Guest Posted February 19, 2009 Report Share Posted February 19, 2009 if im right, you only have 10-13sqin of port per cuft, which is kind of low. every car environment is different, acoustics are a bitch Quote Link to comment Share on other sites More sharing options...
Team_DC-Derrick Posted February 19, 2009 Report Share Posted February 19, 2009 well your tuned low so you wont hit nearly as high as you should say tuning to 38-42 hz and in a hatchback, which has been said a few times in another one of your posts, subs up port up is louder, to a few people.... including my self. 147.6 is a good score tuned at 32 hz but if you switched it to subs up port up, you would prob hit higher Quote The DC Integra 3 18s to 6 15 build log Team_DC-Derrick's Youtube Team DC Audio where theres a will theres a wall....... I just realized Steve has reach Voldemort status, over on JP's site he is the one who will not be named....."We dont speak his name over here, fearing it will destroy us" LOL not even in hush tones Link to comment Share on other sites More sharing options...

Cr@sh Posted February 20, 2009 Report Share Posted February 20, 2009 If your truely going for SPL and don't care about sound quailty then I rebuild your port and tune for around 45 or 50hz, your peak note will a little higher whatever you tune your box at. I seen a two db increase from tuning of 35hz to 58hz, but I am building a removable port so I can have both sql and spl. Quote My old install at cardomain, never finished!
