The subsonic filter is for a ported box, not sealed. It keeps the speaker from going to far below the boxes tuning freq and over doing itself. (in a general way of looking at it).

you just told me what i wan it to hear. u ask about the box i know someone on the internet that those boxes for kicker subs suposly they get the specifications that kicker give them and make the boxes so the subs can perform the best. about the frequency on the amp y 50 it depend on the size of the sub for that setting or 50 for sq how does it work i dont get that. and what about the subsonic thing what is that for. one more question the setting on my head unit where should i set the bass someone told me negative 6 but i am not sure about that i would say 0? so u think that those 3 r gone a hit better than 2 12.i dont care any more about sq everyone in here told me kicker is not for sq so like i will stay with kicker and my choices r those i wan what ebver it hit the most thanks for u help everyone

ok, the 50 to 120 is the crossover points for the sub. I would crossover the subs at 50hz..go with 3 in sealed, should be a smaller since it is a sealed box, audiobahn aren't really sq amps, but they should do you justice for what sounds like your needs. Three subs will hit like no body's business, but more than likely won't be much like a sq setup.

Either way, go with what you like. You're the only one who can make your decision. btw...where are you getting your box from. If possible get the box built from a local shop or from some of the guys on here. Going from what I have read from previous posts, it might be a better route for you to let someone else build your box. Don't take offense, I have people build my box and I used to manage a stereo shop. There are reasons people install car stereos for a living. Trust me. Good luck in your findings

Pedro, for the love of all that is holy, PLEASE construct your posts better.

Better constructed posts receive more attention and better answer.

BTW its ran not wan and eventhough not 'eveo doe'

mmm i am sorry man my english still bad jajaj u know i am mexican my name is pedro.... about the amp i have an audiobahn amp A8002T is gives me 400 rms x2 at 2ohms and i am gone a get another A400T its a mono amp 400 rms at 2ohm so that would me three speakers going 400 rms each one i know i can fit 3 sealed box the with 10' speakers or 2 12" onm ported. aaaaa so u tell me the hz of the box does not have to do with the frequency on the amp. i get that part... will another real fast question i i have 2 12 on the car right now if my amp says 50 to 120 on the frequncy how do i know what frequency should put i think i read on 12 inch subs should be on 80 but i am not sure and the sub sonic says 20 to 50 how do i set the setting on my amp? thanks guys for helping

ummm Pedro....slow down when you type first off. Judging from your post, I would go with 2 12's since the box would probably be smaller since you have a small trunk and such. I wouldn't go with 3 subs cause that can run the amplifier at too low an impedance. You didn't mention what kind of amp so I won't even try that...but tuning a box to a specific frequency has nothing to do with an amp, but it has everything to do with how your subs will perform.

will all of u guys talk about kicker like there shit subs i am ono expert i am bearly starting with my second system i start an yeah ago with some sony subs than i bought a kicker l5 and it was much louder than those 2 12 " subs and the sound quality was perfect for my little trunki it was inly 1 12" sub and muche better than those 2 sony trash ass subs so thats y diside going by kicker subs. WILL NOW I have 2 12" comp vr subs on their original enclouser they sound loud but the box does not fit on my trunk eveo doe i oinly giving them 400 rms to both of the cause the way they r set up on the enclouser ok so i can bearly fit the box on my car so thats y i need to change my system since i am one of those guys that we wan everything i need more so i wan louder subs and better sound quality. i wan the l5 subs and i know where to get then ship and new tghats y i wan it to stay with them a mean i dont wan the best of thje best subs i just wan some thing that sound kind of loud and clear music i drive about 3 hours every single day so i realy enojoy my music so my question keeps the same so what u think it better 3 10 or 2 12 at least tell me that kicker its an all right brand i would feel better after reading all ur answers. one more think i dont understand when u guys thalk about the boxes about tuned as 45 hz ior 35 hz i dotn get that is that has to do with the amp thanks.

I'll add the RE SE to that list as well. They sound damn good..There was a thread over at SI.net where several people thought they were in line with the W6v2 as far as SQ goes..and a little louder.

Depends on the SQ you want

SQ when loudness isn't a big issue:

Dynaudio MW190
Image Dynamics IDQ
JL Audio W3v2, W6v2
Focal subwoofers
Eclipse Aluminum
SEAS Lotus

Note: JL Audio W6v2 and Eclipse Aluminum do get pretty loud, but their are subs in their lineups that are louder. Both are excellent at lower volume levels.

SQ when you want loudness:

Image Dynamics ID Max
JL Audio W7
Adire Audio Brahma
Resonant Engineering XXX
Diamond Audio subs (D9)
Eclipse Titanium

I wouldn't recommend anything Kicker for SQ.

I can vouch for Kicker's L7's being crap. I just successfully killed my 6th one.
I might also look into image dynamics woofers also, along with the aforementioned woofers.
