Recommended box size and tuning for a single fi btl 12 running off a crescendo 3kwp at 1 ohm for a 03 crown victoria.

Goals, electrical background, your personal background, ex: building boxes knowing basics?

Need more info, glad you told us your vehicle but we dont know what the dimensions of your trunk are.

Here is a page dedicated for the BTL sizes 12-18 enclosure info

(Ported obviously) Enclosure tuned at 32hz be great,you will love your BTL, it will shake the crap out your car. Buy some sound deadener to deaden your trunk. I hear this stuff is great, the price is right too. It wasn't out of stock the other day but now is since it was onsale.25 sq. feet for $59.84 shipped, should be in stock in 2 weeks.

Look at SDS.

Great stuff.

Mine is in a 2.1 ft3 box tuned at 32 Hz, with a slot port firing through the side of the cargo area.

I love it, even on "only" 1500w.

Thanks guys not sure the dimensions but the trunks are huge on these cars though.
