Summary: I had a custom-made box by a local shop that deals with supercars also. But it is no match against JL audio sub that was in a Bentley. Hands down, you can hear the big difference. Sorry that I dropped a lot of money for this square thing. If it looks like a square, then it will sound as square as it can be...
Pros: different looking
Cons: I you love your ride. Find other subs that will make you love your ride more...
Summary: This sub just doesn't cut it when it comes to sound quality. I really tried to liked the sub and spent hours trying to tune it to my liking. Don't get me wrong this thing thumps but it sounds awful. The square cone pushes more air but isn't as responsive as a 12 inch round sub. So if youre into dubstep and other terrible music then this will be fine for you, but if you want clear precise bass this isnt what you want.
Conclusion: I will start by saying I had 2 08S10L74 before I upgraded to to these. The 12's are worth the upgrade if you have the cash. I have them in a 3 cu. ft. ported box, 1.5 separated chambers. These subs will take anything you throw at them. I listen to rock, rap, country it all sounds good. These subs give punchy bass but also hit the lows and carry them very well. I have them hooked to a 1500w amp and they seem like they want more. The only draw back is the price.
Conclusion: These subs are very durable, they are rated at 750 wrms, I have 2 of them wired down to 1 Ohm and I am also pushing them with over 1988 watts. They sound very clean and pound the hell out of my accord coupe. These are a great buy for someone not wanting to spend alot.
Conclusion: This sub really hits all of the low notes. I have it in a custom box tuned to 32hz and it shakes everything. It is paired up with a hifonics 1000.1d and it is amazing. I had the 2004 model for 8 years then I upgraded to the newer one. Great product!!!
Conclusion: I just purchased two of these monsters and a powerbass 3000 (1500rms) all wired up in a dual ported box 2.5 sq for each and all I have to say is wow I have owned many systems in the short 5 years I've been driving and this by far is the best I slam on my buddy's three type-r's so for all you alpine lovers bring it. These subs slam the lows like you owe em money haha but come back and nail all the bass notes as well all around great woofer.
Conclusion: I've had my 12" L7 since December and this thing is nasty. I have it wired to 2ohms running at 1000w with an Alpine MRP-M1000 and lemme tell you i've impressed all my friends. I love my Kicker, its in my 2002 chevy trailblazer and people who sit in the back say they cant breathe when this things pounding. Now it doesnt set off car alarms cuz that just doesnt happen but my friend has heard me comming home when he was in his basement.
Conclusion: These subs are horrible. They are slopy. Yes they're loud definitely but its not musical it's just vibration. Its SQ is horrible SPL is up there but musically they suck, and the way they're made is not great quality. I had this switched out to JLW6 and they sound a lot better than these.
