P4killer_ Posted August 16, 2012 Author Report Share Posted August 16, 2012 Yea i got some in the corner there but you cant see it... I was gonna do that around the box when i finalize placement after testing.. but anywhere else specifically???

P4killer_ Posted August 18, 2012 Author Report Share Posted August 18, 2012 Ok Sooo Ive spent every day this week working on this project and Ive got nothing but inconclusive results.. Hopefully someone can help me sort through this. First the specs: SPL Box 2.8 net 6" aero port Firing forward in the tunnel as shown. Testing Procedures: The box was tested at different depths in the tunnel every two inches. Car off, external head unit Batts charged to 14.5v, allowed to rest at 13.0v Burp, record score Charge, rest move box 2" forward repeat.. blah blah blah. Loudest at the furthest position back.. So we burp: 143.7 @50hz reset 144.8 @51hz!!! like who gains a full db from 1 hz? we try to back that up and re burp that score = 144.4 reset 143.3 @52hz.. where did that full db go... reset try one more click on the volume.. 143.3 @51hz.. WHAT HAPPENED TO THAT DB??????? needless to say we tried to eliminate variables Changed the h/u.. similar results 143.3 ish The amp clamps the same.. 1967w @ 1.4x Ohms Dropping from 14.3 to 12.0 car on.. consistently clamping a shade less dropping to 11.7x v with the car off.. i dont remember those exact numbers.. Sub nominal imp @ .5 all coils check out etc The car is the same.. Port is the same.. Where did it go? So ignoring that problem that neither of us can explain.. we began shortening the port.. current tuning was at 41hz peaking at 51hz So by shortening the port and tuning closer to what it peaks at you should gain some.. I dont have the notes in front of me but needless to say we gain a tenth, shortened, gained another tenth All said and done with tuning @ ~50hz burps a 144.8.. So great we got back to where we were.. but does that mean it could be a 145.8 once we figure out where that db went? Either way the trunk is just about sealed as best as it could possibly be with out taping the box down after we finish testing and its not even close to the 146.3 they I did with the other box in the back of the trunk.. Now the whole point of sealing is to gain, which I havent in soooo many tries.. not even a tenth of gain and sooo much work went into this.. We thought maybe its the TL, on monday I might go and use my friends TL and use them side by side and see if mine is off, but why would it be,,? I mean wtf is going on.. anyway pictures: Quote Setup: 2010 Hyundai Elantra Factory Unit via 4 chan NVX LOC Excessive Amperage "H/O" Alt Xs D3400/ Xs XP3000 Big 3. 2 Runs of +, 2 Runs of - DD M3b and 2 12" AQ HDC4s Link to comment Share on other sites More sharing options...

P4killer_ Posted August 18, 2012 Author Report Share Posted August 18, 2012 and btw there is a shit ton of foam on the top the back between the tunnel and deck..sides are all foamed an sealed.. foam is like expanding through every nook and kranny possible.. so leaking is not likely at least to a point, but it should be almost perfect Quote Setup: 2010 Hyundai Elantra Factory Unit via 4 chan NVX LOC Excessive Amperage "H/O" Alt Xs D3400/ Xs XP3000 Big 3. 2 Runs of +, 2 Runs of - DD M3b and 2 12" AQ HDC4s Link to comment Share on other sites More sharing options...
OrionStang Posted August 18, 2012 Report Share Posted August 18, 2012 Weird results. Thats how this game goes though. Most intriguing is the lack of a gain from sealing it off. Quote SMD Super Seller My Feedback Thread Link to comment Share on other sites More sharing options...

P4killer_ Posted August 18, 2012 Author Report Share Posted August 18, 2012 Weird results. Thats how this game goes though. Most intriguing is the lack of a gain from sealing it off. Yea, i mean realistically for most people spending ohh idk 30+ hours easy and $150 in materials and gaining a few tenths especially for people who compete like my friend its time and money well spent.. a few tenths here and there is the dif between winning and losing.. now mind you i wasnt expecting a 49 or anything but maybe a 47 woulda been nice.. instead I lose several db.. oh yea and weirder still: We burp idk like 144.4 at 51hz without a charge like we put a few burps on it at that point.. charge etc etc Same freq and vol = 144.2 at 51hz LIKE HOW DOES CHARGING LOSE DBs!!!!!! like what in the hell is going on.. Thats why we started questioning the TL now that I think of it..
