  1. ^that ur amp cant get 1000hz because ur amp is cutting it off, starting at "250" as you stated u should always be setting the gain with headunit at 48. typically, it wont sound "loud" to you until volume 30+, that is normal because the bulk of rca voltage is created closer to 48 for your deck
  2. that would work but it makes no sense to hook up a set of rcas to test the pass thru when u can take the input rcas already ran thru the car and test that. gain can be anywhere if you are testing pass-thru. the term pass-thru means it goes thru nothing in the amp
  3. We also chose an RCA input connector for a few reasons: • It makes it pretty easy to measure the output of a headunit directly, if you choose to do so this insinuates that most people will check headunit rca clipping through the amplifier they are soon to set the gains on. this is advantageous because then you do not have to switch the probes. simply turn gain down to min and check headunit with track 1/2, then switch to desired db track and turn gain up.
  4. gain at min testing speaker terminal + is same as testing headunit rca so says the booklet, at least thats how i understood it
  5. the problem when i tried was 1) my knukonceptz are curved and dont even fit into the opening and 2) even stinger/db link/rf rcas did not work because it seems the ground shield doesnt go down far enough into the unit... only way we've gotten it to work is thru an amp, which doesnt matter, its the same end result lbox, a headunits amp that power speakers can clip before/after the rca's do... so that is not a sufficient
  6. ive never been able to get a signal from rca input on the top of the unit, i've always had to through the amp speaker terminals
  7. set HPF as high as possible for that test while doing 40hz, making sure that the rca going to the sub amp is not affected by that filter
  8. i miss hookups with songs like that wonder
  9. turn sub level to +15 and redo test. what tone did you use, -5/-10/-15?
  10. in the booklet the "SQ" setting is -5db for both 1000hz and 40hz -5db is the safest setting beside 0db on the cd provided and it is what I recommend/use to set my gains. -10db is what is recommended, but there are plenty of songs that are louder than that, so its a good compromise but is less safe than -5db. in my opinion, use -15db if u never listen to rap/heavy metal/dubstep. if available, you could use -10db and simply alter the sub level on the deck to get the desired effect, but thats for those who know their systems limits and know when to turn it down the closer the value of the tone to ZERO the louder it is, which means your gain will be set lowest to match

  12. to find 45s its just the area of a triangle X height, the displacement depends on how big your 45s are area of triangle = 1/2base X height volume of 45s = above X internal height of box multiply that number by the number of 45s you will install then divide by 1728 to get cuft displacement area of a circle is radius squared X 3.14 .5 X .5 X 3.14 = .785 .785 X 93.25 = 73.20125 73.20125 / 1728 = .042cuft of dowel displacement
  13. for a slot port, yes because its using an internal box wall as a port wall and the box wall extends beyond the physical port wall. 28 is the input for port length for this box using torress calc 14+8+.75(port wall thickness) = 22.75 physical port length the green box should say 30.25 for 6cuft@33hz
  14. port length is measured down the center .75 (front thickness) + 14" + 2.25"( distance to center before 90degree turn)+ 2.25" (distance to 2nd port wall)+ .75(port wall thickness) + 8" + 2.25" (end correction factor for slot port boxes which is half the ports width(4.5"/2=2.25"))= 30.25 effective port length ull want a brace from top to bottom that that goes on the left of the sub to brace bottom of box and top(baffle)
  15. lowers volume of all songs to the quietest track definitely turn it off/use usb or sd
  16. green tinted DOA 4door explorer i dont have the design on my computer anymore so this is rough guess, but ive got a pretty decent memory Double Baffled/Braced Well/Double Front/Back with thick Granite Paint/2+ 2- Bolt Terminals 45w X 21h X 35d 42 X 4.5 X 14d Port plug is 11 X 4.5 must be it, did he also buy brian's old mayhem box? to replace that one in the pic? but i wont really need the box depending on the use i wanna put the woofers in...planning on walling my mustang, or if my deal goes through ill have a 94 chevy blazer those squarish bodystyle so if do get that then ill take the box for funiz for the right price expect a pm from me tomrrow and ill update you on it no thats DOA Memphis with the black tahoe that bought brians old box. they go to school where i live. cool. im in no hurry, these subs are minty. if you pick up the subs box price will be lower. not trying to drive my satty with an extra 180lbs ontop of my system, lol.
  17. You've seen it before likely at radio doctor show. Team DOA Amin's box that i worked on/designed. we are in dekalb, 1hr away. might make a deal if you drive and take the box too
