The Kicker Solo-Baric L5 woofers inherit all the same patented technology as the dominant L7 square woofers at a more affordable price target. The 08/09 series offers a hot new look and improved design, specifically with the new SoloKon technology and heating disbursement. The patented square design allows for 18% more cone area, which translates to more sound compared to competing round subs. The SoloKon one-piece, injection-molded cone offers full-coverage back bracing that pushes more air and creates louder bass than ever before.

The Santoprene rubber surround of the L5 handles the power of the motor and cone, and a rear foam gasket secures the stamped-steel basket to any given baffle. The logo-bearing steel basket with spring-loaded terminals, a stout magnet, and the logo-bearing protective front gasket also allow the L5 to take on power like never before.

In a slot ported box, BANGS!

I am only running a 300 watt amp to this for now because 1, its winter(freezing temps) cuz I don't wanna over work it and blow it cuz everything is so cold, and 2) its fairly new so I wanna break everything in for the first 6 months but shoot! This thing bangs so hard already I don't even know if I wanna upgrade my amp to the ZX750. This is plenty for me...

Great Sub

I bought this sub almost 2 years ago and its still going great. I have it powered by a Kicker 500.1 (actually rated at 609 watts RMS). I first had it in a 2 cu.ft. sealed box that I built using the proper materials and it sounded failrly good. Response could have been better, volume could have been better, and high notes could have been better, but it hit low end notes really well. So I decided to put it in a 1 cu.ft. box, which I also built and did everything but the size the same. Everything improved (except volume). SQ is great, response is great, it hits really hard, and it has good range. However, if I were to buy this sub again I would port it right away. I'm very pleased that I bought it, but I think a ported box would really show off its SPL potential. If you're going to have a sealed box for response and SQ, you might be better off going with a different sub, and probably not a square one.

Truly an amazing subwoofer

I have installed over 50 audio systems in vehicles and have put together systems for friends and family for many years. I had read about and always wanted to try a Solobaric and finally got my chance to install one in my wife's Camry. I had to keep the cost down on this one so I went with the L5 and 4ohm to bridge down to 2ohm. I designed and built the box at 2.0 cubic feet for the SQ type sound and picked up a Fosgate Prime 500 to keep things on the economic side.

The sub is very efficient and butter smooth. The lower freq's just flow out like butter without that rough, vibrating sound. I doubt that I am pushing more than 200 watts RMS through it and it makes my wife wiggle around while the rear view mirror is useless and this is with only one speaker.

So, this is one truly awesome sub and by far, the best that I have ever installed. The unit's build quality is very good. I can only imagine the sound if I hooked it up to my Fosgate Power BD500. From this point forward, it will be Solobaric's for me.

Great buy

I just ordered one of these guys and I'm very happy with it. I can't wait to order the second one and I am thinking about adding a third. Great choice for anybody that's trying to beat down the block!

good sq

someone said that this sub has no SQ but they are wrong i have a bass worx SQ ported enclosure with a hifonics brutus running at 2ohms 1100w rms but the key is to run the bass eq a little higher but dont crank the gain. and im running the frequency at 100 on the amp, the sub hits every note thats thrown at it.

Pretty good sub

I had this baby hooked up to a MTX ta5601 @ 2 ohms in a 2foot box tuned to 32hz and it was loud. If you want SQ i'd buy something else but if your going for raw power and loud-ness by this or if you have some extra cash an L7.

WOW L5 hits so CLEAN

I have 2 12in L5's in a sealed box 1.3 per sub in my single cab Chevy. With Rockford Fosgate P1000.1bd amp wired down to 1ohm. They hit so hard and clean I had to buy better speakers because the bass was hitting so much louder with only half the volume up. Did I mention they hit very clean with the proper box. These are the best subs I have ever had and heard plenty. Wish I would have bought these sooner!!!

They are loud and take serious abuse

I have 2000 watts rms going to two of these in a ported box I custom built to kicker spl (big ported box) specs. When I turn the bass all the way up for about 30 seconds I can start to smell the subs from the ports. When I play it for more than 45 seconds, I can start to smell them from the front seat. This is only when I am playing it at full volume on very low frequencies. I have done this quite a few times and they still play like new. Keep in mind, I am running these at almost double their rated power and they are still kicking after a full year of this kind of abuse. Remember this is at full volume, which is when nobody including me can even stay in the car for more than 10 seconds. When it is all the way up my vision blurs and breathing becomes a challenge. I have heard many cars with the same amount of power and none have been equal including a soundstream sponsored truck with more power. So far I broke the back wiper off the back of my suv and made the rearview mirror fall. When I played it in the garage some boxes fell 10 feet away and drywall dust fell from the roof. I have the doors moving about a 1/4" with the windows up or down. When I pulled up behind my friend at a stoplight, he knew exactly who it was instantly. I bought mine for $300 for both so these are cheap at $130 each. I highly recommend these subs.

Livin' Loud with Kicker L5

I bought a used 2 ohm version of this sub and have not been let down yet! I have it wired in series at 4 ohms on a Kicker KX600.1. Since the sub is wired at 4ohms it is only getting 300rms from the amp. I built a custom sealed box because the kicker sealed box was useless. This sub is in the back of a extended cab Isuzu Hombre and it gets stupid loud! I've been installing systems for years and this is hands down the loudest 12" I've heard on half of it's rms rating. Kicker has yet to let me down!
