Hi guys

I bought 2 x DD 515 ,and now i need help.

My car is Ford Mondeo Mk3 (stationwagon)

HEIGHT 41,5cm

WIDTH 114CM

DEPTH 80CM

Amp for subs = Audio System Twister F2-500mk3 (about 1,2 - 1,3KW at 2ohm)

So, i was thinking about 35-37hz. Box will only to listen

Here is a suggestion, power: to subs rated, amp subsonic filter to 28Hz, minimum port clearance 17 cm, figure is just an assembly guide:

But it is possible to slightly raise my tuning ?

From 35hz to 37-38hz ?

what should I change,in this case ?

Shorten port ? How much cm.?

[Joe X]

Changed to 37Hz.

i am in doubt :/

This box has many Volume ,and these subs are "entry series"

each takes about 3-4liter. So the two togethe 8liter MAX

im afraid ,that was too big box for this subs :/

really ,I do not know :/

should be reduced liters ?

or will this plan right,and it is this ?
