DB Question

[Max4hdmatt 10+ year member]

i know this might not be a too realistic question. im just looking for an estimate.

how many decibels do you think i will hit with 2 15" L7's in a bow with 8.8 cu ft after port and woofer displacement with 111 sq of port tuned to 35hz. double baffle and about 1000 watts to each sub? im not sure what amp im getting yet. im just curious.

Thanks Matt

It would be much better if you just got it metered. No one will be able to tell you what you are going to hit, too install/vehicle dependent

L7's get loud, i'd say you might be able to get a 150 with those and that power but that would requre a bit of work, So I'll be conservative and say 145-147 if done right

by the way its going in a 96 dodge dakota ext cab. the back seat is coming out.

i figured it wouldnt be to much of an answerable question but i was just curious.

If you can't break 145 anywhere in the car then you have a problem.

Running 2kw, I assume daily, you're going to need that alt/battery sooner than you think. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

It also depends on where that 150 in the car is Some places easier than others.
