Whats the problem!?!

[Wildbillpb 10+ year member]

I have two kicker l7 15" that are not getting as loud as I expected. I have them hooked up to a lanzar 282 (shitty amp) bridged which I am guessing the amp is probably pushing 800-900 to ea rms with 0 guage wires. The thing is they are not as loud as I thought they would be I have heard two 12" l5's get louder. I have not been in the car audio for a while and I came back and bought what I knew but they are not doing what I thought they were capable of I had two p2 12" 4 years ago that were louder. So is it that the amp is THAT shitty that it is that bad or could it be my box? My box was not caulked when I got it. Could it be a leak? Should I go back and caulk it? Also, I have the voice coils wired in parrallel and the speakers in series, which is a 4 ohm load. I did not think that it would make a difference but should I go back and wire the voice coils in series? One last thing, could it be the way my cars trunk is? It is a 94 lincoln town car so there is a shelf in it where it dips down into the bigger portion of the trunk it looks like this :

Thats not my actual trunk but it is the exact same. Should I flip the woofers to face up or should I leave them facing the back of the trunk?

Box tuning? And Specs?

Usually, its 10% the sub, 90% the Box.

Not sure bought it from a sub shop it looked like the standard l7 15" sub box i'll post pics in a bit

Let's see...

Are they DVC 2 ohm or 4 ohm? How are they wired?

Oh, and I don't care what the "specs" are on that Lanzar amp. It's not pushing nearly as much as it claims.

That's how they are wired.... and it doesn't claim 800-900 it actually claims 4k watts lol

That's what the box looks like. I got this picture from the internet it is not the same one I have but it is close. I did not get it from sonicelectronix and the box in the picture is caulked mine isn not. Also, the terminals on mine are in the back not on the side other than that it is pretty close.

Think I should just spring for a kicker box or are they just overrated?

Could it be because there is no divider in the port like where the port is it goes back it's just open space so it's almost like it's just one big

box

Yeah it claims 4k watts max. Seriously man I think it's just your amp. I'm definitely no enclosure expert or anything so I can't give you the ultimate advice there. Not trying to insult you or your equipment, but Lanzar products just do not perform.

this

ill put $100 down saying your box is the problem looks like you have just a basic prefab box and from u saying it wasnt caulked more than likely it is a pretty shitty prefab

I know, what I am saying is it claims 4k watts and that most people say it is doing more like 800-900.

Sould I try caulking the box or getting rid of it and just buying another?

Trying to find the ones that kicker themselves make so I do not get screwed again but I cant find them does anyone know where I could buy a kicker made box?

well the best thing to do is make a box that goes for those speakers... alot of people dont realize the box makes the whole sound system( or atleast the subs)

 

[Wildbillpb 10+ year member]

I don't know how to make boxes I would kind of like to just buy one I don't know how to "tune" them and what not.

 

[DammitJames 10+ year member]

find someone who knows how to make one then dont waste money on prefabs
