What amp, what size box and everything else you can think of to tell us the difference between your friends and your's and we can give you a better decision.

As far as we know you have a 1000 watt amp and your friend a 100 watt amp?

I've seen a 10 beat a 12 inch sub but of course they had a much bigger amp.

Actually, from my understanding the 2006 L5 is about 2db louder than the 2006 L7. With the same amount of power, same box dimensions.

Well you are very close young grasshopper, there is more to add to this.

The 2006L5 is louder then the 2005L7 by .3-1.5 decibles. The 2005L5 is louder then the 2006L7 untill you get to around 1400watts then they are about equal.
The 2006 L7 gets louder with a ton of power and will hold together, but the L5's give out at around 2500watts per woofer.

This is a PURE SPL test only.    3 second tone burps

My friend has an L7 with a 600watt kicker amp.
Im not sure how big his box is.

I have THIS L5 AND THIS BOX I found someone to buy my L5 so im looking into buying an L7 and putting it into the box that my L5 came in, im also running a 600 watt kicker amp.

I will say it again, with your L5 in a custom built enclosure....look on the kicker website at the manual for your sub, you would easily beat a L7 with the same amount of power.

Trust me on this.   I have tested it and the new L5 will beat the L7 up to about 2000 watts per woofer, then the L5 just cant handle it, but the L7 will continue to get louder.

That is just in a pure tone secenario, but I know the drop in test we did with (1) L7 12 Vs an L5 12 was quite surprising with one sub powered by one kx1200.1   The L5 was close to 2 decibles louder with both music and tone.

The one big reason i want an L7 though is because is can handle more power, i mean the last L5 I had I blew, and now im always worried about blowing it. Are you saying that my L5 in that custom box would beat an L7 in the same box or what? Jeff do you have msn or something because im not sure im reall understanding all this stuff

On the amount of power that you both have, the L5 will beat the L7.   The major factor right now that I see is the pre-fabricated box.   With the amount of power that you have I dont see why you would ever blow a woofer unless it was being clipped horribly.

We have been running a single L5 for about 2 months now, powered by a KX1200.1, and seen no problems what so ever from it.

OK so from what your saying I should stick with the L5, Your probably right about the clipping problem cuz this is my first system and I installed it myself, it was clipping because I couldnt seem to find a good ground with the first speaker i had, now the speaker I have currently seems to have a problem with the surround, and crutchfield feels it is because im overpowering it, they said they will exchange it though.

Take a look at the surround, its is coming out from under the edge of the speaker:

In the left pic is what it should look like and in the right is what it looks like right now:

I had some problems with surrounds, but it was my own fault....I left the woffers in the garage and they ended up getting alot of moisture in the boxes.

The glue didnt hold up to long.   As far as clipping goes, the Kicker woofers are horrible about tearing themselves apart from it. so please please read the gain turtorial at the top of the fourm.

The L5's are a huge improvement this year...in all actuality the 06L5s are basically as beefy and nice as the 04-05 L7     The New L7's are really really nice, but man they are startin to get power hungry!   The bigger rewound coils are alot more giving on long use and clipping. The cones are much stonger!   At nearly 3000 watts per 10in woffer I have in my comp car I still am yet to crack a cone.   But on the 12L7's of 04-05 you could crack the cone at around 2500

Stick in the 06 lineup...if you really want to exchange, maybe consider going to a 12 instead of a 10...but I have been very impressed by the 10's so far!
