  1. Thickness vs thickness plexiglass is stronger

    think about fishtanks, 250gallons of water 200lbs 8feet 2feet by 2 feet, think wood that was 3/4 (or a little less) it wouldnt be able to hold the water even it it was resin'ed to waterproof it...

    I thing it might effect sound couldn't tell ya, my 1" thick plexi side on my box is one of tne stronger points on my box, needed no bracing and its the biggest peice 24x 40.5

    where the wood top and bottom needed bracing and they are 18" x 40.5 now braced with a 2x4

  2. If I were to rebuild I would build box with the sealed chamber

    hook it up then sweep the meter

    Then tune the box to that frequency, that's how some of the big boys do it

    Or u can just kinda pick a ratio and go for it!

    If I were you I would do 3 cubes sealed 9 ported after displacement. 175 inches of port to start and tune to 45hz

    Shrink the port if the subs unload after testing, just put 3/4 inch birch inside it shrink to 160ish test then maybe 150 ish prolly not 175 seems legit

    Im no genius.Many on there know way more than me

    You arnt running a huge power the the big box would help, but the small sealed chamber will bebefit when you actually decide to wire ur amp down or get more power :)

    I would reccomend you read the thread on caco called " why 4th orders arnt loud" hankmunch or something I don't remeber his exact name has a ton a great info

    Ray (dc98hoe) pointed me to that direction to read some of the best info I've ever gotten about 4th orders!

  3. What berto said is right tho^^^^

    U can always go bigger on ur ported area to increase the ratio, if u add power ull want a small sealed big ported ish

    Ideally you want to tune the ported section to the resonance of the sealed section so build that first then put the loading wall on last with the port tuned to that sealed resonance in the car :)
