[QUOTE="bigred78797, post: 230574, member: 545232"] Yeah WinISD PRO. Just a few things to help you out. #1. Keep the Air Velocities down. Try and stay below 40 m/s, don't scratch the plan if you get 45 m/s. Now with some Mega subs dont be afraid to sacrifice some air speed. I know with my subs the plot said my air speed gets up to 65 m/s but those are some heavy hitting subs and i don't have any port noise (above 15hz or so.) #2. Keep the Driver Excursion (Xmax) down. Try to stay at least a couple of millimeters away from your Xmax. Usually the Factory specs give you the Xmax( MAXIMUM excursion ) but damage usually occur a before reaching the Xmax. This is VERY IMPORTANT... THIS IS NON NEGOTIABLE THERE IS NO FORGIVENESS WITH THIS RULE... YOUR SPEAKERS WILL FAIL IF YOU DO NOT DO THIS PART RIGHT. NOT FOLLWING THIS RULE IS THE FASTEST WAY TO BE OUT OF $500 worth of speakers. Trust me i did that, thought that just because the Xmax was 32mm the speakers were undestroyable at 300w... Was REALLY WRONG. #3. Take measurement of the car FIRST and determine how much room your willing to sacrifice. Start your volume there and tinker with the ports and lessing the volumes to perfection. #4. Keep the SPL LEVELS HIGH [IMG]//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif[/IMG]. And have fun doing it. [/QUOTE]
