THEAUDIOPHILE Posted September 25, 2014 Report Posted September 25, 2014 I'm new to this forum so pls forgive me if I sound like a tart. Well I'm building a box for an FI SP4 15" into the trunk of my 09 altima sedan. My max box specs are 26.5Wx28Lx15.5H 3/4 MDF. Now I have a MMATS HD4000.5 (4000 rms underrated) amp and the big 3 upgrades. I've used win isd before with little success and I've used various websites to calculate my port size but they give me different sizes. I'm looking to use as a daily and I want this sub to pound. I also have 6 beyma 8" midbasses and 4 monster beyma tweeters installed already. So i need a box that can really keep up. Now please keep in mind I listen alot of mainstream rap and house and deep house music so I'm assuming the box should be tuned to 34hz but I'm not sure. I'm also torn between front face or rear facing the box because my back seats do come down. THANKS IN ADVANCE. p.s cant paste link to sub specs but google fi sp4 15 and it should be the first link.

Smoove Posted September 25, 2014 Report Posted September 25, 2014 no prob. I am running in that range and it's the most recommended range I have seen for that sub on this site and many others. 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/
