Thats A pretty sick ass song

How do you prove yourself worthy? lol

Ooooohhh perdy...

Alright thanks man, Hopefully I can start on this monday

Thanks man really appreciated, so there is no L shape to the port?

Thats fine, now I just need a cut sheet lol, thats one reason why I used the RE calc. it told me exactly what pieces needed to be cut, and how big lol

No I didnt try that

I was going for 35Hz but couldn't get it lol

I put those in the calc. and it still comes up with a tuning of 29Hz or should I even use the calc., and how would I make it bigger by 1cuft, i cant make the box any bigger than it is on the outside.

How do I find the Displacement

Okay so I used the RE box calculator thing, and i'm gonna try and build my own box and I came up with this. I'm going to be running 4 MTX Jackhammer 12's which require 2 ft of airspace a piece This is what I got from the calc. Box Width: 38.5in Box Height: 17in Box Top Depth: 28in Box Bottom Depth: 28in Wood Thickness: 0.75in Square Port Height: 15.5in Square Port Width: 8in Square Port Length 1: 19.25in Square Port Length 2: 10in Total Port Length: 42in Square Port Diameter: 12.5650986286284in Square Port Area: 124 Square Port Volume Internal: 5208 Square Port Volume Displaced: 5229.375 Box Volume: 5.769ft^3 Box Volume: 9968.375in^3 Tuned Freqeuncy(Fb): 33.629 This is my first time ever using a box calc. so I dont think I got it quite right, but that size port was the only way I could get it tuned to 33Hz, any smaller port to increase box volume and the tuning went down to like 19Hz. So any help would be appreciated, I really wanna do this right and not screw it up.

idk man, when I hooked my radio up everything worked as soon as i turned it on, so its probably not in your headunit, could be bad RCA's, bad amp, bad speaker wires, bad speakers, number of things

Make sure the speaker wires from the amp to the speakers are properly connected, if thats not the problem you may have a bunk amp, or the gains are turned all the way down

Hey I got the same H/U as u do, press and hold the imprint button on the right and it should bring up a menu just check and see if it says Sub.W on or off or whatever it's not that hard, don't be to big of a man to read an instruction manual

Looks like the beginning of a very very bad porno......

you would tap that

Maybe shes the one who got hungry and ate the woman, and everyone just thought she was a very very very very very very very very very very very very EXTREMELY large leapord

Thats awesome! need a recone? lol stop by radioshack and food lion lmao

Don't have the time to try and build one myself, and even if i wanted to I would have to go out and buy all the neccessasary equipemtn i.e. table saw, touter, jasper jig, etc...

Okay, well none of these are actually what im looking for, i need a ported not a sealed

Where can I fidn the probox, i'm jus looking to compare prices

I'm looking for a prefab ported box for 4 12's, anyone know where I could look for one of these? or do they even exist? I'm trying to stay away from building my own, i'm inexperienced and dont have the cash for a table saw, router etc... Any help would be appreciated

Yeah my sony's weere like 2.0 v and my Alpine is 4 volts, so thats probably the problem, I will pull it back out and try regrounding it, thanks for the help man!

i'm not sure, its a pretty loud pop, I mean I grounded the H/U to the ground wire from the harness just like I had the Sony
