Got enough juice? Get an amp for your new sub Kicker Solo-Baric L7 subwoofers have a look and a sound that is sure to set your system apart from the pack. The unique square shape demands that you take immediate notice of the 04S12L7 12" subwoofer, and an aluminum-treated cone with a thick Santoprene rubber surround handles the kind of power that guarantees you'll be livin' loud.

And this sub is loaded with extras that have made Kicker such a dominant name in bass. An enhanced cast-aluminum basket minimizes resonance from the motor assembly, while a rear cone brace controls flexing that can impair sound quality. Perimeter cooling helps it run hard and long without distortion, and the dual 4-ohm coil design offers extra wiring flexibility.

While the original Solo-Baric is recognized as the first small sealed box woofer, this L7 sub is more versatile — it works great in a sealed or vented box. So whether you prefer your bass tight and punchy, gutbusting, or just way down low, this subwoofer delivers.

Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible. Most car amplifiers are stable down to 2 ohms in standard mode, or 4 ohms in bridged operation.

Priced per speaker

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

Kicker Solo-Baric L7 04S12L7

Written By s10yellowed, jacksonville fl on Friday, December 30, 2005

I have two kicker 12 l5's in a regular cab s-10 in a 5 cubic foot ported box running off a 1500 watt memphis d. These speakers quake. I suprized my stereo shop when i pulled up cause they said it was impossible to put two 12's in a regular cab but we see who should own a stereo shop now. They couldnt believe it. You can literly hear me coming from a mile away. Best subs ever. So loud. Also running polk db 4x6 and polk db 6 1/2s in doors with polk db tweeters off a jbl 75x4 amp with panasonic deck. The new one with color graphics [dont feel like getting box for model #] if you want something that rattles stuff inside of your house these are it and remember you can put anything into anything. Car stereo shops are useless and a ripoff. s10yellowed out.

Kicker L7 12

Written By Steve, Ocean, NJ on Thursday, December 22, 2005

I just put this sub into my 2004 Mazda 6 5-door, powered by a 1000 watt memphis amp and I could not be more pleased. After having 2 Earthquake 12's in past truck, i find that the Kicker gives off and much cleaner, and more crisp punch with each knock of the beat. Definatly would purchase from Kicker again... 5 stars



Written By BEEFYKID, Colonia , New Jersey on Monday, November 28, 2005

Well i just put 1 of these in my 2001 VW JETTA,with a 1000tbd Rockford amp. Not to say these no knock but if you really want to shake your car get 2. One is good if you want something to play with, overall great bass but will look into another one.

These are it.

Written By Josh, Lake Ozark, MO on Sunday, October 02, 2005

I have two of these 12" L7's each hooked up to a concept 1200D and they kill. I have had alot of different set ups, everything from audiobahn flame Q's to alpine type R's and even the kicker L5 12's and these L7's are by far the best set of subs i have ever had. I know they are expensive but they are worth every penny. Be prepared to shell out about 300 for an amp to power one of these bad boys..and you better invest in a capacitor because you will need one of those too, and dont forget the dynamat because all of your stuff will be rattling.

Written By Gloria, Ohio on Sunday, September 25, 2005

I own two Kicker L7 12's and I also own two kicker L5's and In my opinion they are the same exact subs you might as well just buy the L5's they handle just as much power as the L7's and are just as loud with the same ammount of power.

Crazy as Heck

Written By P. Doyle, Boringville, PA on Wednesday, August 31, 2005

First off if any of your think these are "ok" or "alright" you must have problems. These subs are basically top of the line (aside the solo x line) these subs will give your more bass than u will ever need, unless you are a big bass head like me (My Philosophy: It's not loud enough until you have a headache for four days..or It's not loud enough bass until your nose bleeds.) if you are like me then you are gonna want at least 3 of these. You will not be dissappointed, you will charish your system. I have been fortunate enough to be able o work with these. For a car audio guy... these subs are truely a dream. and all of you who talk about you dB drag races and u dont really kno what u r talkin bout. Get a few books on car audio and study it. It will make u acctually sound like you are educated on audio. like the guy with the review that was say he hit no its dB learn your stuff. im 15 and i prob. know more babout this stuff. But thats beside the point, just a little warning. if you buy more than 1 of these u r gonna b spendin alot on amps and dont be suprised bout it. after you do all this, you will have enough bass 2 let the punks bumpin the little dual and polk and audiobahn systems kno whos boss and if they are gonna come to you, they will kno 2 come correctly. if you are lookin for even more bass i advise looking at the kisker solo x line (10" 12" and 18") these will prob. be the loudest subs you will ever hear and your will blow the comp. away. thanks for reading and puttin up with my grammar and good luck findin the sub that right for you (this is it)

livin loud 4 a little while

Written By Anonymous, Gambrills, mD on Wednesday, August 03, 2005

I had 2 of these hooked up 2 the new rockford amps, T1000bD, and handled very well for a little while, eventually the spider started shreeding and broke away from the cone, and one just got completly fried. They were good for a little while but just couldnt handle the power my amp was giving it.

Kicker Solo-Baric L7 04S12L7

Written By Nonameguy, Los Angeles on Saturday, July 30, 2005

These subs are by far one of the best I have come into contact with. I have gone through MTX, Audiobahns, Fosgate, and now these Kickers. The base itself is crystal clear sound, handles the 3000 watts I'm pushing to it with no problem. I must say though that if you are thinking about getting these subwoofers, you NEED to invest atleast $800 on car door speakers because the base will overpower almost any after-market speaker. I have two pairs of Power Series component speakers (6.5) with a Kicker 1200 watt 4-channel amp powering it and it sounds amazing. I also have a Fosgate Power series 3000 watt amplifer powering the 2 12'L7 kickers in a customer box. A power series Fosgate Capactior (1 Farad) and a Pioneer Deh-9600Mp cd player. By far one of the cleanest sounding stereos I have ever heard. And invest in Dynamat for 35 dollars and do your trunk, because it makes a world of difference to what people hear on the outside of your car.


Written By tightdog1, Clayton, CA on Monday, July 25, 2005

Ok i have 2 of these in a sealed box, in my 1990 Toyota Celica ST. They barely fit in the trunk. Recently they blew up my Crossfire 1000D. With he crossfire amp, the subs blew the sleals in the divider and broke the box. SO I bought 2 Infinity 310a, resealed the box with heavy duty silicone and insulated the box. I wired them at 2 ohms, so they get only like 347 watts total power each. Like half their max, of 750. They slap harder than they did ever before, Make sure you put bass blockers in your speakers cause these speakers can go loud and sometimes you cannot even hear your mids and highs! They shake my whole car, rattle the crap outta my trunk, and rattle other peoples cars so loud that they have to roll up their windows. My friend has a JL 12W7 in his Pontiac GTP and these 2 subs knock harder than that, with the recommended 1000 watt JL amp. Sometimes I cant even hear the mids and highs in my car becasue the subs are so loud, even with bass blockers, in the speakers.

super loud but no sound quality

Written By 1dude, dallas, tx on Friday, July 15, 2005

I purchased two of this a couple of months ago and let me tell you this subs are super loud. Have them on a 2004 Honda Civic with Boston Acoustics pros 5.1 in the front and the top of the line Boston Acoustics RM 6x9 in the rear pushed by an Alpine MRV 12. This subs came on a kicker medium size sealed box (from kicker). I'm pushing this with a RockFord Fosgate Power 1500bd. Be aware that this subs are loud but will not sound good in some types of music. If you like rap then this are four you. Since I'm not a rap fan I'm a little disapointed due to lack of sound quiality for the money I paid. I mainly play rock and some disco bass kinda music but this subs don't play every tone. The good news is that I have a friend that likes rap music so he is buying them from me. I will read the reviews of other subs on this web site. This tmie I will focus on sound quality and not on volume. Like I mention guys this are super loud but only for very low notes. Alos if you buy this make sure you by some dynamat. You will needed!!!

Great sub man i built a custom box ported a lil over 3 inches tuned at 53hz and ive had it 3 weeks so far and im hitting a 141db with an official mic and tomorrow i should be hitting harder at the competition going for a 142db with one of these and a 600.1 in an s-10 ext cab.


Written By Anonymous, Independence,Ky on Tuesday, June 21, 2005

I have two of these in a ported box in the bed of my truck, running off a PPI A-1200 @ .02 ohms stable. i can make the rearview mirrors of cars n front of me turn down, it vibrates so much that it shuts my slider window. the spray in bedliner keeps it from sounding like a tin can. I have over 12,000 dollars in all my system. those subs pushed my windshield out at the top 4 inches at my first db drag race. but i was disqualified `cause of that, but not disappointed. They are ungodly.

Nice Sub

Written By Emely, Los Angeles, CA on Wednesday, April 13, 2005

This is a pretty good sub. It replaced my to kenwood excelons. The only drawback to these subs is that you have to thoroughly break them in, really. If you don't, you have chances of ripping a part thats not vissible from the outside, i forgot the name. But whatever it is, it ripped in mine. So now i have a sub that does not sound right. But i guess it is my fault, hopefully it will get fixed soon. So when you get the sub, break it in for atleast a week or two! I know i should have.

the best subs

Written By chad t, Shelton, WA on Tuesday, March 29, 2005

Livin Loud

Written By Eric Snow, Martin, Tn on Wednesday, March 23, 2005

I have 2 of these running off a KX1200.1 and it rocks. I need to get it metered to see my actual SPL. Stuff rattles now on my car with the trunk open, that only rattled before when it was all the way up with the trunk closed. I am going to polyfill my box too. Dual slot ported. Box is probably a little small.

i love these bad boys

I have 2 of these in seperate ported boxes with a kicker sx1250 in a dodge intrepid. These speakers drop with little or no distortion at all I haven't heard a note that these speakers won't hit. If you want even better sound quality put them in a sealed box. You can't go wrong with these speakers.

This is the sub you want if you want to win competions! I've heard them in a couple applications and the bass that just one of these put out is incredably powerful. Its definatly loud enough to get some attention!

  • 2 Kicker stickers

Product Research

Enclosure Compatibility


Dual Voice Coils: For increased system flexibility, the woofer has two 4 ohm voice coils. When the voice coils are wired in parallel, the woofer presents a 2 ohm load. When the voice coils are wired in series, the woofer presents an 8 ohm load. In addition, each coil may be connected to a different amplifier channel and each channel will see a 4 ohm load.

Square Design: By making the Solo-Baric square, Kicker is giving you the most possible cone area (or Sd) for a given size baffle, 16% to 20% more area than a conventional subwoofer. More cone area means the Solo-Baric L7 moves more air, resulting in louder, deeper bass.

Cone Materials: An aluminum deposit impregnated cone is used resulting in greater rigidity for less cone flex and less distortion. In addition, the cone is also very resistant to environmental extremes. A rear cone brace provides added strength and reduces cone flex under stress.

Surround: The tough, flexible santoprene rubber surround has a long-throw, positive-roll design, which controls extreme cone excursion and is highly tear-resistant. The corners of the surround are ribbed to ensure linear cone motion. The surround is stitched to the reinforced cone edge, making separation between them virtually impossible.

Inverted Structural Dome: The Inverted Structural Dome replaces a conventional dustcap and locks into the cone for unmatched structural integrity and greatly reduced cone flexing/resonance.

Patented Enhanced BAM (Basket And Motor) Assembly: The cast aluminum basket features a low profile, open design to provide a solid anti-resonant foundation for the motor assembly.

Spider: The durable resin-impregnated poly-cotton spider provides precise coil alignment and critical cone motion control.

Voice Coil: The multi-layer voice coil and Kapton former create a superior magnetic field and effectively dissipate heat.

Chromed UniPlate Construction: The UniPlate construction combines the backplate and extended pole piece into a single unit to maximize magnetic efficiency and minimize alignment problems often caused by two-piece construction. The bottom of the UniPlate is chromed to provide enhanced heat transfer for cool operation and maximum power handling.

Bumped Back Plate: The deep bumped back plate lets the voice coil reach maximum excursion without bottoming-out.

Perimeter Venting: The perimeter venting cooling system continuously pumps hot air away from the voice coil, replacing it with cool outside air.

Gaskets: The one piece front beauty ring and separate one-piece rear gasket insure an airtight seal and provide enhanced cosmetics.

Rubber Magnet Boot: A black rubber boot covers the outside edge of the magnet structure to improve the cosmetics of the woofer and protect the magnet from chipping or breaking during installation.

Tinsel Leads: The speaker features sleeved high-power tinsel lead wires to resist breakage and power-robbing resistance losses.

Speaker Terminals: The terminals are spring loaded and nickel-plated for solid connections with speaker wire up to 11 gauge.

Break-in Period: Due to the complex nature of Kicker Solo-Baric L7 speakers, they require a break-in period in order to produce optimum low-bass response. The high-performance suspension system makes the speakers very stiff "out-of-the-box". Approximately 2 weeks of daily playing will allow the suspension to break-in and reach its optimum equilibrium. A "broken-in" subwoofer will exhibit stronger bass performance, smoother response, and greater low-bass extension.

Enclosure Compatibility

Power Handling: When the subwoofer is mounted in a sealed enclosure that has a volume from 0.88 cu/ft to 2.0 cu/ft, the woofer can handle up to 750 watts RMS. When the woofer is mounted in a vented enclosure that has a volume from 1.75 cu/ft to 3.25 cu/ft, the woofer can also handle up to 750 watts RMS.

Recommended Sealed Box Volume:

  • Compact (minimum enclosure volume): 0.88 cu/ft; the woofer can handle up to 750 watts RMS
  • SQ (maximum enclosure volume): 2.0 cu/ft; the woofer can handle up to 750 watts RMS

Recommended Vented Box Volume:

  • Compact: 1.75 cu/ft; 2.5" x 13.25" port opening; 22.5" port depth; the woofer can handle up to 750 watts RMS
  • Street Bass: 2.5 cu/ft; 2.5" x 13.25" port opening; 16.5" port depth; the woofer can handle up to 750 watts RMS
  • SPL/Deep Bass: 3.25 cu/ft; 3" x 13.25" port opening; 14.5" port depth; the woofer can handle up to 750 watts RMS

Note: The power handling specifications listed with the vented enclosure recommendations apply only when a 25Hz, 24dB/octave subsonic filter (sold separately) is used with this woofer; if a subsonic filter is not used, the power rating will decrease and excessive port noise can occur. 

Cutout: The woofer will not mount in a standard enclosure with a round cutout. Instead, the woofer must be mounted in an enclosure with a 11.155" x 11.155" square opening.


Manual Note: The specifications printed in the manual are for the 2 ohm model. The 4 ohm model specifications in the Crutchfield database were obtained directly from Kicker.
