I made this series of test tones and sine sweeps to help a member set up his system. I figured since I went to the trouble of packaging these and uploading them, I would share these with everyone. These will work great for setting up your system, adjusting crossover points, setting EQs, and determining how flat the system really is (using the final series of sweeps)... oh yeah, and just for showing off, if you so choose . All are unclipped 0db signals. I have enclosed the track list in a wordpad file, and I will include it here for you to determine if this set is for you. I have also added a set of pink noise tracks, as requested by another member. It will be the second download link. I also will add a tutorial with images below to help you extract and unpack the .rar files to a standard .wav folder and files. This is saved on rapidshare, uncompressed in .wav format. It is under 100mb so you do not need a premium account to download it. DO NOT COMPRESS THIS FILE TO AN MP3!!! You may convert this to any lossless format, including, but not limited to .flac, .ape, and .wmp. Compressing these tones will result in incorrect settings, as lossy formats will not maintain all the required information. If you are not sure what formats can and can't be used, please ask here or PM me directly. I take no responsibility for you misusing these tones and damaging your speaker system. If you have any questions, ask. If you have any doubts, let a professional perform your system set up and tuning. These tones may cause catastrophic speaker failure if misused, and they can cause permanent hearing loss.

Just a quick video I took with my Blackberry today. I can't find the cord for my JVC Camcorder that hooks it to the computer. So specs for this video are as follows: 2- 12" SSD subs Stock specs 4 cube box tuned to 30hz Subsonic set at 27 hz volume 15 ( gain set at volume 30) Subwoofer set at -7 at the head-unit ( gain setup with sub at 0 on the head-unit ) 1600 watt Soundstream Amp I was amazed at how much flex it created at such a low volume. Once I find that cord I'll upload a better video that shows just about all the flex like the windows, roof, etc... Really happy with these subs! Sound awesome even at full tilt playing music! And yes, I did drop my phone... cause I'm a tool. lol Still need to tuck the wires just haven't had time and I really wanted to hear it. Will be done this week though.

I would just get rough measurements. Your door is not completely sealed, it's more of a leaky sealed box, so your physical Vb is going to be different than the effective Vb. Without knowing the loss factor (i.e. the amount of the leaks) you aren't going to get it 100% accurate anyways. IIRC you basically have a pod built onto the door? You might get a rough measurement of that as well.....one thing you may consider doing, depending on what mids you are looking at, is to seal the pod. If you knew the volume you could calculate how that would affect the Qtc and Fc. You might be better off using a lower Qts lower Fs driver in a sealed enclosure to bump the Qtc up to the .6-.7 range since a high Q driver is going to be harder to find, and in your situation I would probably go for a higher Q alignment to try to get some more response in the 50-100hz range.

Guys I run the AX line in my second car. I have the 600de pushing an IDMAX12D2 and it is very strong. Great amp with small footprint. Don't count it out because, it doesn't kick out 1.21 Gigawatts. I have also run the AXTU4360 for highs and midbass. I believe that the AXTU600C is a 2 channel amp though-- an excellent choice for midbass duty. I did feel like the highs were a little harsh on these amps though. When I used the AXTU4360 for midbass duty I was really happy. The best price I could find on the TU600 was $599, so this is a steal.

Welcome .... Browse the SSA store for some great choices on subwoofers.

Today's computer systems are designed to eliminate spark knock/pinging/pre-ignition. Not only is it a detriment to the vehicle's motor life, but it also creates excessive HC emissions as well as spikes in NOx, and it can shorten catalytic converter life. The ECU system uses a knock sensor which quickly detects pinging and will retard the timing, and/or in some cases will open the EGR more then typically mapped for the situation. In all these cases there will be a reduction in power, and a decrease in fuel economy. What I have found is that with today's cars the cost/mile ratio works out to be about the same when you select different grades of gasoline. What I mean is, if you put $20 of low octane gas in the car and typically get 200 miles on it, you will find that you get 200 miles on $20 of high octane fuel as well. So there is really no savings by putting in low octane gas. As a disclaimer, I am a 30 year technician with my ASE and AC Delco master certifications.

When you click on the rar file you will see this (without the red circle) Click the extract button (circled) and you will see this Just click OK (circled). It will create the folder for you in the same location as the downloaded file, and extract all the files in the folder, leaving you with this open it and you will see this

Quick video via my Black Berry playing a bass song. Camera picks up flex for crap. New video coming tomorrow after I change my JVC up.

Qtc = Qts * [ ( Vas / Vb ) + 1 ]^.5

Working in the rain....gotta meet them deadlines

Thanks everyone, this setup was worth every bit of sweat (and blood!). These subs sound so great they still amaze me. On the 23 hr drive back home, i listened to damn near every song on my iPod, threw everything at them, country, rock, metal, rap, you name it and they sounded great on em all!

Bracket is finished! There will be slight changes to the spacers on the alts so they are more even, but I'm going to the machine shop tomorrow. Pulleys located: The line represents a 90 degree bend in the metal: Belt wrap?

I found a few pics I took while test fitting. You can see where pulleys need to be. I was at least a good 6 inches short, and this belt is 9 inches difference. Also looking at the pics, it's funny how when you wire for 4 alts and don't have them in how bad wiring looks. I have my extra + runs on the alternator post, and grounds on the battery terminal. There will be one run of + and ground per alternator. They will also all be looped together. There is a fold in the bracket that I couldn't make with 1/4" mdf, but in metal it will add strength and allow me to run any wiring I need under the alts and bracket instead of over.
