I'm about to start my first ported box as well but I'm still in the learning stage. What is 'port noise' ? Box looks good, hope my build will run smooth too

There's always the option of doing one or two 10" subs. The 10" Q's don't require nearly as much volume. Would that work or would it not really give me what I'm wanting? Sean, I PM'ed you about an amp too.

i see what you mean.... do you know if it has been done (correctly)?

I can weld something to extend the tabs if need be so that should not be TOO big of a deal. Now, using other people's calculations is not ideal but Subthump boasts that their box has 2 cu ft of internal volume so i SHOULD be able to get at least that but you are right about there being a big difficulty in being accurate. If it is a big deal, i could make a cheap 'model' of my box with ply wood instead of MDF and fill it with water and get the volume that way but that is probably too much effort and money (have to fiberglass that too). You still say I should build the port with MDF right? I think you sent me some links in another thread but do you have anything that will show me how to build the port?

I figured I would have to throw some washers down or something to raise the seat. The problem is that I cut the back tabs behind the seat to allow the back to fold down. Because of this, I'm limited to how much I can raise the seat but even raising it 1/4" will give me another .1-.2 cu ft and every little bit will help. How will upfiring change the sound vs downfiring? Either way, girls will enjoy sitting back there I suppose. Then, how do I go about choosing an overall port area? You are sticking to me using MDF for the port, right? Do you have any pictures of some boxes you have built so I can get an idea of what is going on?

You are probably right. Although, I am going to buy used most likely so I might just take what I can get.

I'm hearing tons of good stuff about Fi but I'm not sure which of these subs will fit my tastes best. I'm shooting for one 12". I like deep loud bass for my reggae and even for 'metal' . I like it vibrating the hairs on the back of my neck loud. But I listen to a lot of punk music which would need some good SQ especially for the double bass (not many subs keep up with it well). So, I know that the BL is the SPL sub, the Q is the SQ sub, and the SSD is kind of an entry level mix, but which would best fit my tastes? I can only afford one sub I only have 2 cu ft to work with. I figure I'll be best with a ported box tuned @ 35 hz (a little high to help the punk music). What you guys think? What options are 'must haves' on each type?

I also need to fiberglass to save some mounting space. From what I gather, the Fi Q is what I'm wanting for my setup but because of my limited mounting space I might be forced to grab a SSD or BL. you guys mind walking me through the basic build process of doing the ported box? I got winisd so i know ill need to do some calculations to get the size of the port. Obviously I'm just confused on what is going on inside the box. I understand the concept of directing the flow to the port but that's about it. I'm Brandon by the way

Yea i saw they are rated at 1000w rms. I am cheap but definitely want the most for the money. If $40 will gain me some extra wattage then im all for it. How much power is ideal for the sub w/ bp power as a daily driver? I've heard people pushing 1500w but what is ideal? Don't want to risk blowing the sub. Well if you aren't cautious about it you will blow it with 1000w....just a 'for instance' i've got a little over 900 watts per side in my component system in the 4 runner, granted i don't use all of it, and with those little coils of a 1" tweet, 3" midrange, and a 7" midbass driver..they will not take that kind of power. There's nothing wrong with headroom, you just have to know how to use it, and not abuse it. Your amps have to be gained in right to match your headunit's RCA voltage...the subsonic filter(s) have to be setup properly... We rate them so that you will not hurt them given the worst possible scenario, granted if you abuse them and play volume master and gain master odds are you are going to blow them... Thanks! Makes sense. So assuming I don't get greedy with the volume/gain, what power should i shoot for w/out Bp power and w/ bp power?

Here's a picture showing what I mean: http://edesignaudio.com/im2/boxcuts/12%20rec%20vented.jpg I'm talking about everything going on inside the box

My limitations are 2 cu ft of space and only about $200-$250 for an amp to match the sub Would you say the BP power is important to get? What does it really do?
