5-6 cubes ported would be good, preferably 6.

Go to kicker's website and see what they recommend. I would go with 5 cubes or so. You have plenty of power so a really big enclosure isn't necessary.

4.5 is the biggest I'd go. The bigger you go the more output you lose.

I have one in 4 cubes tuned to 38hz. It beats hard in the tacoma. Dash moves up and down about 1/2 inch on some screwed and chopped songs. Steering wheel shakes. Doesn't sound that bad on rock songs. I had one in 6 cubes tuned to 32hz. It beat much harder in a ford explorer.

Ok well the re calculator said the volume is 5 i assume thats total before woofer how much do i loose with wood and sub and what not , hard deciding how big to make it as everyone says something different, and should the port be 3.5 4 4.5 how wide what is the difference is sound ? and the l port wall how long should it be and does that affect sound much right now it's at 10" and tuned to 28 i wonder if thats to low

im gettin ready to start my box next week so i got in touch with a kicker rep and he said to tune it at 32 to 34hz. your box looks almost identical to mine, 28 width,18height,22depth,4x10 port 33.56hz. i may make my box a little taller and wider like yours hopefully someone will chime in and give us some info

A really large box is going to play flatter and be more musical, but you'll sacrifice output and power handling. However, you'll gain efficiency.

There's really no point in tuning at 28 unless you listen to nothing but songs that peak in the 30's.

ok but now my main ? is how wide to make the port 3,3.5 4 4.5? my last box was 3.5 and how long to make the port wall length (the l bend of it )is 10" good shorter longer? and how much affect does tboth have especially on tuning and sound
