hdorre Posted December 4, 2016 Report Posted December 4, 2016 Vent mach is essentially port velocity. 3 4 inch ports or 2 6 inchers would do you well. Id prefer the 2 6" ports though.

Why would you think the minimum for an 18 is ok ? 2 Team Fi 15's v1 2 DD M5's 970amps of Alt 6th order blowthroughThe truck Blowthrough build : http://www.stevemeadedesigns.com/board/topic/155555-smooves-1996-chevy-ext-cab-c1500-slow-build/The 350z build : http://www.stevemeadedesigns.com/board/topic/170694-smooves-2003-nissan-350z/ My FB page https://www.facebook.com/pages/Smooves-Car-Audio-and-performance/719746144805343 Team Fi Audio http://www.ficaraudio.com/

Tjwubs34 Posted December 4, 2016 Author Report Posted December 4, 2016 if you're gonna build outside recommendations and recommended specs then Have fun. not saying i will it was my fault i thought they reccomend 4-6 cubes its 3-5 so i got that straightened out. i will tune around 4.25-4.5 with a 4" port tuned to around 30 hz. i have never used FI audio like i said so i dont know what they like
Smoove Posted December 4, 2016 Report Posted December 4, 2016 4" and 6" aero are too small. You will need more to support port velocity. when using the VERY gereric port per cube rule. it's 9-12sqin of port per cube using an aero. Which is a 7" minimum4.24-4.50cu is great. 2 Team Fi 15's v1 2 DD M5's 970amps of Alt 6th order blowthroughThe truck Blowthrough build : http://www.stevemeadedesigns.com/board/topic/155555-smooves-1996-chevy-ext-cab-c1500-slow-build/The 350z build : http://www.stevemeadedesigns.com/board/topic/170694-smooves-2003-nissan-350z/ My FB page https://www.facebook.com/pages/Smooves-Car-Audio-and-performance/719746144805343 Team Fi Audio http://www.ficaraudio.com/

Broke_Audio_Addict Posted December 4, 2016 Report Posted December 4, 2016 If you're going to run sub up port back make sure you have enough space between the port and the hatch otherwise you'll suffocate the port. That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.
