naw you will be surprised, just make sure the port is huge..or it will not have the affect you want, needs to push a ton of air into the front of the car.

 

How huge are you talkin?.... like how many sq. inches of port face per ft3 of net box space? I know DD recommends like 14-16 or something, but is that enough?

 

my port for dual 12's is..like 10 inches by 8 inches or so..i can't remember exact dimmensions but it is large.

 

I have a 6 cubic foot box, with two tens and and a 10 x 10.5 square port, in a trunk, also facing forward.


Im hitting 147.9

 

o ya my port is pretty big around 10x10 or so havent really mesured i know that its done the best that it can be done to fit my trunk the box was done by someone who knows what hes doing hes a world champion so i dunno i guess theres no way to really know untill i get it tested out so i'll be waiting to do that soon

Hey Snipes I`m from Peterborough also, I have a mic we can run a spl test on your car if you want? who built your box? I have been building car audio cars here for quite some time (have my own business)

learn something about SPL before you give stupid answers to others! you have absolutely no idea what you are talking about!


tuned to 40 Hz its gonna be hard to be loud for SPL... but will be rally loud for listening... my guess is that your doors flex like crazy when you play muzic that hits low

 

ya well im not really going to be going into comps with it and stuff but ya it's defently loud for listening to music and stuff just wanted to kind of know what the acctuly DB's it puts out but well i might be able to find out now LoL

Well, I happen to drive a trunk car and use it for SPL, and this is excactly the results I got. Rear seat removed, I got 4.X less dB while firing sub and port front than I got while firing it toward the back or the side. Firing it front with trunk baffled was a full 2dB louder than any other position. This was using a very large rectangular port too. Switiching to a smaller, flared rectangular port gave another 2dB.

big box firing frontward with large port = 132dB
smaller box with smaller flared port firing frontward, with trunk scealed from the cabin = 143.5dB
