[QUOTE="froggy69, post: 5813302, member: 609280"] i'm wanting to build another box(s) for 4 memphis audio svc mclass 10's.i'm considering doing a ported box for the new build either subs up-ports up or maybe ports back.it's going in an 05 trailblazer. the subs will be wired for a 1ohm load and will be powered by a massive p1500.1. the specs memphis gives for 2 subs in a box with the optimum size being 2.8cuft tuned to 34hz with a port size of 10.5 tall x 2 wide x 19 long. i went and used the re ported box calculator. i came up with a box that is 23w x 16h x 18d.with a port height of 14.75,width of 2,length of 15.375.box volume before subs installed of 2.78 cuft. tuned to 34.887 hz.using 5/8 mdf.i will build 2 boxes to accomidate all 4 subs and was planning on turning them so the ports will be up and in the center. i know this box is just a little smaller than the optimum size recomended for the subs.i don't want to take up the entire back of my vehicle(kids and baseball equip) but was wondering what kind of sq and sp i could expect from this box or are my dimensions off?the area i have to work with is 46x18x16(gonna mount the amps on the 16 side of the box facing back.i have never done a ported box bofore and just want to make sure i can get the best sq possible and it not be a 1 note box.also don't want the spousal unit to give me the third degree if it turns out bad either.what's in there now(sealed)does the job just fine,but was built for different subs(little small). i like listening to just about any type of music. thanks in advance and sorry for the long post for my 1st post [/QUOTE]
