STEvil Posted May 21, 2012 Report Share Posted May 21, 2012 sub next to internal port mouth = loading issue.

Any time you have have a power wire next to your frame put some rubber hosing (or cut up an innertube) around it. The wire is bound to wiggle (due to driving or flex) and the casing will eventually wear through. Hammerdown... 1% no links to outside websites, business related FB/YT pages allowed.

412 CVX Posted May 22, 2012 Report Share Posted May 22, 2012 looks good. and 34 hz is a fine tuning. Quote Just say no to Ground Pounder Customs. My temp system build log More box buildssome cars do over 170db with one sub, so clearly my two 12"s can do that in my car, with my knowledge too! look out bitches! I'm with captain stupid.

Ridin Solo Posted May 23, 2012 Report Share Posted May 23, 2012 I have a related question... I'm running (2) 18" Aq HD3's powered by (2) Cresendo 2250's .. My current class is Super Street no wall and would like to stay in that class...Only way i can make box work and stay in the peramiters for my class is to Drastically round the top of my box .. I guess the best way to describe it is a letter B with the humps up..LoL .. already have everything designed and used torres calc to figure port size.. Will be porting out the front in the center between the humps , subs will also be on front on either side of port...My question is will the round tops of the box cause any problems? It's kinda like 2 base tubes connected with a common port...But don't know if the round top will cause air to swirl around in the box?

412 CVX Posted May 23, 2012 Report Share Posted May 23, 2012 The problem i forsee is trying to calculate the volume of that, and getting the port area and tuning you want after you find the volume Quote Just say no to Ground Pounder Customs.

Ridin Solo Posted May 23, 2012 Report Share Posted May 23, 2012 Calculating the volume was fairly easy....I designed the box on paint.net first (which allowed me to draw it to scale and gave me the total square inches).. Comes out to 968 square inches for the face of the box times 29 inches deep (internally) for a total of 16.245 ft3 before port... According to Torres calc port should be 18.5 inches by 10 inches and 18 inches long tunes at 34 HZ..Which gives me a net volume of 12.58 ft3 and 185 in2 of port area... just not sure how subs will react in a partially rounded box...
