aV8ter Posted March 9, 2010 Report Share Posted March 9, 2010 Damn that sucks. Shit looks good mad. You'll like how efficient that box is. There is a guy with a jeep, same style box(i have a feeling you know who i am talking about), 2 18 bls, 1 aq2200 at 1/2ohm, doing 150s all day, smashing the lows.

Yep, that's where I got my motivation. With double the power I think it should do well. 2000 Blazer 4dr -24" Boss 330s -Lowered 2/3 -5000k Hids w Projector Retro -Candy tails -LED interior lighting -20% tint 35% windshield -Alpine 9886 HU -RF P1462 Dash -RF P1652 Front -RF P1652 Rear -Two 18" Fi BTLs -MB Quart Onyx 4.80 -Two Audioque AQ2200Ds -Xs Powerr D5100, 2 Powersafe G31s -Knukoncepts 1/0 wire -Mechman 270 Alt w Boost Module -10.4 Net @ 28hz 140sq.inch of port My Youtube Channel!!

aV8ter Posted March 10, 2010 Report Share Posted March 10, 2010 My math shows you would have to have just about 30 inches of port length to achieve 31hz. How did you get 31hz? Link to comment Share on other sites More sharing options...
Carnag3 Posted March 10, 2010 Author Report Share Posted March 10, 2010 My math shows you would have to have just about 30 inches of port length to achieve 31hz. How did you get 31hz? Check your math. You must be calculating with my final airspace after sub and port displacement, which would give you a different port length. Ports are 2.18cuft combined, leaving you with 14.04 before ports. Hope that helps. 2000 Blazer 4dr -24" Boss 330s -Lowered 2/3 -5000k Hids w Projector Retro -Candy tails -LED interior lighting -20% tint 35% windshield -Alpine 9886 HU -RF P1462 Dash -RF P1652 Front -RF P1652 Rear -Two 18" Fi BTLs -MB Quart Onyx 4.80 -Two Audioque AQ2200Ds -Xs Powerr D5100, 2 Powersafe G31s -Knukoncepts 1/0 wire -Mechman 270 Alt w Boost Module -10.4 Net @ 28hz 140sq.inch of port My Youtube Channel!!

Hope that helps. Calcs are done after all displacements. That's why designing an aeroported box gets kinda tedious after awhile. Link to comment Share on other sites More sharing options...
Carnag3 Posted March 11, 2010 Author Report Share Posted March 11, 2010 Calcs are done after all displacements. That's why designing an aeroported box gets kinda tedious after awhile. I used 3 different calculators and all gave the same tuning results. 2000 Blazer 4dr -24" Boss 330s -Lowered 2/3 -5000k Hids w Projector Retro -Candy tails -LED interior lighting -20% tint 35% windshield -Alpine 9886 HU -RF P1462 Dash -RF P1652 Front -RF P1652 Rear -Two 18" Fi BTLs -MB Quart Onyx 4.80 -Two Audioque AQ2200Ds -Xs Powerr D5100, 2 Powersafe G31s -Knukoncepts 1/0 wire -Mechman 270 Alt w Boost Module -10.4 Net @ 28hz 140sq.inch of port My Youtube Channel!!

01 S-10 Posted March 11, 2010 Report Share Posted March 11, 2010 Your not tuned to 31hz. Go to precision port's calcuator and you will see you need 30 inches of port to get 31hz with a box that is 11.85 cu.ft. You calculate using net volume not gross volume. How long are your ports? I think you may be closer to 40hz. TDH FTW !!! Link to comment Share on other sites More sharing options...

It is a good box design and I still have no doubt that it will be awesome to listen to. Link to comment Share on other sites More sharing options...
Carnag3 Posted March 12, 2010 Author Report Share Posted March 12, 2010 Ports are 24" long each. How can you both say my tuning is wrong when you don't even have the port lengths Looks as if I'm close to 1hz off. 2000 Blazer 4dr -24" Boss 330s -Lowered 2/3 -5000k Hids w Projector Retro -Candy tails -LED interior lighting -20% tint 35% windshield -Alpine 9886 HU -RF P1462 Dash -RF P1652 Front -RF P1652 Rear -Two 18" Fi BTLs -MB Quart Onyx 4.80 -Two Audioque AQ2200Ds -Xs Powerr D5100, 2 Powersafe G31s -Knukoncepts 1/0 wire -Mechman 270 Alt w Boost Module -10.4 Net @ 28hz 140sq.inch of port My Youtube Channel!!
