As the post says .. im looking for the Res Freq of one of these Vans..

I know how to find Res Frequency, but im strapped on time.. I got 3 hours to build a box Saturday / run a welding Cable and rca's for a show on Sunday..

Also the 3 pass seat in the middle or should i take it out?

1) Subs up Port Back?
2) Sub up Port Forward?
3) Sub and port back?
4) Sub and Port Forward?

 

what class?

for street class u have to keep the 1st row of back seats in the van

 

Subs Up and Ports back for street will get you started, Have it Peak at 52-60hz in street; 1.75cubes per sub, and 57-62 for SS1-2, No-Wall, with a huge box up front, 400sq" of port, and 20 cubes.
Peace

 

Its just for the local show here on sunday at redball radio.. From my understanding its woofer inches and power.. +/- 500.. Last year i was classed using a true street B setup with guys running 2 Batts / 4 amps etc etc..

i mught just throw that explorer box in there and run the 200.1 on it.

 

Thanks Lee.. i think im gonna run the explorer box.. (Yuli seen pics of this one) 7 cubes / 4 15" facing up and (38.5x5) 200sq" port facing back. its gonna peak about 52hz as if i read winisd correctly i got it at about 43hz tunning.
