere. And you can connect this powered sub to any car system, even a factory radio.

The BassLink II is also expandable, with a port that allows easy connection of Infinity's 4sc multichannel amp module (sold separately). The module provides 50 watts of power to four channels — plenty of clean power to drive the other speakers in your car.

Product Highlights:

  • compact powered subwoofer
  • 10" square woofer and passive radiator
  • Class D 250-watt amplifier
  • wired volume control with 16-1/4' cable

  • warranty: 1 year
  • Our 60-day money-back guarantee

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.

Crutchfield Customer Review (What's this?)

Spent 3 days wiring my car and installing this unit. It worked great for about 1 week and something died in there, so it would make constant loud buzzing sound even when not connected to any audio signal. After that, I have read lots of compaints in regards of this model related to its poor reliability. Had to spend another day removing all the wiring in order to send this unit back. I'm glad I bought it from Crutchfield, not some other unknown retailer.

Awesome :)

Crutchfield Customer Review (What's this?)

This thing rocks. I put this in a Chevy Silverado Extended Cab (4 doors, rear doors open opposite of front doors). It JUST fits under the rear seat. I haven't fine tuned the system yet, but I am VERY pleased with this.

I initially purchased the Blaupunkt Thb 210A, but the Infinity Basslink is much better. If you can fit this and don't want to mess with building a custom subwoofer box, this is for you. And with the free multi-channel amp module you cannot go wrong.

I also have to commend Crutchfield on their awesome service. Free shipping. And free return shipping if you don't like it. What more could you ask for? You think other places are going to give you service like that? I don't think so.

Crutchfield Customer Review (What's this?)

I wont hurt the rating, but i recommand the basslink to be used in a opened type cabin (ex: Vans, SUVs, trucks). I have this in my trunk right now, the bass is very clear, accurate, and audible "IF" you do mostly city or low speed driving, but once you hit the highway, the bass pretty much dissipates. The basslink does reproduce the low notes very well. The unit hardly distort at all unless you crack the gain to the max position of course. I wanted a unit that can be audible at any driving speed but don't want a subwoofer thats heard blocks down the road.

Nice sub

Crutchfield Customer Review (What's this?)

Bought this sub and the 4sc amp. It sounds very good. I've had systems in the past that would wake up the block, but that was when I had younger ears. For what I wanted this did the job with a couple of exceptions. For certain bass notes, the sub system clipped even though I wasn't near the top of my volume nor did I have the gains turned all the way up. I developed a short in the 4sc module so I had to return it for a replacement. Did that and had my sound back, then my sub went south so I had to get it replaced. I commend Crutchfield for working with me on this. I then decided to go with just the sub and a separate Kicker 4 channel amp. Sub on it's own sounds good, and the Kicker amp is much more powerful than the 4sc module. You're also hurt if any part of the basslink II and 4sc system go out because once something goes down with that set-up, everything goes.

Great in the right setup

Crutchfield Customer Review (What's this?)

When I bought this unit, I knew little to nothing about sound systems, and this unit was a blessing. While this unit doesn't quite have the power to pound through back seats and wake up your neighbors when you get home, it sounds great in any car where it's in the cab with the driver. It's easy to use and is perfect to bring an otherwise factory system to life, the amp expansion provides plenty of power for even large speakers and the built in crossover in the unit lets even poor factory speakers belt out the mid and high notes by eliminating the low frequencies, and the sub itself will rattle your car, not the one nest to you, but it sounds great in your ride and that's the important part. Now for the negatives, if you already have an after-market head unit
which includes a subwoofer control the built in crossover is no benefit, nor are the speaker level inputs. Bottom line, system builders stick to the standard box, amp, sub combinations but if what you want is a unit that will breathe life into a struggling factory system and nothing more, this is a GREAT unit, although if pushed to far it will develop an unbearable rattle and repair or replacement is MUCH more expensive since you cant just replace a part of the system, you have to replace the entire thing. Still a great product especially for SUV's and hatchbacks with systems that just can't cut it.

This thing rocks!!

Crutchfield Customer Review (What's this?)

I originally purchased an Alpine CDE 9881 head unit and Infinity Reference 5 1/4" and 4"x6" speakers from Crutchfield to replace factory equipment in my 97 Jeep Wrangler (not my first purchase from Crutchfield) . Made a difference, but I realized that I needed more low end and more power. So, I called up the Crutchfield folks a second time in two weeks. I asked about the BassLink II (the fact that they were including the 4sc module was a major factor in looking at this particular sub, but I would say now that I would definitely pay for it as well) and asked if I was headed in the right direction. Norm at Crutchfield looked in his info database and told me exactly what I would have to do for install, after telling me that he thought the BassLink with 4sc module would be a good addition. He did not lead me astray.

I had not installed a sub or amp before, & it was a pain in the rear, but I definitely bought the right equipment. I read in a couple of the reviews for this product that it was not worth the money. THIS IS SO NOT TRUE. I am ecstatic with the results. I have some great low-end THUMP that I can both hear and feel. I listen to everything and can get some of that back-massaging punch from Soundgarden & Godsmack to Beck to Nelly & Black-Eyed Peas. The 4sc module makes my Infinity speakers absolutely shine (both highs and mids are crisp and absolutely clear, all the way up to the max volume). I love the wired gain control for the sub, especially since I listen to such a wide spectrum of music & I can tailor the sub gain for each song easily.

Both the sub and the amp module are great! Crutchfield Rules!

I returned it twice to get replaced within a years time. First it had a weird buzzing sound like the speaker was blown, but it was fresh out of the box. The second time it just stopped working. It sounds ok when it does work, but next time I'll just buy an amp and a box. It sounded better whaen I had that set up, but I was just looking to save space that's why I got the basslink.

I like hard rock and was just looking for solid bass and hard driving guitar sounds. Along with 4 polk speakers and a JVC deck, I got exactly what i was looking for. Put the amp in the center rear floor of a '95 F 150 supercab. Easy job. Doug at Crutch field was very helpful at matching components and system was shipped in a couple days.

Crutchfield Customer Review (What's this?)

I installed this in an 07 Accord and it is great. It is plenty loud (installed in the truck) and the bass is easily felt and heard throughout the cab. This is with the gain and volume levels set fairly low. I was looking for a low-end presence that was lacking in the factory set up and this is exactly what I got. I give 4 stars and not 5 simply because frequent adjustments on the remote are needed when switching CD's or types of music.

The Basslink II can shake your your whole car and give you a back massage of bass if you want it to.

Crutchfield Customer Review (What's this?)

I was very disappointed with the Infinity Basslink 2. I ordered it with the 4SC expansion module, installed it in my VW Golf, and the next day sent it back. Bass is seriously lacking, especially if the music isn't already heavy on bass. The 4sc really didn't do anything the head unit(Alpine 9883) couldn't handle. For the money, I was expecting something that would at least meet my expectations, but this thing was just sub-par. I exchanged it for an Alpine 5 channel (MRV-450) from the outlet and a Rockford Fosgate 1X10" Punch 2 bass enclosure and the difference is like night and day! Thank you Crutchfield for the exchange!!!

Loud in a F150

Written By charlie, Paw Paw, MI on Saturday, May 12, 2007

Crutchfield Customer Review (What's this?)

I put this in '05 F-150 super cab with the factory radio. I had to remove the small rear seat because the back of the seat does not fold down. Running the wires was the trickiest part. I made all connection in the door,(did not have to remove the radio)so it would be easier to switch back if need be. Not sure if that's right but it sounds great and works fine. I do plan on upgrading the radio and using the RCA connectors. I did upgraded the factor speakers to the Infinity 6812cf which also sound good in the truck. My small problem is it gets pretty loud in there and I lose a seat.

Hmm, not so much....

Written By Pat, Howell, NJ on Wednesday, May 02, 2007

The idea of this thing is brilliant, but it surprises me that Infinity released such a product. The other reviewer that said you'll need a line out converter was completely right, or else you won't be able to turn the music up loud because the sub cuts in and out at high volumes. The line out converter seems to cure this. It definitely isn't loud enough to be used in a trunk. I imagine it would sound better in a hatchback or SUV where there's no seat in between the sub and the listeners.

On the positive side, installation was quite simple. Just a matter of wiring it up to the factory speaker wires and running the power line. If you've ever installed an amp before, this should be easy. The sub is constructed well. I never mounted mine and it's been tossed around the trunk a bit with no changes in performance, or visual damage for that matter!!

My honest opinion - If you're looking for hard, deep bass - go with a traditional amp/sub setup. If you've got a hatch or an SUV and just looking to add a little punch to your factory setup, then this Infinity might be ok for you. Just make sure you get the line out converter!!!! For my Accord, I'll be replacing it very soon with something a bit more powerful. :-)

Crutchfield Customer Review (What's this?)

A few years ago I upgraded my speakers to a set of Cerwin Vega components... very nice upgrade from the stock Infinity setup. However, 6.5" speakers will just not play low notes with any grace... you get the 'hit' on the bass note, but no note.

So I purchased a Basslink II with the 4sc amp, as well as a HD tuner. Installed the tuner first, and even with it's internal amp there was an improvement on the basic sound. After running all of the wiring, I was finally able to fire up the Basslind and IT'S amplifier.


Turn the bass down at the amp, and just listen to the Cerwin Vegas. Niiiiice... clean sound, real presence. I played Dance, I played Classical, I played Flamenco guitar. I broke out the old Electronica... then the hair bands... then the Mannheim Steamroller... I was looking for all of my old music, so I could listen to it the way it was meant to be heard.

Now, turn up the Bass. Heheh... had to start all over again. My commute is too short to hear too many songs; I've had to go out driving on my days off... this thing may be bad for the environment!

All around great deal. You won't go deaf, but it IS painfully loud at full volume, full gain. The Basslink has adjustments for Front Speaker gain, Rear Speaker gain, SUBWOOFER gain... it has a crossover point adjustment, and a bass-boost adjustment... and a remote Bass Level adjustment so you can crank the bass when that one song comes on... ;) Setup instructions are included, so you can find the loudest settings possible without distortion; I turned it down about 20% from there. (Nothing says you have to listen to it at it's loudest!)

Crutchfield Customer Review (What's this?)

I installed this unit with the 4sc expansion unit. I also installed infinity 6010 series component speakers in front and polk 6X9s in the rear deck. After running 120' of wire and installing the line converter, this thing has a great sound. It's a very good and inexpensive way to add sound to your system. I installed everything for under $700. I still have to install the remote and play with the phantom center. But, so far this unit is well worth the investment.
It distributes great sound at low and high levels. The best part is that my wife likes it as well.

2005 Jeep Wrangler. Kenwood Exelon KDC-X590 head unit, Infinity Reference 6412cfp 4x6 in dash locations, Infinity Reference 5012i 5 1/4 in the roll bar. I hooked up the head unit and speakers and had to wait to install the Bass Link for a few days. The sound wasn't that good. Hollow. It's hard to get depth in a Jeep. Then I installed the Bass Link II with 4sc, and it brought the whole system to life. If fit nicely behind the rear seat, but you lose half of that space. The bass is clear and solid. It won't rattle your teeth out, but has enough punch. The extra power of the 4sc amp really helped the Infinity speakers. Set up wasn't too difficult. I need to add filters to the other speakers. As an off the shelf package, it is perfect. The only wish I have is for a separate set of pre-amp inputs dedicated to subwoofer output from the head unit. My Kenwood has 3 sets, and with the current setup, I can't use the filters Kenwood has built in. Overall, well worth the money and simple to install and use.

F150 E-cab with factory tuner/cd changer

Written By pilot, Howell, MI on Tuesday, November 07, 2006

Crutchfield Customer Review (What's this?)

My truck has better sound than my living room does now. The Infinity bass-link II/4sc combo , Polk tri-axials in the doors, acoustic damping on 4 doors & rear cab, baffels on door speakers, 1.5F digital capacitor, Sirius PnP with FM cable antenna modulator and a factory male/female cable connector with wiring harness(self made). Bass link occupies the space where the left rear jump seat was, so that results in good corner loading to maximize the low-end cabin gain. I even milled a portion of the center out of one of the supports so that it would straddle a contour in the sheet metal, allowing the rear most position possible.
Really incredible sound, and used the original reciever cd/changer, that saved money.
I listen to jazz, classical as well as rock. Having the remote bass boost control makes it convenient to make adjustments while driving, when the music styles change.
The two sets of instructions on setting up the amplifier controls led to some confusion, but once you figure which one applies to your situation you're ok.
I took step by step photos of the whole process, like a slide show/how-to. It's a great feeling to turn on power the first time, not see any smoke or have to trouble shoot wiring f/ups. Even beter to twist that knob up to the top, and not have any distortion. Loud, but not uncomfortable. Set it at 1/4 vol and listen to crisp and clear reproduction of jazz accoustic bass. I'm very pleased with the result. The Crutchfield Bonus Free 4sc makes it a really great deal too!

I have a Jeep Wrangler, and the biggest speakers are 5 1/4". I needed something to fill in the bottom end of my music. The Basslink II does just that and installs easily behind the rear seat. I added the 4sc expansion module to drive the Infinity Reference speakers. The whole system sound great, excellent bass even at a conversational volume or with the top down. Even my wife is impressed. I will probably replace the supplied capacitors with an actual crossover to further reduce the amount of bass going to my speakers.

This thing sounded really good when it worked. It was a pain to get to work though. I have a factory receiver, and I don't recommend this if you have that. You'll have to end up using a line out converter, which I found out after much hassle. This thing worked for about 3 months, and then it blew. I don't listen to my music that loud, none of my speakers are blown, and they have a lower rating than the sub did.

I installed this unit with the 4sc amp in my 97 Saab Conv. Installation was easy considering all of the wires run to the Basslink. I have spent time listening so far only with the top down, which would be the most demanding of the low end. I am thrilled with the amount of bass as well as it's quality. I installed 4 Polk 6.5 and wired to the 4sc for an amazing system. I listen primarily to rock/jazz style and this combination is wonderful for my listening needs.

I purchased this subwoofer with the 4sc amp upgrade, and I must say that for what it is, it is awesome. Lets me start off by saying the 4sc is an amazing amplifier. This amp rivals the clarity of my previous alpine 4 channel amp. It is powerful, and doesn't take up trunk space. That's great. The subwoofer in this setup is very good for what it is. It has great clarity and accuracy. It is not a sub for someone who wants to rattle the block, but is produces good clear bass. I have a 2003 saab 9-3, and I am looking toward having kids, and I wanted good clear sound without filling up my trunk. This sub allowed me to do just that.

I own a 2005 Honda Accord 4 door sedan and I was looking for more bass from my system with out taking up my whole trunk. I did a lot of research on subs to put in my car and I came across the basslink. I got the basslink installed about 3 weeks ago and I couldn't be happier. At first I was a little dissapointed in the bass response untill I flipped the phase switch and then the bass came to life. I feel the bass in my back of my seat with a nice punch. It hits just as hard but cleaner than my friends infinity 12 inch reference sub he has that sub in a 2004 accord 4 door. I also purchased the 4 channel amp that goes inside the sub and it sounds great even on factory speakers. I suggest this sub to anyone who is looking for a nice ammount of bass with out all of the hassles of a big system.

Crutchfield Customer Review (What's this?)

If you are looking for a nice way to add some bottom end your search is over but if you are looking for some solid bass that you can feel in the front seat stick with the traditional amp and subwoofer. I installed this powered sub with the line converter and was pretty disappointed as the bass has just under the power needed to get the bass massage we know and love. You can at times feel it from the front seat but it leaves you hanging and wishing for more. Background info: I installed this in my 2006 Honda Civic Si up against the rear seat with the sub firing towards the back of the car. This was the recommended configuration. It sounds nice but, as stated, comes up short of delivering that solid hit. Overall musical clarity and reproduction is fantastic and is the only reason why this powered sub received 3 stars from me.

One of the best Powered Subs

Written By Franco, Queens, NY on Tuesday, February 28, 2006

I rated it a 5 for now. I have a few issues I am working out with my vehicle but I believe its all on my end... so I didn't want to hurt the rating. Let me say first off, I run a 1000W RMS sub in my truck, and I understand what real bump is. That being said, this 10" 250W powered sub is one of the best sounding powered subs I ever heard. Give it the power it wants, and it Bumps hard in a car. I can't speak for it in a truck. It hits lows pretty well.. I give it a 80-90 for hitting lows. I wish I could "feel" the bass more with it, but it definantly gives you a very Clean sound. If it starts to lose power for some reason (issue I am having now), amp auto compenstates and lowers output volume so you only get a clean sound. I recommend having the unit lying down, instead of standing up.

I put the basslink II in my Porsche 944 and it bumps. Installation was just a matter of running wires the basslink did not give me any problems at all. Obviously someone purchases this item because they want good bass but don't have alot of room. This thing takes care of both. I still have a majority of my trunk left and the bass is outstanding. In a car with small amout of interior volume like mine this baby sounds just as good as your conventional system.

Infinity BassLink II

Written By Timothy, Toledo, OH on Saturday, July 16, 2005

Crutchfield Customer Review (What's this?)

Excellent so far. I purchased this to replace a Kenwood powered sub that I had beat on for several years. I am amongst the first to obtain this, so only time will tell if this will last as long as my previous sub. I had settled on the original Basslink, but I decided to wait for this due to the newer design, increased power, and my curiousity in the 4sc module. I will say this is heavily geared towards those that want to add to an existing factory system, at least as far as adding the 4sc amp is concerned. I wish this had a seperate subwoofer input for a receiver that has seperate outputs, it would give more flexibility in making receiver level adjustments. As such, I'll probably pass on the 4sc but I understand Infinity's reason. As just a powered sub, I think most will find the available adjustments more than adequate. I just set everything to the middle (except crossover) and made adjusts via my receiver. I even passed on using the wired remote, though I am happy to report the Basslink II works well with any receiver level adjustments you throw at it. I put mine in the corner of the trunk and I really appreciate the compact size. Despite the size, this is doing as excellent job in filling in the lower frequencies. It goes without saying this isn't for bassheads, but I would think most would avoid this anyway. Still, the output is quite substantial and if you like your music balanced, but sometimes loud, this suits nicely.

Just Installed

Written By getagrip15, Asheboro, NC on Thursday, July 14, 2005

Just got this in the other day for my birthday and had it installed last night. First off, it was put in my 2005 Honda Accord EX 4-door. I bought an 8 gauge amp kit online and also bought a line converter to run an RCA cable from the factory stereo to the Basslink. I had a little problem with the lazy employees at a local dealer, who installed it without the line converter because they thought it would be easier. Needless to say, I made them redo it. Anyway, troubles aside, I'm really liking it so far. It has a nice full sound(even in the trunk of my car) and can really hit pretty low. It is really nice that it takes up almost no space in my trunk too. It is a very nice upgrade to a factory system, and a nice choice for a leased car, like mine. In my previous car I had 2 JL 12s and a huge MA Audio amp that just pounded, so I'm not one of these people that makes claims that this thing can compare. If you want to be heard down the street this is not the sub for you. If you've grown out of that, but still want a nice full deep sound, this could be it. Make sure you get the line converter. I heard it before and after and it made a difference.

Product Research


Product Overview: The Infinity BassLink II is a self-contained powered subwoofer system which includes a 10" square woofer and a 10" square passive radiator. It is powered by a 250-watt, Class D amplifier.

Square Drivers: The BassLink II is equipped with a square subwoofer and a square passive radiator. This design maximizes cone area for maximum bass output from a modestly sized housing.

Mounting System: The unit can be mounted vertically or horizontally, thanks to its unique mounting system. The dimensions are as follows:

  • Vertical: Width=15", Height=15", Depth=10.243"
  • Horizontal: Width=15", Height=9.75", Depth=15.125"

4-Channel Inputs: The BassLink II is equipped with four line-level RCA inputs and four speaker-level inputs. Any combination of line-level and speaker-level inputs can be used to provide non-fading bass when connected to a head unit with four outputs. Note: For head units with only one pair of RCA outputs, or with a dedicated subwoofer line output, you should connect the RCA cable to the front inputs.)

Remote Bass Level Control: You can control the volume of the BassLink II from the driver's seat when you connect the Remote Bass Level Control module. The module can be mounted under the dash, or disassembled and mounted in the dash for a factory appearance. The module comes with a 16-1/4' control cable. Dimensions: Width=1.621" (2.285" including screw tabs), Height=0.893", Depth=2.623" (including knob).

Front Panel Controls: The BassLink II features a power LED (glows blue when the unit is operational) on the front panel, and the following three rotary controls:

  • Gain: The gain control should be used to adjust the volume of the BassLink II, relative to the other speakers in the vehicle.
  • Low Pass Filter: The BassLink II is equipped with a 12dB per octave, 50-120Hz variable low pass filter.
  • Bass Boost: To correct any perceived peak or dip in the bass response, you can adjust the 40Hz bass boost between -6dB to +3dB.

Right Side Connections/Controls: The unit's power and signal connection terminals are located behind a removable panel on the right side. The connections and controls are as follows:

  • Speaker-Level Inputs (4-channels): Two 4-pin Molex connectors for the supplied speaker-level input harnesses (Input Sensitivity: 1V to 16V)
  • Line Inputs (4-channels): Two pairs of female RCA jacks for the included patch cables (Input Sensitivity: 50mV to 4.0V)
  • Auto Turn-On Switch: Activates the automatic turn-on circuit when using speaker-level inputs. Unit powers on when signal is detected, and turns off a short time after no longer receiving signal.
  • Phase Switch: Reverses the output of the subwoofer with respect to its input. You should choose the position which results in the best bass.
  • Servo LED: The LED glows blue when the subwoofer is at maximum excursion and the amplifier is modifying the output to maintain maximum performance. (If the LED glows constantly, the gain should be reduced.)
  • Remote Bass Level Input: RJ-11 jack for connecting the remote bass level control
  • Power Connections: Gold-plated screw terminals for +12V, Ground, and Remote turn on leads, 8 gauge wiring kit recommended (not included)
  • Fuse: one 25-amp fuse

BassLink 4sc: The optional BassLink 4sc is a plug-and-play amplifier designed to allow you to easily upgrade your system. The BassLink 4sc slides into a slot on the BassLink II (covered by a 7-1/2" x 2-1/4" removable panel), and plugs into the two provided harness connectors, sharing the BassLink II's power and audio connection. Once connected, the BassLink 4sc delivers an additional 4 channels of power to drive the vehicle's front and rear speakers, plus ample bass from the BassLink II.
