no i think it would be better to listen to duran, 29sq inches of port per cube sounds spot on for a DAILY SYSTEM.

because music is dynamic. if your only burping tones then you can count that. if on music do not.

yeah brandon daily whatever you do, do not listen to durans dumbass

Making that recommendation doesn't tell him the exact minimum amount of port area needed to avoid port noise. so you are telling me that he will have port noise with 15-17 per and it will be audible???? are you a dumbass, or just a dumbass. my recommendation is not telling him the minimum amount or port area needed without port noise, its giving him a proper starting point for a daily system with lots of output. While it will reduce port noise your recommendation will make mechanical failure more likely. My estimation gives the OP the minimum amount of port area needed to reduce the likelihood of port noise as well as reduce the chances of mechanical failure. You recommending 15-17 proves your stupidity and your lack of understanding of enclosure design. Stop making recommendations as all of them have been proven incorrect. get real dumbass, no one is going to use 29sq inches per for a daily system. what a retard. stop making like you know. and when were my recommendations proven wrong? or are you talking outta your ass.

even box specs raise tuning as well. long ports kill your low desired impedance. say you have a final ohm load of 1. itll never actually be 1. running at half ohms will be closer to 1 ohm then running at 1 ohm. common sense we all should know.

is that an 8volt out deck??

no dont listen to him. if your going for daily with a little more output, you could go 35-38hz with 15-17 per and you should be fine. that should give you a good star off point. then you can redo the box to your liking. also you should figure out what freq your car likes, or simply do 2 boxes. 1 daily, 1 comp.

ive been running kinetiks for years off my iraggi 260 amp alt. i think if your going hi voltage, ext reg then its not good.

port on the bottom. always.

frequency is important. higher is harder.

this is ALTONS post "FYI the box is EXACTLY in the middle of the specs Fi gives for the 12" Q's. Fi recommends 1.8 to 2.4cuft as optimal for a 12" Q, 3.6 to 4.8 for two obviously. If you notice the notes I specifically mention 4.2cuft NET which means before displacements, there's nothing wrong with the space I've given for the Q's." and i STEALTH said "actually net means after displacements. gross is before. lol" ALTON said "taken directly from the dictionary buddy: gross    /groʊs/ Show Spelled [grohs] Show IPA adjective,-er, -est, noun,pluralgross for 11, gross·es for 12, 13; verb –adjective1.without deductions; total, as the amount of sales, salary, profit, etc., before taking deductions for expenses, taxes, or the like (opposed to net): gross earnings; gross sales. net 1   /nɛt/ Show Spelled [net] Show IPA noun, verb,net·ted, net·ting. –noun 10.Mathematics. the abstraction, in topology, of a sequence; a map from a directed set to a given space. to help with that word: ab·strac·tion    /æbˈstrækʃən/ Show Spelled[ab-strak-shuhn] Show IPA –noun1.an abstract or general idea or term. 2.the act of considering something as a general quality or characteristic, apart from concrete realities, specific objects, or actual instances. 3.an impractical idea; something visionary and unrealistic. 4.the act of taking away or separating; withdrawal: The sensation of cold is due to the abstraction of heat from our bodies" PS IM JUST TRYING TO FIND OUT WHAT IS CORRECT WITHOUT DEBATING WITH 1 PERSON.

wow at this thread. all everyone is trying to do is dog on him. thats what im talking about... and notorious get out, your 7th post is that. fukka you was only here for 2 days and a week and you already talkin shiit.

you could port the middle......... or you could just do standard port back sub back and put the middle armrest down so pressure can tranfer into the cabin more freely. i dont know how just the port into cabin and sub in trunk would work???

ok thanks.

dude port length depends on port area. DC says 17 per and you got 10 per with the 4s. up to you

with 17 per, there will be no audible port noise. if you go with psps, no turbulence as well.

oh so i believe the formula is L x pi x r squared/1728

fyi you should do 3 6inch ports, thatll put you up to almost 17 per. but Round ports are more efficient than square ports. did you tell the DC rep you will be using round ports??? reason being is More air is traveling in open air than against the walls because of the ratio between sqin of port and perimeter of the port.

pi x r squared x 4= port area for 4 4'' ports. so just divide that number by 5.

i ordered real early as well.

yeehee. got my tracking number. but jacob, it only says it weighs 20 pounds? i ordered 2 and i was wondering if it just says that or you only shipping 1 at a time.

since i live in hawaii can you ship mine. itll take longer to get here. haha jk

guarantee.

yeahbuddy, lightweight. yeaah lightweight. lol getting my muscle pharm ASSAULT in tomorrow. i take a multivitamin. optimum performance whey protein. and soon to be assault
