Hi guys, yesterday i install 4x mtx thunder 7500 12" in my corolla i have them in sealbox with 0.81 cubic feet for each subs, it sound very hard, but i lost the low freguency they told me that's because that the box is to small for them, they needed 1.25 cubic feet to work fine, but i cannot make a box that big, i can make one that is 1 cubic feet, so my question is should it be a hearing difference if i gave my 4x 7512-04 subs 1cubic feet per subs, that what i have right now(0.81 cubic feet) for them? thus should it be a huge difference between 0.81 and 1 cubic feet? and is it normal that the cones of the woofers get warm? anyways, thanks guys.
if u put acousta stuff in your box, it will make the area of the box go up 15%.so, get the 4 cube box and if its not good enough, put the acousta stuff in there. or, do the opposite. get the acousta stuff first
