Well... I'm not sure..

It kinda sounds more like a big pfshhhhhhhhht. Sounds more like a fart facing forward.

I'm going to have to listen to it more tomorrow, I only listened to it LOUD for about 30sec today haha.. I hate driving around town with it loud..

Well I switched it back. Sounded like **** porting into the cab, and was not as loud.

so the loudest was when you turned the box sideways and the sub and port both faced the driver side?

with this current setup the only way i can get it as loud as i'd like is to have the trunk open and the driver side door open. just seems hard to cruise down the road like that so im lookin for alternatives lol.

i can position my box 3-4 more inches from the trunk lid if need be. would the port be lacking air being this close or something? which would explain the trunk being open and it being louder?

alright, this gives me reason to get the amp off the box as well, i screwed that thing down with 8 screws and it still rattled like a *****. prob not good for it's internals anyway lol

you just need a new box.....

andwhat worked in my car may be different for other cars

Should have used two 6" ports instead but you get the idea
