apparently im not vent savvy so id appreciate some imput. i got a box about 2 ft wide 4 ft long by about 7 ft tall. its got a 400w air cooled hood with a 435 cfm valueline inline pulling air through the hood out the cab. theirs 2 passive 6'' intake holes. the exhaust is also 6''. ambient temp is 75, however the cab temp rises to 90 which is causing too much stress. any ideas on how temp can be reduced? id appreciate any help, thanks.
