Flipped the subwoofers and its much clearer... However I now notice the insane amount of distortion I had on them D: I'm surprised the poor guys haven't blown.
Anyone know how to tune an amp properly?
Did the install on the new TB today & noticed something very peculiar. In the neck of the intake manifold there is a pipe sticking out. I'm pretty sure there should be a vacuum line or something connected to it. Otherwise it's a massive vacuum leak right behind the TB.
I want pics too

Just behind the throttle body. A bit to the left of the silver metal line. (I'm horrible with descriptions)
