I currently have a 12" FI BL in my car with a US Amps MD1D. I am looking at maybe putting another one in and I have a few questions. How big should the box be? FI recomends 2.5 cu. for one so when you have 2 do you double that? I have a dual 2 ohm so I would get another dual 2. I have a Hifonics 1206D sittin around so should I use that or buy a amp that is .5ohm stable? Like a Lazar Opti2000D. Or a big amp that can give around 2000 watts at 2 ohm. Would I need a bigger alt. current one is 120amps and I have a Kinetic 1400 batt. in the front and am going to look into getting a smaller batt. for the trunk.

Im in need of help on decision making... I just finished my wall in my car heres the details 2001 cavalier 2 dc xl 15's 8.4 cubes after dis. going to be tuned right around 36 hertz thats were i need help before i cut the holes for subs and port i need some opinions on which setup to do one sub behind each headrest and port in the middle of subs, above the subs, or below the subs.. also maybe putting one behind passenger headrest one in the middle and the port at drivers headrest which is personally the one ive heard is the best for TL numbers any opinions are helpful thanks in advance

i have the big 3 ,,0 gauged on all points , also have 0gauge ran to mount area and 0ground under 3feet,, i have a 300amp fuse, am i doin this wrong, i plan to run the amp down to a 1ohm load daily ,, will the 300 do well or do i need to step it up to a 350 or bigger,,

Where can I find a reseller of Treo amps and speakers? I have Googled twice, and came up with nothing. I just want to find out pricing for now, as Treo are a bit slow sometimes with responding. Thanks

I have heard before that port noise can be increased if the port is too close to the sub. Is there any legitimacy to this?

so i see occasionally people mentioning Audacity to check what kinda hz some songs are hitting, can anyone link me to a decent video that will teach me how to go about that? i did a quick search on youtube and i couldn't find anything. i didnt try google cause my internet decided not to like google right nwo and take foreverrrrrrr to load. so could someone please tell me, or link a vid, something to help me out here.

Anyone else going? Two of us from Audio Junkies will be there all day Sunday. I'm sure I'll see a bunch of the Fi guys there. If anyone is going to be there competing, give me a shout and I'll be sure to get some pictures for you.

Hey guys im about to order dual alts for a 03 tahoe. Do i need any extra pullies and also is the belt included? Im gettin it from Dom at Iraggi and hes not replying to well to emails. thanks

I am building a box for 2 SA-12's for the trunk of my altima. I want to have a square port between the 2 subs on the front of the box, looking somewhat like this: O | O sub port sub Using 3/4" MDF and outside dimensions, my box's height can only have ~ a height of 16.5", a width of 33", and a depth of 16.5" (however, the depth can be altered a good bit if needed) I need to know what dimensions to make the port and the dimensions of the box itself if anyone could help. Thanks.

Okay. The box is 4 cubes @ 31-32 Hz for an Fi Q15. The box is strangely shaped because a spare tire is going to be standing up vertically behind the box to the right of the port. This was my plan. I was going to add 2 more vertical 2x4's to the right and left of the sub hole. The baffle, port, and vertical brace are NOT permanent yet. They haven't been attached yet. That's what's permanent. I was told the back wave is going to be fed directly into the port and that usually doesn't work well. Should I change my port? Anything else?

Well i can hear the Bl is reeking havoc on my box when it hits the low notes i can hear an air leak even with a monster port. Thing is id like to be able to have to option to move from one 15bl too two down the road. Question is do i build 2 separate boxes and just leave one out for now or do i make say a 8+cuft box and run one in it for now. I don't think that would work considering the port area would be to large for just the one sub right? Anyways i got a 21.5xin40inx26in (HxWxD) space to work with and i can barley manage it but i can get two 21x20x26 boxes with 4.01cuft after displacement and tuned to 32hz in there. what do you guys think i should do?

I only have a 60 amp alt. and i was wonder if it's okay to put a second battery in the back of my car like a kinetik hc 1800, will it be able to charge my stock battery and the second bigger battery in the back? i'm just running 1000w rms. i'm thinking of a second battery because i'm planning to get a new car next year, so a second battery will be easier to transfer to the new car, then a bigger alt.

I can't believe i am making this thread but there is something not right and evidently i have forgotten. I had this problem before but it was like 4yrs ago and i cant remember what i did. Ok here it goes- I have a sundown 100.4 I am playing a 600hz tone. I hooked up a speaker to chan 4 only to make sure it would output power, it does fine, i even played some music on it so i know the amp works fine. Now, i connect the probe from the oscope to the positive terminal of chan 4 and the ground clamp of the oscope to the negative of chan 4. When i connect just the positive, i get this crazy wave form. When i connect the ground clamp, ... nothing changes. If i connect the groun…

So i have been looking at forum posts lately and i have come a across a word a few times and i don't fully understand it and i was wondering if someone could help me out! the word is "going active" like what does that mean? i have heard that before in movies but when i hear it, it doesn't mean anything good. so i thought i would just ask a noob question and maybe get lol at or be the bright point in someone's day!! thanks for helping Kenneth

can you just add an optima to your current system wired parallel. you would still just get 12v. or 13 whatever. but it said charging a deep cycle bat is a whole different thing. an it would just fry your alt. high output or not??? help please thanks again

anyone ever place a order with this guy? if so how was the box and the shipping cost?

I have my kenwood excelon 4 chan mounted in front of my sub and port... I think the vibration is the reason I had to get the digital processor replaced on the amp and kept giving strange errors on the display. we tried larger head screws and my next option is rubber washers to stop the amp from vibrating so much. or would it be smart just to forget about the amp and jump on the pre order for the sundown 100.4. has anybody ever heard of that problem before?
