    it should power one the speakers fine for now....they are pretty efficient

    4 cubes tuned to 30-35 Hz will do perfectly.

    I had one ehqs 12 in a 1 cu ft box tuned to 30Hz..yeah it was a box I built with scrap wood for a couple 6.5 inch subs...just glued on another baffle and cut a 11 inch hole for the sub...it actually sounded decent off 300 watts. But that was severely choking the sub

    Im not sure if fixing a head units speaker outputs are worth it...unless its brand new than it is under warranty...are the outputs full range??

    Do you have an extra small amp laying around to power the speakers??

    ok i bought the wood and my box is gonna end up being 4.07292cu feet i want to tune it to 35hz should i use 1 or 2 4 inch ports that are 4 inches long firing to each side
     
  17. jonnyv713

    jonnyv713 The Young Gun of CAT

    or should i tune it to 30 hz and be about 6 inches long each

    use two 4 inch round ports each about 12 inches long

    that would give you tuning around 33-34Hz which should be good

    i just ran the box through bassbox pro and the numbers i come up with is different than anzboi. here they are: to tune at 30hz 2-4" ports 48" long, 35hz 2-4" @ 34" long, and 38hz 2-4" 28" long. 30hz 1-4" port 22.5" long, 35hz 1-4" port 15.5" long and 38hz 1-4" port 12.5" long. All with a box net of 4.0 cf. Can someone check me to see if i made a mistake?

    yup those are wrong...I'm not sure why your numbers are off

    with a 4 cu ft box and two 4 inch round ports 48 inches long tuning would be 18Hz
