the subs require .64 cubes optimal for 27.38 tuned in a ported box according to my bro-in-law. but we are having some complications designing a box. we are looking at doing (2) 8" re's mounting depth is 4", with a Rockford Fosgate 800A2 amp. this needs to neatly fit under the rear extended cab seat. any suggestions? he does design some very hard hitting systems, i actually envy his system in his hummer, but this is just going to be my economy build.. nothing fancy. any help with some measurements for the box?

Anyway to get measurements to see how much room you are wrking with? 2 8's under your rear seats should be pretty easy to accomplish.

i could see if i can get someone to do the measurements, but I am like over 7,000 miles away from my truck.

i should have on estimates only, 18in x 34in x 8in which calculates out to over 2 cubes under that seat
