Guess a slight update. No major tangible progress but a few things have happened.
First off, Mags should be at my doorstep this coming Wednesday (according to UPS tracking numbers so its totally legit) //content.invisioncic.com/y282845/emoticons/woot.gif.aaa6090e619a97b6090d16dd863c5a69.gif
Also I had some good tuning done by someone who actually knows what they are doing lol. He spent 2 hours listening and tuning and teaching, was VERY useful and hopefully it will help me on the path to understanding what I am listening too and who knows MAYBE some day competing in some IASCA or similar comps.
With a good boost around 63hz the SR6500's really come to life //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif Even in the undeadened doors there is a great deal of midbass. The sound is leaps and bounds over what I had before, I fiddled with time alignment but never really got into equilizing the whole system. This is also where we found a MAJOR downside to the 9887, the 5 band PEQ is pretty stupidly limited. Either way I am loving the components even more so now and can't wait to get the system rouneded out with the subs and at least then have a "complete" system and can focus on the install and then thinking about upgrading/adding gear.
Wouldn't be a good update if I didn't have any pictures. So here is what I got.
Got the Center console pulled from the truck to gut it and take measurements and see what I really have to work with.
Currently, I am looking at simply removing the lower cushion and just replacing it with a sub box and maintaining the upper console portion. Would be sweet to add a sub and maintain full use of this as a middle seat but I don't really see that happening.
Great part of trucks, Built in workbench //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
Back together minus the lower cushion.
So not looking like I have much room to keep this simple. The rails bolt to the lower metal pan as well as the arms to the upper console, which isn't what I was hoping. To ditch the lower pan and make a nice downfiring box I will either need to cut the pan, or attach the rails to the box and the upper console to the box and replace the pan. OR build the box, attach the console to the box and then figure out a way to bolt the entire assembly to the floor of the truck.
From what I can tell I have about 2.15ft^3 for the entire enclosure, not interior volume but the volume the enclosure can occupy. I really want to do a downfiring box since it will allow the sub to load off the floor, plus I want to direct it towards the front of the truck. I plan on building at the very least 3 boxes. One will hold both subs without much regard to overall size of the box but just to get both subs in the truck. Another will be more of a stealth minimal build for a single sub and see if I can maybe get something that will completely allow use of the center seat. The third is something I stumbled on a little while ago and still learning about.
This is a quick sketch I did for the 3rd design.
For most this is probably not a new concept, but for me it is. I read about 4 pages of discussion on why this style box was used in a Dodge ram for a pair of JBL WGTi 10's. These subs also required 1ft^3 as the mags do. This design is a planar loading isobaric box (at least as I read it.) This will allow me to cut in half the required sealed volume for the single sub and the second sub will essentially be free air. This allows for the output to be directed towards the front of the truck as well as be downfiring and make for a fairly cool looking build with some plexi and such.
This also cuts the output to be equivalent to a single woofer though. The secon sub is wired in revers polarity of the sealed sub so that they will work in unison through the upper coupling chamber. The second sub will have sort of a shroud around it to direct the output towards the floor and then out towards the dash.
Oh well, those are my thoughts and updates. I would love to hear more ideas/thoughts/criticism on the box design and what not. I am thinking of sealing the output from the rear and sides of the console and forcing all output to head towards the front instead of just general downfiring in all directions. These are all thoughts and stuff I will have to experiment with or hopefully maybe get some direction from people who have more knowledge than me.
