4 12'' or 1 18'' which will be louder

HAHA, I take it you watched my 18" Fi BTL "Building Flex" video //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
When I made that vid I only had 2000rms on it. I upgraded my Alt with a 260amp irragi and did another run of 1/0 gauge then installed a couple Optima G31 battery's to feed a Rockford T30001.bd that was giving the BTL around the same power that you have. You should of seen how much louder that aluminum roof was vibrating when I went back to the same spot I made the original video. It actually hurt to be in the car.

My box was 37" wide x 27" Deep x 19" Tall, about 6.7 or so cuft.

The "L" port was 5.75" wide x 17.5" tall giving me 100sq.in. of port.

The port went back 21" and the 2nd piece of the "L" port was 6 long".

This tuned the box to about 32hz.

I did a double baffel with thick support dowls going from top to bottom, with this setup it will get VERY LOUD...

what did you hit on the TL

 
Not sure exactly, I brought it to Edge Audio and Scott was there with his 2002 F-250 that hit 180.3dB, he said it felt like 146-148 db when he heard it. I know that doesn't tell you much, but thats all I've got. He did say he was very impressed with it though //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

WOW, im suprised you arent in the 150's. i mean i know 146 is decent, but i thought for sure you'd be in the 150's. who knows that dude might be wrong...

150's on music is insane. much different than a 150 db burp //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

 
i hate type rs anyways .. the surrounds have always seperated from the cones.. and ur amp isnt half ohm stable.. so id like to see you wire it down to that so i can c how long your amp lasts.. and the type rs handling 1000 watts? lol.. id like to see that too.. b sure to video tape it so i can watch it on youtube..
