Rear cab vents, Bass and Flapping

[DaKing]

I have some subs in my truck.

I have 2 rear vents molded in to the back of the cab. ( all trucks have these vents with rubber flaps)


The audio IN the truck sounds awesome. The audio in front sounds great.

However, if standing next to rear or side of truck, it sounds like crap. The issue is the Bass is forcing air out of the rear vents, causing the rubber flaps to vibrate. Sounds extremely bad, like blown subs.


How to stop the fapping ?

Wrong section, this is for 5th gens only.

Secondly - who cares what it sounds like outside?

Don't seal them!

Thanks, I own a few trucks. This one with the issue is a 4th gen... Still Wrong place though.
