Sent you guys an email like a month ago, never got an answer. My email slim142 at h.o.t.m.a.i.l Was asking an approximate for a box for a single 12" ported tuned to 32hz and shipping cost to 33160

I didnt know that you are suppose to set your subsonic within 5Hz of the box tuning. So no matter what sub you have, and no matter if the specifications say sub handles 20hz-150Hz, you never set your amplifier to 20Hz?

Dont want to steal the thread but When you want more Bass, its better to go for more cone area than more RMS? Considering we are talking about Fi and their line of subwoofer only. Considering same size, 2 SSDs would be better than 1 BTL even when the BTL has more RMS?

Ingloriouts Basterds sucked so much. I hated that movie. Wanted to fall asleep, long, and just bad. Liked like 5 mins out of the entire 2:45

Ok so Back again I have a story to tell and I need recommendation ASAP. So I have my subsonic on what looks to be 20Hz on my 2000D (half is 25Hz so a bit less), so I decided to see how good can my subwoofer handle the low note on Put On by Jeezy. For my surprise.... As soon as I played the song (from a normalized volume CD with 75% volume) the very begining has this low frequency that made my sub make this super strange noise! Im going to try to describe those 2 seconds of HORROR because I thought I could have killed my sub in just seconds. I had my bass remote up. Started playing song. Sub started going up and down like crazy but this time it sounded as if the cone wanted to just launch to the roof and separate from the spider and this sound that came out of INSIDE the sub was.... imagine a huge piece of plastic (or thick paper) bending as a parabola up and down. I hope Im giving a clear idea of the sound. Now, I did bring up my subsonic even more this time. Its almost on half right now. But Im pretty sure my gain has to be decreased a notch too. I just want to know, is this song really suppose to make your sub make weird noises or movements? I know is hard to explain without a video, but I really wouldnt like to record it playing this song at least for now.

Does having anything thicker than 1/0 gauge really gives a noticeable improvement? Is it worth going 2/0 or 3/0? Where do you get this thicker power/ground cables?

Hey guys Sorry Ive been kinda busy and didnt really have time to make a video of the sub. Will definitely try to make it tomorrow and hopefully show you my set up. On the other side I have one question. My ford expedition came with a factory 8inch sub (which is where my 2000D is getting the signal from with a LOC) and it is located above the rear-left wheel. My question is, should I unplug the factory 8inch sub and just play the 12" pioneer? I have seen threads where people wanted to mix 12s with 15s and 10s and the answer was NEVER DO IT. I would like to know if I should unplug my 8inch sub. I havent disconnected it since its factory, I didnt think it would affect my system sound, but just want to hear some feedback from you guys. The 8inch is nowhere near my 12 and is mostly covered by my tools and materials that I have in the trunk.

I see, thats was clearly explained. I thought the term bigger the better applied just to everything. I guess I will stick to 1.25 to keep it to recommended manufacturer spec. This will be my practice test so I know how the process works so when I order my BTL im enclosure ready by the time it comes

May I ask what are some facts when it comes to building your own enclosures? Things that you MUST do regardless. Also, I want to use 45 angles on the corners. Does it improve things a lot? Finally, should I use double thickness for everything? Just the front (sub+port) side? or no double thickness at all?

Oooh ok, well then in that case I guess 1.25 is what I should follow since thats what Pioneer recommends for the TS-W3002D4 in a ported box. The tuning, you can have it at any frequency you want right? There is no "perfect" tuning for subs.

Hey thanks for that info At the beginning when I didnt know much about car audio, I thought that following manufacturer recommended enclosures was right. Then I starting reading a lot of people saying that the bigger the box, the better so I kinda disregarded what Pioneer recommends. Why is it better to follow the manufacturers recommendation in this case? Cause Pioneer recommends 1.25 for my sub and thats exactly what you have yours on. Doesnt the "the bigger the box the better" term apply in my case? if so, why?

Hi It just got to my head that I should probably get rid of the box I have and make one myself. The one I have was bought from a shop and I dont even know what it is tuned to or the cubic foot. From the outter measurements, Im calculating 1.75-1.80 cubic foot. Here are the measurements of the current box I have my Pioneer TS-W3002D4 Well, basically I want my own box so that I know the exact tuning and size. First, I would like to know if its good to have a 12" tunned to 32Hz since thats what I want to have my box tuned at. 32Hz with ~1.80cubic foot AFTER subwoofer displacement. I would prefer to have subwoofer AND port facing the same way and box measurements ~15-16inches the width, length and height. I will put the audio connection in the opposite side of the sub. Going a little bigger could help but unfortunately I dont have the space right now, but Im pretty sure 1.80 after displacement is more than enough for a single 12" right? Also, what materials/tools do I need? 3/4 MDF, the audio connection, screw driver. Thats basically what I know is a must.

Cmon bro! measure it so we know how much you hitting! loll I would say 160dbs but, thats just an estimate.

Ok like many others, I just jizzed here. 10/10 when it comes to products, quality, detail, work, and finish product. This is just KICK-ASS and even that doesnt describe how AMAZING, GLORIOUS, and INCREDIBLE this build is. I think the guy from the Tahoe just got the 1st place taken away. Some questions though Can we please have some numbers? I would REALLY like to know what you hitting with that car. ~160db should I say? Also, how come only 2 alternators? Car limitation or you feel good with only 2? Sundown 2000D would have been great there, but those S-2000D still look and seem to perform great.

Im pretty sure most people here will agree that LPF on 80Hz is ideal, but at the end it depends on taste.

I have pushed my 12 to the max and Im still not bass-satisfied.

Ok yes I think it will be better to take a video with some songs playing. But I can tell Ive almost got my gain right, Im starting to have more control over my sub.

Dam would love mids and highs. Im thinking about getting Alpine Type X but those are getting old and what better than Sundown for everything?

May I please know whats the difference? Technically, 10 Hz If you used 60 Hz. you would end up setting the gain too high. Haha, I think the technical part is pretty easy to get at first sight Ok then, will look for that user with the free sines again and download his rar package to get the 50Hz.

May I please know whats the difference?

Does a 60Hz sine count? or does it have to be a song? I was planning on doing it old school. Burn a CD with JUST the 60Hz sine 0db with volume normalization (dont think it will apply since its only one song, but just for sakes ill enable it) and have it play so I set my GAIN to what I think its a notch below the stress point.

Hmmm thats where I had my ideas wrong. I thought there was such thing as "Perfect Gain Setting". Guess I was wrong.

Well considering is a ford expedition, does it make the difference if I open the trunk or not? its not like a sedan where the trunk is "sealed". Usually, when I stress subs I get the thermal limit sign. Has happened with a pair of subs already. Mechanical I really couldnt tell if I have/am experiencing it. When a sucked in cone happens, does the sub still work? My pioneer is harder to push in (using hands) than my kicker used to be. It might be the different brand though. My pioneer still works and plays good. About the box size, it was ~1.75-1.80 with outer measurements so I heard true volume should be ~1.40 minus sub displacement ~1.30. Pioneer recommends 1.20 for ported so I should be good there, but my box is bought from a shop and Im pretty sure I can get a lot more performance if I build my own but right now im not in a situation to do so. I want to mention, I burned a CD with 20 of my favorite currently most-played songs and made sure I checked "Normalize songs volume" in Nero Express. Went to the car and played the CD. I made sure to include some songs that used to give me burn if too loud. Surprisingly was my reaction of how everything sounded WAAAY cleaner and better!. I think normalization did a great job here (also considering the fact of a music CD instead of Aux-in from iPod with regular 3.5mm audio connector). There was no "rocky" bass-feeling and notes sounded way more accurate, punchy and detailed. Really bassy songs played great. I also made sure to keep my gain at or below 1/2 of the bass remote (usually with iPod even 1/2 gives me burning smell). At this point, I think it will be better if I play it safe and just burn CDs. I will also lower my gain a notch more so I have more control on the bass. Any opinion on this?

Ok I understand now. So I did a good choice with the 2000D. Regarding the sub, when you hear the sub playing kinda "rocky" (like ugly bass up-down-up-down) with non-rap songs, those are signs of bass taking over mids and highs, low pass filter too high or stress? (no burn smell here). And yeah, would like to have a real experienced person to tell me whats that stress point I should go above. Will keep testing and see how things go, but really appreciate your help.

Yeah thats what I thought I should do, lower my gain a notch. But its really annoying it all depends on each of the songs' volume after all doesnt it?
