Ram1989custom Posted May 2, 2012 Report Share Posted May 2, 2012 Hey guys, I am planning to do a blowthrough for 2 DC Level 4 12s in a few weeks, and I want to do a 6th order. I need a little help tho. How/what do I tune the ports to, what kind of airspace ratio do I need to do, and where can I get a boot? Thanks ahead of time. 1989 Dodge D150, 318 LA; Holley Fuel InjectionBuild Log:http://www.stevemeadedesigns.com/board/topic/72838-dc-dodge-d150-blowthrough-thread-updated-pics-fixed-2-level-4-15s-wlvl-5-coils/Truck Add-ons: 20" rims2/4 drop15% tintBucket seatsK&N air filterSmog Pump deleteStereoWORK IN PROGRESS2 DC Level 4 15s with Level 5 Coils1 Audiopipe AP15001D (Soon to be a Crescendo BC3500)JBL 650W amp (unsure of model)4 6x9 Rockford Prime 3 ways2 Soundstream TWS.4 Dome tweetersKnuKonceptz 1/0 Power Wire *3 Kinetik 2400s and a Mechman 270A alt in the future* Link to comment Share on other sites More sharing options...
john253a Posted May 3, 2012 Report Share Posted May 3, 2012 i use accordion rubber, as for 6 order 2-3x recommend net volume is somewhere around what you will need for each sub Link to comment Share on other sites More sharing options...
Ram1989custom Posted May 4, 2012 Author Report Share Posted May 4, 2012 I figured I would need to go with the accordion rubber boot, and do you know much about tuning the 6th order? Not too worried about the second port, just the first one, lol. I've been looking around and seen people tune the first one crazy low and the second one in the 60s. 1989 Dodge D150, 318 LA; Holley Fuel InjectionBuild Log:http://www.stevemeadedesigns.com/board/topic/72838-dc-dodge-d150-blowthrough-thread-updated-pics-fixed-2-level-4-15s-wlvl-5-coils/Truck Add-ons: 20" rims2/4 drop15% tintBucket seatsK&N air filterSmog Pump deleteStereoWORK IN PROGRESS2 DC Level 4 15s with Level 5 Coils1 Audiopipe AP15001D (Soon to be a Crescendo BC3500)JBL 650W amp (unsure of model)4 6x9 Rockford Prime 3 ways2 Soundstream TWS.4 Dome tweetersKnuKonceptz 1/0 Power Wire *3 Kinetik 2400s and a Mechman 270A alt in the future* Link to comment Share on other sites More sharing options...
