Hows this sound.

3 cubes of airspace
tuned to 30 hz.
Has a 3" wide port with just shy of 41 sq. inches of port area.

Externally, its 32 wide X 15" high and 18.75" deep.

This will house 2 x pioneer premier subs. How do you think it will sound please ?

Should pound

Actually, I think its the 3001 spl's

Nearly finished it now, just a few little things left to do. I didnt bother sanding the box down or anything inside, its a touch rough on the inside, nothing even major. Would it be best if I rubbed the inside down or am I really going to notice the difference if its left or not ?

Ordered my pionner premier subs so should be with me this week

My subwoofers arrived today and f**k me are they heavy. No need for coilovers anymore once I drop this mama in.

All I need now is some box carpet to complete.

Wish now I done a dbl baffle thingy on the front but ill sort it out nicely when its in the boot so it looks all flush.

I have now finished they have been installed. running these of a hifonics bxi 1606 and they pound. they drop really low, i mean real low. I have my amp gain turned up a near to half, does that seem right. No bass boost or phase turned on.
