KICKERKX1200 Posted March 19, 2008 Report Share Posted March 19, 2008 i am doin a blow through in a 03 ranger ex-cab for a friend. it will be 2 2008 12" l5's. wanting it tuned around 34hz. can any one suggest total cubic feet and sq inches of port that would give a wow factor for being two 12's. or should i just use the specs that kicker has which is i think 3.25cf plus port. also he will be using a zx1000. thanks for any help.

The biggest thing is how much space you are working with and how much power you give them. 1993 Mazda Mx-3 Subs: 2 18" DC Audio Lvl 4 D.7 Highs amp: Sundown SAX-100.4 Sub amp: Sundown SAZ-3000D Electrical:Kinetik 1200 under hood, 2-Kinetik 2400 rear All 1/0 KnuKonceptz Wire Power/Ground, Big 3, 8Ga Speaker Wire, KnuKonceptz Karma RCA's Dampening: 120sqft 80Mil Thick Sound Destroyer Mat Goal: 150 DB 149.9 Street Bass Link to comment Share on other sites More sharing options...

Team Sundown's Charles Posted March 20, 2008 Report Share Posted March 20, 2008 no issues with space its a blow through and he is using a zx1000 Hes going to need more power then that. Each speaker is only going to get 250 wrms. He should have atless 2 ZX1000 or 1 ZX2500. They should have 500wrms each. 1993 Mazda Mx-3 Subs: 2 18" DC Audio Lvl 4 D.7 Highs amp: Sundown SAX-100.4 Sub amp: Sundown SAZ-3000D Electrical:Kinetik 1200 under hood, 2-Kinetik 2400 rear All 1/0 KnuKonceptz Wire Power/Ground, Big 3, 8Ga Speaker Wire, KnuKonceptz Karma RCA's Dampening: 120sqft 80Mil Thick Sound Destroyer Mat Goal: 150 DB 149.9 Street Bass Link to comment Share on other sites More sharing options...
