Seyzar18 Posted April 1, 2016 Report Posted April 1, 2016 Ok so I use the 12v websites calculator and I have a question... I put the numbers in for the port size, when I get the total say 6.54... Ok so now if I do 2 ports one on each side of the box "4 subs" would I split that number between both or would I leave it and do that on both sides? Also.. Do you HAVE TO split the box if you do 2 ports?? If you don't what Happens, anything? Last question, if I do split that, can some one tell me what I would cut each site at lol I'm not good with numbers like that. 6 27/50th???

ShadeTreeMechanic Posted April 1, 2016 Report Posted April 1, 2016 Port size is based on box volume only. If you split the box then your ports have to be longer. The benefit of having a single chamber is that the port length will be more reasonable. How many and what kind of subs are you putting in 2.78 cuft? 91 C350 Centurion conversion ( Four Door One Ton Bronco) 250A Alternator (Second Alternator Coming Soon) G65 AGM Up Front / Two G31 AGM in Back Pioneer 80PRS CT Sounds AT125.2 / CT Sounds 6.5 Strato Pro component Front Stage CT Sounds AT125.2 / Lanzar Pro 8" coax w/compression horn tweeter Rear Fill FSD 5000D 1/2 ohm (SoundQubed 7k Coming Soon) Two HDS315 Four Qubes Each 34hz (Two HDC3.118 and New Box Coming Soon)
Seyzar18 Posted April 1, 2016 Author Report Posted April 1, 2016 Their 4 skar ma-8s, if I don't split the box and use 2 ports, the ports are both less then a inch n half.. On each side, tunes to 39 hz the total length is 2.31 inches
Triticum Agricolam Posted April 1, 2016 Report Posted April 1, 2016 If your port is only 2.31" long you don't have anywhere near enough port area. So you want to tune to 39 Hz right? How much power are you goin to be running? "Nothing prevents people from knowing the truth more than the belief they already know it.""Making bass is easy, making music is the hard part."Builds:
Triticum Agricolam Posted April 1, 2016 Report Posted April 1, 2016 Do you have any plans to ever run more power than that? "Nothing prevents people from knowing the truth more than the belief they already know it.""Making bass is easy, making music is the hard part."Builds:
ShadeTreeMechanic Posted April 1, 2016 Report Posted April 1, 2016 With a port that small you might as well make it a sealed box. For maximum output you will need a slot port or some type of flared aero port. With a small box like that, the correct port will have a hard time fitting because it will be so long. It will be a compromise for sure. 91 C350 Centurion conversion ( Four Door One Ton Bronco) 250A Alternator (Second Alternator Coming Soon) G65 AGM Up Front / Two G31 AGM in Back Pioneer 80PRS CT Sounds AT125.2 / CT Sounds 6.5 Strato Pro component Front Stage CT Sounds AT125.2 / Lanzar Pro 8" coax w/compression horn tweeter Rear Fill FSD 5000D 1/2 ohm (SoundQubed 7k Coming Soon) Two HDS315 Four Qubes Each 34hz (Two HDC3.118 and New Box Coming Soon)
Seyzar18 Posted April 1, 2016 Author Report Posted April 1, 2016 Yeah I do, I was told that this amp would be plenty for 4 of them.. Then I get it and realize it's not.. I'll get a bigger amp and make sure it'll handle half ohm
