I went to marks house (mach 5 audio ) 3 days ago and picked up 4 mj 18's

So i had to take out the old BTL

left my van empty and lacking bass...untill...20 cubes and 30 hz later

yes, thats my wire running above the carpet....no i wasnt too lazy to run it under the carpet i just have this place mat carpet the previous owner used in the back of the van so i just put it over the wires, you cant see them and the carpet doesnt move unless i move it.

its not a ton louder then my single 15 BTL, but these are tuned to 30hz and i think they might move a bit more air

yea the box is fugly but what box isnt after havin 4 big black monsters pounding away in it.

Four 18's aren't louder than a single 15? You're serious?

And yes, that is the fugliest box I've ever seen.

I hope there are more ports on the other side because whats currently there is far from sufficient.

thats what i was gathering from reading and psp-inc.com to use for ports for the boxes:( they are 6inch ports not 4

that's NOT right? I know a BTL can take 4000Wrms+ but same amp same ohms/power 4 18's should/WILL be a lot louder like 6/10db's louder?

Nice. Mine got a lot louder once they broke in. Sell me your BTL.

the volume is fine for me, i didnt want a fart cannon, now i gotta take out my cd player and hook up the constant power...somthing got messed up during the instal and my headunit resets everytime i turn off the car

yea im comming out sat forsure wanna see what everyone has, wouldnt mind takin a look at some other guys with mach 5 stuff im sure theirs a few more in the city, anyone wanna buy a btl

for $180 my brow will

How much let me know. I did a 143.4 with my 4 MJs in an Astro with 1k total power.

yea how much are you asking for the BTL

yea how much are you asking for the BTL

no idea to be honest but it would buy me a battery so im tempted now

so 8 6' ports at 9 and a half hummm could do that but where can i get that much cardboard from i tossed all my boxes out now!!! jk..gotta love sono tubes

i had my input really low for my ipod on the headunit and forgot all about it so thats why they seemed not nearly as loud...but i really wanna do the ports now

you should paint the box black after u redo ur ports

yea the box isnt finished wasnt sure about ports so i didnt wanna finish it off yet

instead of running the non-flared ports, you should go with a large slot port along the bottom of both boxes. I found it easier and you will get the amount of port area that you will need for 2 18s per box. If you are going to go with the 6" ports, try finding some flared ends.

haha what "box" wouldnt look ugly with 4 big black things pounding in it....hmmm....

ugly and dont forget loud

I don't see a problem with the vents at all. He's not throwing a ton of power at them, no big competitions so, yeah. He should be well with the acceptable range for vent mach, hell even slightly below.

BTW, you're nuts.

ok its tuesday going on wednesday

scores please

80

well im rebuilding the box so i can fit all 3 ports on one side but its still gunna be just as ugly as anything would be with 4 18 inch black drivers pounding away inside it...no pun intended i swear.

yea the power part is the only thing i kinda would like to change i should of maybe went with the 4ohm instead of 8 since my amp runs at 2ohm and its not too stable from what i hear at 1...but i bet with box rise id be okay oh well...just need more 18;s to even it out:D
