OrionStang Posted August 15, 2012 Report Share Posted August 15, 2012 With a ported box? Not accurate. Quote SMD Super Seller My Feedback Thread Link to comment Share on other sites More sharing options...
OrionStang Posted August 15, 2012 Report Share Posted August 15, 2012 Sealed box, play a sweep or series of tones, tune 2-3 Hz under that peak. As far as port area, that's probably something you will need to experiment with. Quote SMD Super Seller My Feedback Thread Link to comment Share on other sites More sharing options...
IH8PunkRok Posted August 15, 2012 Report Share Posted August 15, 2012 so 3k for a single 18 make some test boxes. one with sub and port facing the same direction and one with sub forward port side this will allow you to test every sub port combo except sub forward port back (usually not good unless in a hatch, crx) once you find which orientation the vehicle prefers start building boxes. i like to start big and shrink the box until you stop gaining. burp boxes are trial and error. so start trying Quote -Matt2005 Dodge Magnum RTJVC KD-AVX1 2 PPI S580.2 Obsidian Audio ST1 Horn Tweeters PRV 8MB450s Audio Legion 3500.1D 2 RE MT 18s 360 ah LiFePO4 BatterySHCA 2/0 155.2 @ 29 hzKicker CVR 15's buildDD 3512e buildMini T-Line Build(6) 8s BuildNightshade 15s Wall BuildMagnum AB XFL 12s BuildNewest Magnum Build Link to comment Share on other sites More sharing options...

fecupe2001 Posted August 16, 2012 Report Share Posted August 16, 2012 42 hz? seems way too low if you ask me, anyways, try to get some more power and definitely wiring the amplifier low as hell, i would do something like 4.5 cubic feet and 3 6" aeros facing side with the port facing up, that would be a good starting point...
